Cards

Term
Biological Psychology
Definition
The study of biological bases of psychological processes and behavior
Term
Neuroscience
Definition
The study of the nervous system
Term
Behavioral Neuroscience
Definition
Another term used for biological psychology, but focuses on behavioral functions of the nervous system
Term
Rat Brain Vs. Human Brain
Definition
Rat Brain has everything the human brain does, just less of it.  The difference in quantitative not qualitative
Term
Dualism
Definition
the idea put forth by Descartes that humans have a nonmaterial soul as well as a material body. More modern version: mind and brain are separate
Term
Monism
Definition
prevailing neuroscientific view that the mind and brain are the same thing (the mind is the result of neural activity, the function of hte material brain
Term
Five major perspectives are used in behavioral neuroscience
Definition

1. Describing behavior

2. studying evolution of behavior

3. observing the development of behavior over the life span

4. studying biological mechanisms of behavior

5. studying applications of biological psychology, an in individual behavioral dysfunction

Term
Ontogeny
Definition
the process of growing up and growing old
Term
Somatic Intervention
Definition
alteration of a structure or function to see how behavior is altered
Term
Independent Variable
Definition
the factor that is being manipulated
Term
Dependent Variable
Definition
is what is measured in response to changes in the independent variable
Term
Examples of somatic intervention
Definition

1.(SI) Administer a hormome -- (BA)strength of mating behavior

2. (SI)Stimulate brain region electrically -- (BA)movement towards goal object

3.(SI) Cut connections between parts of nervous system -- (BA)recognition of stimulus

**** SI= somatic intervention

        BA= behaviors affected

Term
Behavioral Intervention
Definition

intervention in a behavior to see how structure or function is altered

 

Term
Examples of Behavioral Intervention
Definition

1. (SA)Changes in hormone levels -- (BI)put male in presence of female

2.(SA) Changes in electrical activity of brain --  (BI)present a visual stimulus

3. (SA)Anatomical Changes in nerve cells -- (BI)give training

**** SA = somatic affects

        BI = behavioral intervention

Term
Correlation
Definition
measures how much a body measure varies with a behavioral measure- but correlation does not imply causation
Term
Neural Plasticity
Definition

describes the ability of the brain to be changed by environment and by experience

The brain is always changing (mostly at the cellular and molecular level)

Term
Reductionism
Definition

breaks a system down into its smaller parts in order to understand it

(Behavioral Neuroscience uses this frequently)

Term
The Nervous system is composed of...
Definition
neurons and glias
Term
The nervous system consists of...
Definition
central and peripheral divisions
Term
Histology
Definition
study of tissue structure and cellular anatomy
Term
Gross Neuroanatomy
Definition
anatomical features visible to the eye
Term
Chemical Neuroanatomy
Definition
the distribution of key chemicals in the nervous system
Term
Functional Neuroanatomy
Definition
categorizing areas by their function
Term
Neuropharmacology
Definition
the study of the effects of drugs
Term
White Matter
Definition
regions comprised of myelinated axons
Term
Grey Matter
Definition
regions comprised of cell bodies
Term
Tract
Definition

bundle or "projection" of axons

tract is also referred to as a nerve when its in the body

Term
Nucleus
Definition
cluster of cell bodies
Term
Afferant
Definition
incoming projection or connection
Term
Efferant
Definition
outgoing projection
Term
Motoneurons
Definition
(motor neurons) contact muscles or glands
Term
Sensory Neurons
Definition
respond to environmental stimuli, such as light, odor, or touch
Term
Interneurons
Definition
recieve input from and send input to other neurons
Term
Plasticity
Definition

ability of cells to change structure, function

*Glia cells in brain to replicate

Term
Replicate Vs Regenerate
Definition

most cells in brain (neurons) dont replicate

***In the Hippocampus and the Olfactory System neurons can replicate themselves

Neurons dont replicate but they can regenerate "sprout a new axon"

Term
Glial Cells
Definition
provide support for neurons
Term
Astrocytes
Definition

star-shaped cells with many processes-recieve neuronal input and monitor activity
