PBSI 340 EXAM 3 QUESTIONS AND ANSWERS
LATEST 2025-2026 UPDATE
hippocampal lesions... - Answer-prevent episodic memory
glutamate release from the presynaptic neuron, a strong depolarization
induces... - Answer-
Genetic manipulations: knockout - Answer-Targeted gene/protein is not
produced
Genetic manipulations: transgenic - Answer-recombinant DNA/RNA
Study conditional knockout diagram - Answer-
cFOS - Answer-- An early response gene in the cell cycle that will go
and activate transcription of delayed response genes such as many
CDK's and Cyclins, tTA
, Doxycycline in transgenic genetic manipulation - Answer-inhibits
function of certain genetic mutations; usually via food; normal when you
feed it to them
NR2 subunit forms - Answer-NR2B - replaced by
NR2A during development, allows more LTP to occur during early life
Optogenetics - Answer-Transgenic technique that combines genetics
and light to control targeted cells in living tissue (ex: Rhodopsin)
escape behavior methods - Answer-shuttle box, wheel turn box
controllable shock group - Answer-master
uncontrollable shock group - Answer-yoked; exhibit learned
helplessness, learning is undermined
Two consequences of uncontrollable learned helplessness - Answer-
motivational deficit
associative deficit
explicit learning - Answer-a learning process that includes the ability to
verbalize about the actions or events being learned; a conscious process;
mediated/declarative
