PSB 2000 EXAM #2 QUESTIONS
WITH COMPLETE SOLUTIONS!!
1 of 97
Term
Opiates: How do opiates increase dopamine transmission in nucleus
accumbens?
Give this one a try later!
Blocking...prevents any
Excitatory...stimulates vta neurons to
neurotransmitter release in the
decrease dopamine release.
nucleus accumbens.
, Inhibitory...Removes inhibition
from VTA -> NA neurons -> Neutral...has no effect on dopamine
increases dopamine release transmission in the nucleus
in NA accumbens.

Term
Genetics and Epigenetics: So ____ can affect ____ _____, even in our
offspring!!

environment; dna structure experience; gene expression
lifestyle; health outcomes genetics; physical appearance

3 of 97
Term
Alcohol: What does it do to glutamate and GABA transmission?
Give this one a try later!
, Opiates bind the receptors on the GABA neuron and we get a rebound of
activity. When the pathway is not longer inhibited it is disinhibited. GABA is an
inhibitor
Also works on dopamine (reinforcement) and opiate (pleasure) systems,
including in nucleus accumbens.
Bind to opioid receptors (inhibitory)
Really, these receptors are in most major regions of the brain, so the effects of
opioid drugs are widespread.
( Anywhere they act in the brain is going to inhibit the activity.
Works to inhibit pain transport.)
Increases inhibition within nervous system
Anti-anxiety & intoxicating effects due to this action
Glutamate receptor antagonist
GABA receptor agonist.
(Block our excitatory pathways and ramps up our inhibitory processes.)
Don't know?
4 of 97
Term
Dopamine, NE and epinephrine make up the ______ b/c contain a
catechol group and an amine group.
Give this one a try later!
, glycoproteins peptides
steroids catecholamines
Don't know?

Term
Transcription
Give this one a try later!
Experience; gene Expression Rna --> amino acid chain (protein)
DNA -> RNA Rna -> Protein
Don't know?

often to blame?
