NEUROSCIENCE: UNIT 1 QUESTIONS
WITH 100% CORRECT ANSWERS {
GRADED A+}
Neuroscience - ✔✔study of the nervous system
behavioral neuroscience - ✔✔the study of the biological bases of psychological
processes and behavior
Why study behavioral neuroscience? - ✔✔fundamental discoveries in biological
psychology research may contribute to a greater understanding of brain disorders
and the development of effective treatments
around the world, 20% of people suffer from neurological or psychiatric illness.
different levels of analysis in behavioral neuroscience: - ✔✔molecular level
synaptic level
,cellular level
circuit level
brain region level
neural systems level
organ level
social level
molecular level - ✔✔membrane receptors on the cell membrane receive
neurotransmitters
synaptic level - ✔✔interface between two neurons
cellular level - ✔✔single neuron
circuit level - ✔✔multiple neurons communicating; local neuron circuit
brain region level - ✔✔visual cortex
neural systems level - ✔✔networks of multiple brain regions; eyes and visual
brain regions
organ level - ✔✔different divisions of the nervous system; brain, spinal cord,
peripheral nerves, and eyes
,social level - ✔✔individuals behaving in social interaction; deals with behavior
somatic intervention - ✔✔manipulating the body/brain may affect behavior; how
does physiological change affect behavior?
behavioral intervention - ✔✔manipulating the behavior may affect the body and
the brain
correlation - ✔✔measure how closely body/brain and behavior co-vary
to test for somatic variable: - ✔✔behavioral intervention is used on behavioral
variables
ex. putting a male in the presence of a female to test for changes in hormone level
to test for behavioral variables - ✔✔somatic intervention is used on somatic
variables
ex. administering a hormone to test the strength of mating behavior
control group - ✔✔identical to the experimental group except that they do not
experience any alteration or treatment
within-subjects experiment - ✔✔the control group is the same set of subjects
tested before alteration or treatment (tested at two different time points)
, the people are used as their own control group
between-subjects experiment - ✔✔the experimental group is compared to a
separate control group that has been treated identically except for the manipulation
there are two different sets of people, one set will receive treatment of interest and
the other set will not
independent variable - ✔✔the structure or function that is being altered; the
behavior
dependent variable - ✔✔the response that is measured, such as a behavior; the
body changes
positive correlation - ✔✔if both measures increase or decrease together
negative correlation - ✔✔if one measure goes up while the other goes down
correlation may show an association, but... - ✔✔cannot prove causality
All animals... - ✔✔use DNA to store genetic material
All vertebrates... - ✔✔have a backbone and spinal cord (central nervous system)
all mammals... - ✔✔have fur/hair and a neocortex; allow for analogous studies of
cortex
