PSC 137 UC DAVIS MIDTERM 3

Behavioral system

designed fro reproduction, feeding and avoidance of dangerous situations

lateral hypothalamus

autonomic arousal

Periaqueductal

Analgesia, freezing

Lateral Amygdala

where they learn what sounds to fear

Basal Lateral Nucleus

fear context, fear of places

Amygdala is needed for recent and remote memory

true

amygdala is needed for fear context memory

true

Auditory input

Lateral

Basal Lateral

spatial input

Central Nucelus

processes the basal lateral and lateral's input

Active Trace Theory

memories can be traced through a new experience or retrieving a LTM

for amygdala diagram

Lateral is on top, Central in the middle and BLA at the bottom

what does APV do in the amygdala

inhibit LTP and fear memory

tone conditioing

audiroy conditioning

if you give animyosin to the amygdala what happens

Short term memory is not affected

is LTM in the amygdala affected by animyosin?

yes

the genonic signaling hypothsis

behavior needs synaptic plasticity, which leads to protein synthsis which then leads to gene expression

for tone memory test you need

amygdala

for context memory test you need

amygdala and hippocampus

after context fear learning

CREB phosphorylation increases

creb antisens

inhibits log term memory

anisomycin impair short term memory

false

if you impair memory one hour after learning

memory is impaired

if you impair memory 24 hrs after learning

no effect on memory

what happens when a memory is retrieved

protein degradation

what is BDNF required for

consolidation

what is Zif required for

reconsolidation

later conbsolidation happens in the

neocortex

Reconsolidation is the observation that

retrieving a memory makes it easier to disrupt

which of the following would be a major problem for the systems consolidation hypothesis

hippocampus damage impairs recent and remote episodic memories

consolidation of memory is impaired if you add anisomycin at

before more than 3 hours pass after surgery

if you prevent degradation after memory retrieval

anisomycin no longer impairs memory

which of the following brain areas has been implicated in remote memory retrieval?

prefrontal cortex

Anisomycin administration only produces amnesia for memories

that are in an active state

if you block protein synthesis in the amygdala inmediately before or after memory retrieval, which of the following will be true afterwards

animals can retrieve the memory one hour later but not after 24 hrs

which of the following is not true about CREB

it phosphorylates AMPA receptors

freezing is a pre-encounter defensive behavior

false

_________consolidation refers to brain changes that take place weeks, months and years after learning

systems

_____consolidation refers to brain changes that take within 24 hrs of learning
