PSY 260 QUESTIONS AND ANSWERS
which of the following is not a specific criterion for classifying a substance as a
neurotransmitter? -ANSW ability of the substance to travel long distance between the
sight of origin and target area
which of the following is NOT a catecholamine neurotransmitter? -ANSW serotonin
which of the following is NOT a monoamine neurotransmitter? -ANSW Acetylcholine
which of the following is NOT an amino acid neurotransmitter? -ANSW dopamine
the neurotransmitter _____ is found in the nuclei of the basal forebrain -ANSW
acetylcholine
the dopamine neural pathway from the _____ to the nucleus accumbens appears to be
involved in the experience of reward -ANSW ventral tegmental area
a major site of origin of projections using the neurotransmitter serotonin is the -ANSW
raphe nucleus
a major site of origin of projections using the transmitter norepinephrine is the -ANSW
locus coeruleus
noreandrengeric axons project into the -ANSW -limbic system
-thalamic nuclei
-cerebral cortex
drugs that mimic GABAa receptors might be effective in the treating -ANSW anxiety
disorders
in the mammalian brain, the major inhibitory neurotransmitter is -ANSW GABA
the NMDA receptor is a type of receptor for the neurotransmitter -ANSW glutamate
GABA receptors are -ANSW inhibitory
if drug A is found to bind to a certain type of receptor more strongly than drug B, then
drug A is said to have greater -ANSW affinity
, higher doses of a drug tend to increase the proportion of receptors that are bound and
affected by the drug, thereby increasing the response. This relationship is called the -
ANSW dose-response curve
people who have used a particular dose of a drug several times may develop a similar
response to the same dosage of other drugs in the same class. This is an example of -
ANSW cross-tolerance
repeated exposure to a drug leading to a decrease in physiological response is called -
ANSW tolerance
selective serotonin reuptake inhibitors (SSRIs) work by -ANSW allowing transmitter to
accumulate in the synaptic cleft
curare is a drug that selectively blocks receptors for -ANSW acetylcholine
the antipsychotic drug haloperidol is particularly selective for dopamine _______
receptors -ANSW D2 receptors
most antipsychotic medications act by blocking _____ receptors -ANSW dopaminergic
Benzodiazephines, such as diazepam, or other anxiolytics, appear to modulate the
activity of receptors for the neurotransmitter -ANSW GABA
alchohol alters the functioning of the brainier interaction with -ANSW GABA receptors
the main active ingredient found in marijuana is -ANSW THC
cannabinoids have been found to be widely distributed in the brain, but apparently they
are not present in significant numbers in the -ANSW cerebellum
which drug is not found in nature or derived from natural substances? -ANSW
amphetamine
reduced gray matter, absence of the corpus callosum, abnormal brain organization, and
characteristic deformities of the head and face are seen in -ANSW fetal alchohol
syndrome
the ___ model of drug abuse and addiction focuses on the addict's desire to avoid
withdrawal symptoms -ANSW physical dependence
the moral model of drug abuse suggests that addiction is caused by -ANSW character
weakness in addicts
drugs that stimulate the _____ pathway provide powerful positive rewards that may
eclipse the pleasure derived from other activities -ANSW dopaminergic
