Neuroscience - Exam 1 With Solved
Solutions.
Biopsychology - Answer The scientific study of the biology of behavior.
Comparative Approach - Answer Study of biological processes by comparing different species. For
example: comparing the behavior of species that do not have a cerebral cortex with the behavior of
species that do, can provide valuable clues about the cortical function.
Independent Variable - Answer the variable that is deliberately changed
Dependent variable - Answer the variable that is measured to access the effect of the independent
variable
Quasi Experimental Studies - Answer studies of groups of subjects who have been exposed to the
conditions of interest in the real world. Not true experiments because potential confounding variables
are not controlled.
Case studies - Answer Studies that focus on a single case or subject. Give in-depth data and testable
hypotheses, but have poor generalizability.
Psychophysiology - Answer the division of biopsychology that studies the relation between
physiological activity and psychological processes in human subjects.
Electroencephalogram (EEG) - Answer A measure of the gross electrical activity of the brain, commonly
recorded through scalp electrodes.
Autonomic nervous system (ANS) - Answer The uncontrollable part of the PNS that participates in the
regulation of the body's internal environment. Consists of the sympathetic nervous system and the
parasympathetic nervous system.
, Comparative psychology - Answer Division of biopsychology that compares the behavior of different
species in order to understand the evolution, genetics, and adaptiveness of behavior.
Nucleus - Answer A collection of soma in the central nervous system.
Tract - Answer A collection of axons in the central nervous system.
Ganglion - Answer A collection of soma in the PNS.
Nerve - Answer Collection of axons in the PNS
Neurons - Answer Cells of the nervous systems that are specialized for receiving and transmitting
electrochemical signals.
Soma - Answer aka the cell body; the metabolic center of the neuron
Dendrites - Answer The short branches emanating from the cell body, which receive most of the
synaptic information from other neurons.
Axon - Answer The long, narrow tube that projects from the soma. Transmits signals from the soma.
Myelin - Answer Fatty, white substance that protects the axon & helps to speed neurotransmission. The
more of this the faster the processing.
Dendrite Spines - Answer (aka post-synaptic membrane); tiny nodules of various shapes located on the
surface of dendrites. Neurotransmitters bind to receptors here. Enzymatic degradation, and reuptake
also occur here.
[Synaptic] Vesicles - Answer Spherical membrane packages that store neurotransmitters molecules
ready for take off near the synapses.
