Term
General info about Neurons
Definition
-sensory, motor,interneurons
-Parts of a neuron: axons, dendrites, cell body, axon terminals
-sensory info in/motor signals out/ memory circuits/ decision making/ intelligence/ neurons are "information processing"
Term
What does a sensory Neuron do?
Definition
take in info from external environment and turn it into electrical signals
-specialized dendrite endings respond to light, motion, touch, and chemicals
Term
what do motor neurons do?
Definition
motor neurons have connections with muscle fibers through specialized axon endings
Term
what do interneurons do?
Definition
receive information from one directions and shoot it out in another direction
-input from "upstream" neuron
-output from "downstream" neuron
Term
What does afferent mean?
Definition
axons bringing info in (mnemonic: “ascending”
or “admit”)
Term
What does efferent mean?
Definition
axons bringing info out (mnemonic: “exiting”)
Term
motor cortex
Definition
-associated with planning and execution of voluntary movements
-if damaged, there will be problems in the planning and execution of these movements
Term
Somatosensory cortex
Definition
perception, touch, pain
Term
prefrontal cortex
Definition
appears to be disproportionally larger than other parts of the brain in humans
-working memory, creativity, planning
Term
Lobes of the Brain: Frontal Lobe
Definition
higher order cognitive functions
Term
Lobes of the Brain: parietal lobe
Definition
perception, touch, pain
Term
Lobes of the Brain: Occipital lobe
Definition
vision interpretation of visual stimuli
Term
temporal lobe
Definition
language related; memory
Term
hippocampus
Definition
role in memory; functioning long term memory
-navigation (spatial)
-1 on both sides of the brain
Term
amygdala:
Definition
relation to emotion and memory as emotional stimuli
Term
The Lovejoy Hypothesis
Definition
Proposed by C. Owen Lovejoy @Kent State
-Links the advent of bipedality with a unique reproductive strategy
Term
What are the hypotheses for primate brain evolution?
Definition
1. cognitive mapping hypothesis
2.Extractive Foraging Hypothesis
3. Social Intelligence hypothesis (Machiavellian intelligence)
Term
What is the cognitive mapping hypothesis?
Definition
1 of the hypotheses for primate brain evolution,
seeking widely dispersed resources (fruit) favored increased cognitive ability
Term
What is the Extractive Foraging Hypothesis?
Definition
1 of the the hypotheses for primate brain evolution
-seeking hidden food resources, such as insects or roots, increased cognitive ability
Term
What is the social intelligence hypothesis?
Definition
1 of the hypotheses for primate brain evolution
-machiavellian intelligence
-living in groups promoted increased cognitive ability
Term
What are the different hypotheses for human Brain evolution?
Definition
1. cognitive reserve hypothesis
2. general intelligence hypothesis
3. adapted intelligence hypothesis
Term
What is the cognitive reserve hypothesis?
Definition
one of the hypotheses for human brain evolution
-larger brai buffers itself against injury or disease, increases longevity
Term
What is the general intelligence hypothesis?
Definition
one of the hypotheses for human brain evolution
-larger brains give greater efficiency in many cognitive tasks
Term
What is the adapted intelligence hypothesis?
Definition
one of the hypotheses for human brain evolution
-one or several specific evolutionary factors involved: tool use and/or hunting, ecological strategies, social or machiavellian intelligence
Term
What is the Universal Grammar hypothesis?
Definition
-suggests a human-only genetically-based "language organ' in the brain
-language arose in humans sometime in the last 100,000 years
-all natural languages are expected to share certain features-this is the universal grammar
Term
What are some anatomical features related to language?
Definition
1. humans have a lower larynx that increases the possibility of choking
2. human tongues are short and deep, allows humans to produce a wide variety of sounds
3. neural control of structures involved in speech are greater in humans
