Term
Diurnal
Definition
Animals (like humans) that are active during the day and sleep at night.

*whether or not you are diurnal or nocturnal is evolutionary
Term
Nocturnal
Definition
Animals that are active at night and sleep during the day.

*Whether or not an animal is nocturnal is evolutionary
Term
Activity Rhythm
Definition
It is the pattern of being asleep and awake for somebody. Activity is during the awake part
Term
Free-Running
Definition
When you have a circadian Rhythm that is driven internally (independent of external cues like the sun)
Term
Entrainment
Definition
When you adjust your circadian rhythm based on outside cues (like for humans it is the sunlight!)
Term
Neural/ Hormonal Circadian System
Definition
First Specialize ganglion cells in the retina take in light information, and then send melanopsin down the retinohypothalamic tract, all the way to the Supra Chiasmatic Nucleus (SCN) in the hypothalamus. Then causes the pineal gland to secrete melatonin depending on the light response, and melatonin is what makes us sleepy! This is our "internal clock" or our circadian rhythm

GRSP

Girsp!
Term
Specialized Ganglion Cells...
Definition
These are what start the Circadian System! These special cells that are in the retina take light info and send it down the retinohypothalamic tract with melanopsin, which is sent to the SCN part of the hypothalamus, which causes the pineal gland to release melatonin into the blood and dictate our sleepiness!
Term
Melanopsin
Definition
This is the hormone that specialized retinal ganglion cells use! Melanopsin is used to send the light info down the retinohypothalamic tract to the to the SCN part of the hypothalamus, which causes the pineal gland to release melatonin into the blood and dictate our sleepiness!
Term
Retinohypothalamic Tract
Definition
This is part of the Circadian Rhythm "internal Clock" system. This is the tract where light messages via melanopsin are sent to the SCN, which go to the pineal gland and release melatonin!
Term
Supra Chiasmatic Nuleas (SCN)
Definition
This is part of the circadian Rhythm Pathway, it is inside the hypothalamus. It is the part that receives info from the retinohypothalamic tract and sends it to the pineal gland
Term
Pineal Gland
Definition
This is part of the circadian Rhythm pathway. It sends melatonin to the bloodstream after receiving light information from the SCN in the hypothalamus
Term
Melatonin
Definition
This is the hormone that is secreted into the bloodsteam by the pineal gland that makes us sleepy! It is usually secreted in humans when we get "nightime" light information and send it down the circadian pathway
Term
Does severing the optic tract stop functionality of the circadian rhythm?
Definition
NO! or it doesnt have to. The optic tract, or the visual cranial nerve, does not eliminate input to the retinohypothalamic tract to the SCN! So if someone is blind by JUST damage to the optic nerve or higher, it won't effect the bodies internal clock!

*NOTE That half of these patients, even with functioning circadian rhythms, suffer from free-running disorder (most likely due to lack of entrainment from the sun)
Term
Free Running Disorder
Definition
This is a disorder where someone "free runs" in their sleep pattern instead of being entrained by the sun. It is common in those who are blind!
Term
Time Isolation Experiment
Definition
Someone named Michael Siffe spent 2 months in an underground glacier with no sunlight (thats awful). He would report when he slept, ate, etc, but got no information in return. This allowed his body to adjust to its own circadian rhythm. They found that our human body adjusts to a day period that is LONGER than 24 hours!
In the experiment, because of this lengthened cycle, he thought it was 28 days earlier than it actually was!

*NOTE the takeaway is that our natural body clock is slightly longer than 24 hrs
Term
When do melatonin levels peak?
Definition
From the pineal gland, they peak at 4 AM!
Term
What time of day does Cortisol Peak?
Definition
Cortisol, from the adrenal cortex, falls the most at 4AM (when melatonin is highest) and rises the most right before we wake up.
Term
What time of day does testosterone peak in men?
Definition
Testosterone surges between 1-2AM!
Term
What time of day does growth hormone surge?
Definition
Growth hormone surges at night, which reflects growth in children, and cellular restoration in adults when we sleep!
Term
Fetal Circadian rhythm
Definition
The mothers melatonin levels will entrain the baby inside the mother to have the correct time of day in the womb! However, this when they are born, and it must create its own rhythm. This becomes difficult and the baby must mature for this to occur
Term
EEG and sleep
Definition
The electroencephaolograph, EEG, records from multiple skin electrodes. It is used in sleep labs to identify sleep states people are in, and can be used to diagnose sleep disorders
Term
Stage 1 of Sleep
Definition
During stage 1 (1-4 actually) is slow wave sleep SWS. In addition to this, stage 1 has:
-very light sleep, easy to wake up
-the alpha rhythm, which is the process of calming our body down and slowing our movements!
Term
Alpha Rhythm
Definition
This is a stage of sleep we achieve during stage 1 of sleep. Emitting alpha waves is the equivalent of "daydreaming" and as our body reaches this stage of sleep alpha rhythm signals the body is "calming down"
Term
Stage 2 of sleep
Definition
Stage 2 (stages 1-4 actually) is slow wave sleeping. In addition, stage 2 can be identified by:
-our eye movements stopping, and our electrical brain acticity becomes even slower
-we have BURSTS of radid fast waves, these are called "sleep Spindles"
Term
Sleep Spindles
Definition
During STAGE 2 of sleep, sleep spindles are rapid bursts of really fast moving waves, compared to the rest of stage 2 which is generally slow
They are considered "sparks" of deep sleep
Term
Stage 3 of Sleep
Definition
Slow wave sleep. This is when our brain waves begin to very much slow down, at a speed known as Delta Waves. At stage 3, the delta waves are intersped with faster waves. At stage 4, it is exclusively delta waves!
*Stage 3+4 due to delta waves are considered "deep sleep." this is when it is hard to wake people up, and it is when bedwetting, nightmares, and sleepwalking can occur!
Term
Stage 4 of sleep
Definition
This is considered the slowest of the slow wave sleep. At this point, the brainwave activity is essentially almost all delta waves, or very slow moving waves. There is no eye movement nor body movement
*Stage 3+4 due to delta waves are considered "deep sleep." this is when it is hard to wake people up, and it is when bedwetting, nightmares, and sleepwalking can occur!
Term
Deep Sleep
Definition
Stage 3+4 due to delta waves are considered "deep sleep." this is when it is hard to wake people up, and it is when bedwetting, nightmares, and sleepwalking can occur!

Waking up from deep sleep results in tiredness and groginess
*it is also when declarative memory consolidation occurs
Term
Delta Waves
Definition
Very slow sleep pattern waves that start in stage 3 and are the exclusive wave in stage 4. They represent "deep sleep"
Term
When does Declarative Memory Consolidation Occur?
Definition
During Stages 3+4 of sleep! "Deep Sleep"
Term
REM Sleep
Definition
Rapid eye movement sleep. This is the final stage of sleep, and occurs after stage 1 (NOT stage 4). REM is characterized by
-fast paced waves
-rapid eye movement
-People becoming paralyzed (inability to move)
-Dreaming

*it is when Procedural Memory Consolidation occurs
Term
When does Procedural Memory Consolidation Occur?
Definition
This occurs during REM sleep!
Term
Neural Mechanism that drive falling asleep
Definition
The GABA networks (inhibitory neurons!) triggered by the BASAL FOREBRAIN increase GABA. This calms the cortical network, and causes us to fall asleep.

-GABA pathway activated by Basal Forebrain
-GABAerigc "sleep on" neurons (GABA sleep Neurons) are most active during deep sleep, least active when awake and REM
Term
Basal Forebrain on sleep
Definition
The basal Forebrain triggers the GABA pathway which causes us to fall asleep (reduce cortical activity)
Term
Mechanism of Waking Up
Definition
Acetylcholine (ACh) networks are activated in the cortex, which is driving by the "reticular activating system"
This is made up of the pons, raphe nucleus, and locus coeruleus!
Term
Reticular Activating System
Definition
These are the parts of the brain that work on waking someone up! This system drives the ACh network in the cortex, activates cortical networks of brain!
It is made up of:
-Pons
-Raphe Nucleus
-Locus Coeruleus

PRL

"pearl"
Term
Mechanism of REM sleep
Definition
Rem sleep is driven by the Pons in the brain. The pons does both cortical excitement, as though you are awake, by sending messages to the thalamus, but also sends messages to the spinal cord to paralyze you. This is what causes the "like awake" sleep.

DRIVEN BY THE PONS
Term
Somnambulism
Definition
This is the fancy term for sleep walking. It occurs during deep sleep (stages 3 + 4)
Term
Hypnagogic Hallucination
Definition
When someone is partially in REM sleep, and the dreams seem "real." It is like half waking up, and then beginning to dream about whats going on in your bedroom

*this is what drives things like "alien abduction" dreams. People will report them, but they are most likely hypnagogic halluncinations (REM Sleep hallucinations)
Term
Sleep Paralysis
Definition
When someone wakes up during REM sleep, but they are still paralyzed! It is brief and should end when the body awakes
Term
Narcolepsy
Definition
When someone randomly goes from being awake into REM sleep! (Think about the random a sleeping dogs in mr pesc's class)
Term
Is Hypnagogic Hallucination the same as Lucid Dreaming?
Definition
NO it is not. Hypnagogic Hallucinations are dreams that seem real, Lucid Dreams are like dreams that we can control. We know we are dreaming
Term
Sleep Deprivation
Definition
This is the loss of ALOT of sleep. When people do not get enough sleep to a deprived extent, they experience things such as:
-impaired working memory (STM)
-Impaired Consolidation of Memory (cant consolidate without sleep)
-halluncinations
-IMMUNE SYSTEM DYSFUNCTION
-and if its really bad, death
Term
Mild Alcohol effects on Sleep
Definition
Initially it increases SWS (stages 1-4), but then it has a rebound effect and disrupts sleep, making it hard for people to fall into deep sleep. Without deep sleep, it reduces the brains ability to consolidate memories
Term
Extreme Effects of Alcohol on Sleep
Definition
Extreme effects take the mild effects 1 step further. Mild effects end with a trouble to consolidate memories due to an inability to fall into deep sleep. Extreme alcohol puts you in an unconscious state, making consolidation impossible! Without any consolidation power, we "black out" and lose all memory
Term
Sleeping in Marine Mammals (Dolphins and Whales)
Definition
Dolphins and whales brains actually sleep ONE HEMISPHERE AT A TIME! This allows for ongoing breathing by going up to the surface from one side, while the other side of the brain rests. DAMN
Term
Emotional Intensity
Definition
The AMOUNT of emotion that is felt by someone.
EX: Either being a little angry, or VERY angry at someone. That difference is a difference in intensity
Term
Emotional Valence
Definition
This is the level of positive/ negative emotion someone is feeling! A negative valence includes emotions like angry or sad, where a positive or high valence includes emotions like happy and amazement

it is essentially your measure of positive emotion
Term
Emotional Self Reference
Definition
This is the dimension of emotion that involves where the emotion is being felt. It ranges from being about yourself completely, to being about someone else / an external stimulus completely

EX: being mad at yourself has high self reference, being mad at someone else has low self reference
Term
What brain structure ENCODED emotional information
Definition
The limbic system takes in emotional messages and encoded them into brain signals
Term
What part of the brain is associated with Fear?
Definition
The Amygdala!
Term
Brain Structures involved in Emotion
Definition
Anterior Cingulate (sad, anger, love, etc)
Posterior Cingulate (happy)
Amygdala (Fear, humor, sex)
Orbitofrontal (mystical)

APAO

A-POW!
Term
3 neural pathways of "good feelings"
Definition
The mesocorticolimbic DOPAMINE pathway (particularly in drug addiction, the SEROTONIN pathways, and the OPIATE (periaquaductal grey) pathways all have an influence on "good feeling" emotions

-Dopamine, Serotonin, Opiate

DOS

Doh-s!
Term
Fear Conditioning
Definition
This is a type of classical condition that is done in animal studied (and little Albert). What happened was a rat was exposed to a loud noise, then an electrical shock! This shock caused the rat to experience fear, and their amygdala activation increased!

After a few trials of noise then shock, the rat was conditioned to think the noise caused the shock! So when the noise was played without the shock, the rat was still scared and the amygdala activation still rose! The rat was "conditioned" to fear and an increased amygdala activation by the sound
Term
Mirror Neurons
Definition
Mirror Neurons that activate the brain as though we are experiencing an event but only from watching the EVENT! It causes us to feel "empathy" for others, but allowing us to feel whatever they might be feeling just by watching them. Mirror Neurons are subsets of neurons, and are placed on the emotional relevant brain structures! EX We have regular and mirror neurons for fear on the amygdala

This is how you get intense when watching kingdom hearts scenes/ the cowboys etc. Feeling the emotions as though they are your own
Term
Autism and Mirror Neurons
Definition
There was a study done that showed that autistic children were unable to have mirror neuron empathetic emotions when viewing other peoples faces.

This results means the MAY lack or have a deficiency in mirror neurons
Term
Sexual Differences in Neural Activation of Emotion
Definition
There are sex differences in how men and women feel and remember certain emotional events. An example of this is the amygdala brain study, where men and women were shown a picture of a scary decaying animal. Their amygdala activation was then recorded, and it showed that Men had stronger responses in their RIGHT amygdala, where are women had greater responses in their LEFT. This shows that gender does play a role on neural activation, and may explain why women are more likely to remember emotional memories more than men
Term
Oxytocin
Definition
This is known as the "bonding" hormone. It is secreted during events like nursing a baby or sex. During those events there are rises in affection in trust, and when that occurs oxytocin is released. The released oxytocin inhibits negative emotions like fear and anger! Oxytocin when bonding makes it harder to be upset!
Term
Testosterone
Definition
Testosterone is highly correlated with aggression! It is proven through modulation of testosterone rat studies, where removing/ adding testosterone directly decreases/ increases aggressive behavior!
Term
Excitement Neural Pathway
Definition
The excitement neural pathway is dictated by an initial spike in cortisol (stress), followed by a rush of Epinephrine/ Norepinephrine SPIKE, which causes the good feelings of being excited. This can lead to these good feelings being addictive however, if you can overcome the initial stress response from cortisol
Term
How do people become addicted to jumping out of a plane?
Definition
People become addicted because they are able to overcome the initial cortisol stress level of jumping and capitalize on the E/NE spike that gives them elation. Over time and experience, the cortisol hurdle becomes less and less (people get less stressed), but the E/NE spike remains. This causes people to do it more and more, and even become addicted to the E/NE spike
Term
The fine line of epinephrine and Norepinephrine
Definition
The fine line is considered to be how close positive and negative the excitement feeling they produce can be in humans. Something can be "fun exciting" for someone, while be "terrifying" for someone else (think of a roller coaster)
Term
Why are some memories harder to forget than others?
Definition
Fear memories are harder to forget because fear is tied with the amygdala. It is the same concept with smell memories (where that stimulus goes right to the olfactory bulb and amygdala), fearful memories have the emotional tie to the amygdala which is directly influenced to the hippocampus. Stress hormones also effect the amygdala this way.

**Fear, Stress, and Smell memories are more powerful!
Term
Evidence for Emotions being Biological Based
Definition
Many aspects of emotions are biological, such as our facial response to what emotion we are feeling. They are cross cultural and shown by babies!
Term
Evidence for Emotions being Environmental Based
Definition
While many believe emotions are biologically based, factors of these emotions, such as intensity and response, can be environmentally based. This can be seen with abused children, and how they have a greater fear response to angry faces, based on what they have learned
Term
Learning
Definition
The process of acquisition, or the processes of attaining skills and knowledge
Term
Memory
Definition
The Processes of Storage and Retrieval, or the processes of taking new information and inputting it into our brains, and then having the ability to retrieve that new information from our LTM
Term
Forgetting
Definition
The Process of NORMALLY losing your memories, occurs from interference, failure to store, or unable to retrieve (decay)

** It is considered the process of sorting through relevant and irrelevant info
Term
Amnesia
Definition
This is the process of PATHOLOGICALLY losing your memories, either caused by physical damage or an accident. NOT naturally occuring
Term
Retrograde Amnesia
Definition
This is the loss of your older memories (before an accident) but you are able to form new ones!
Term
Anterograde Amnesia
Definition
This is the inability to form new memories (after an accident), but retaining your older ones
Term
Short Term Memory
Definition
When info is in short term memory (working Memory), It has been in memory for minutes up to a couple hours. It can hold up to 10 things. Through the process of consolidation, it becomes long term memories.
Term
Long Term Memory
Definition
When something has been in our memories for Days, Months, Years, etc. they have been consolidated and maintained in our long term memory.
Term
Working Memory
Definition
Information that we hold onto to use for a current task. It can come from short term memory or long term memory to help us "work"
Term
Consolidation
Definition
It is the transer of short term memories into long term memories! It occurs during sleep.
*Declarative during SWS (1-4), and Procedural During REM sleep
Term
Declarative Memory
Definition
This is a type of LTM, it is literally material that we can store and retrieve with a conscious mind. It is coded by symbols and language.

For a better definition, it is broken up into episodic (memory of events) and semantic (facts) memory to make up all of our declarative memory

*Declarative = being able to explain it
Term
Procedural Memory
Definition
This is a type of LTM, and it is skills and associations that are unavailable to the conscious mind. EX knowing how to walk, ride a bike, write, are all things that we unconsciously know, we don't think declaratively about how to do them.

*Think procedural as being able to show you can do something
Term
Episodic Memory
Definition
This is a type of declarative memory. It is memories of specific events, being able to recall something.
EX: our first day of school
Term
Semantic Memory
Definition
This is a type of declarative Memory, it is memories of FACTS.
EX knowing that tony romo wears number 9 is semantic memory
Term
Process of forming memories
Definition
1. Formation and Encoding
2. Short Term Retrieval
3. Consolidation into LTM
Term
Where are Declarative Short Term memories Processed (ST held and Consolidated) in the brain?
Definition
They are Processed in the Medial temporal Lobe!
This structures are:
-MTL
-Hippocampus
-Entorhinal Cortex
-Perihinal Cortex

MEPH

Mef!

This process is everything from encoding, retrieval, and consolidation!
Term
Consolidation of Declarative Memories
Definition
Once D-memories are processed in the medial temporal lobe (MEPH: MTL, hippocampus, entorhinal cortex, perihinal cortex), they are consolidated by being transferred from the to the hippocampus to CORTICAL NETWORKS. Once they are in our cortical networks, they are no longer hippocampus dependent, and thus are true long term memories
Term
Hippocampus Dependent Memories
Definition
These are declarative memories that have no been fully consolidated yet, but are in the process of being processed by the medial temporal lobe (MEPH). Once they are fully consolidated, they are sent to the cortical networks, and once there they can be retrieved directly from there, and are no longer hippocampus dependent
Term
Where are Consolidated Declarative Memories?
Definition
The Cortical Networks of the brain
Term
Medial Temporal Lobe
Definition
This structure of the brain is the part that processes SHORT TERM declarative memories. Its structures are

-MTL
-Hippocampus
-Entorhinal Cortex
-Perirhinal Cortex
Term
HM
Definition
HM was a dude that went through a Medial Temporal Lobe Lobotomy. This unfortunately gave him anterograde amnesia, BUT ONLY declaritive memories. His procedural memory structures, and thus his skill learning memory, was still in tact. This is shown by his ability to draw stars left handed. He doesn't remember practicing each day, but each day he gets better
Term
Korsakoffs Syndrome
Definition
This is when people drink NOTHING but alcohol and it causes a vitamin deficiency. This can also cause declarative memory loss from the chronic alcoholism, due to the loss of vitamins being degenerative on the cortex (where LTM stores D-memories)
Term
Emotional Memories
Definition
When emotions are attached to encoded information, the info is "helped" coded by the Amygdala. This makes it harder to forget Emotional (fearful, stress, smell especially) memories!
Term
Where are Procedural Memories Processed (ST held and consolidated) in the brain?
Definition
The Basal Ganglia, Motor Cortex, and the Cerebellum

BCM

Bikum!
Term
Amygdala Damage on Memory
Definition
Amygdala damage would cause an impairment on the formation and retrieval of emotional memories!
Term
Delay to Match Sample Task
Definition
This is a way to test someones Short term memory! First they are shown a stimulus (like a light or a pattern) and then they are asked to wait. After the waiting period, they are given choices of other stimulus, and must pick the best one that "matches." The ability to choose correctly reflects ability to hold things in STM for periods of time
Term
Spatial Location Recognition Memory Task
Definition
This is the memory task where a rat in put into a maze, and shown where a piece of food is hidden. Afterward, there is a delay, and it is tested to see if it can find the food again. This tests the rats "SPATIAL MEMORY," or its cognitive map, by its ability to remember conceptually where it has been
Term
Response Recognition Memory Task
Definition
This task is seen to see whether or not people/ rats are able to recognize previously encountered events/ objects/ people.

In class, rats were shown a pattern, and a door opens to get food. Then there was a delay, a varying delay, and rats were then asked to repeat the pattern, getting food if they got it correct. The longer the delay, the less rats got it right
Term
Object Recognition Memory
Definition
It is the ability to discriminate an object/ stimulus you have seen and ones you have not. It tests humans/ rats EPISODIC memory!
Term
Spatial Memory
Definition
This is the abilities of our "cognitive maps" or our ability to navigate and remember where we are. It, like the retrieval and consolidation of STM, is done by the hippocampus!

*Cabbies in London have LARGER hippocampuses, probably because of the larger spacial memories from driving around the city
Term
Long Term Potentiation
Definition
This is the process of something becoming consolidated and stored in memory. Information is stored after a synapse changes its circuits based on the activation pattern of neurons.

*it is the LONG LASTING enhancement of a neural pathway resulting from neuron communication. Synapses changing to make the connection stronger, make Long term memory last
Term
Hypnotism
Definition
Hypnotism is a way of causing retrograde memory disruption, or forced "forgetting" as long as a subject is receptive to the hypnotism. However, it shows that these people still have these memories subconsciously, but they can be hypnotized away from retrieving them

*blocking of memories can also occur with emotional memories (repression)
Term

Definition
-Emotional Responses to stimuli
-Recognition-Memory Task
-Operant head turn tasks/ sucking tasks
-Bayley Scales

Term
Emotional Response to Stimuli Test
Definition
One way we can test babies is just seeing their response to different stimuli.
EX: playing songs and seeing their reactions
Term
Recognition Memory Task on Babies
Definition
This is a way of testing babies that is essentially testing habituation. When a baby stares at something longer, it means they see it as new! By looking at something only for a little bit, they see it as familiar.
Term
Operant Conditioning Head Task
Definition
This is a way of testing babies. Infants had to turn their head for specific stimuli. However, they would only turn their heads for the toy condition, not the "Not toy" condition. This shows they can discriminate the stimulus!
Term
Bayley Scales
Definition
This is a way of testing babies. It is testing babies on tasks that are considered "norms" for their age
Term
EEG on Babies
Definition
This is a way to test babies! It is showing them a stimuli and testing their brain wave patterns to see if they are learning

Term
When do kids start to use adult like grammar and full sentences?
Definition
4-5 years!
Term
Left Hemisphere Plasticity Epilepsy Study
Definition
Children with Epilepsy experience seizures in the brain. When that part of the brain that causes the seizures is removed, the seizures stop. BUT in addition to that, if the brain part is removed before a critical period, that part of the brain can be replaced by the other parts via plasticity. In the one case in class, the kid has his left side completely removed, and because he was young enough (7 years old), the right side was able to take over, and his language and development were almost normal!
