Term
The amygdala is involved in the modulation of _______
Definition
memory consolidation
Term
Following any event, is the long-term memory for the event formed instantaneously?
Definition
no!
Term
The information associated with an event is assimilated into long-term storage over time, via ______
Definition
long-term potentiation
Term
_____, a type of memory impaired following amygdala damage, is mediated in part by long-term potentiation
Definition
fear conditioning
Term
James McGaugh
Definition
a laboratory PI who showed that the amygdala, especially the basolateral nuclei, is involved in mediating the effects of emotional arousal on the strength of the memory for an event
Term
What types of classical conditioning tasks were used to study the amygdala's role on emotional arousal contributing to memory strength?
Definition
inhibitory avoidance (where a rat learns to associate a mild foot shock with a particular component of an apparatus) & more complex tasks (such as the spatial & cued water maze where a rat learns to escape to a platform to avoid water)
Term
______ who do compassionate meditation have been shown to modulate their amygdala, along with their tempoparietal junction & insula, during their practice
Definition
Buddhist monks
Term
In an fMRI study, more intensive ______ activity was found in expert meditators than in novices
Definition
insula
Term
Amygdala neurons show many types of oscillation during emotional arousal, such as ______
Definition
theta activity
Term
How do synchronized neuronal events in the amygdala promote synaptic plasticity?
Definition
by increasing interactions between neocortical storage sites & temporal lobe structures involved in declarative memory
Term
During ______, sensory information reaches the basolateral complexes of the amygdala, particularly the lateral nuclei, where they form associations with memory of the stimuli
Definition
fear conditioning
Term
The association between stimuli & the aversive events they predict may be mediated by ______
Definition
long-term potentiation
Term
Memories of emotional experiences imprinted in synapses of the lateral nuclei elicit fear behavior through neuronal connections with the central nucleus of the amygdala & the ______
Definition
bed nuclei of the stria terminalis (BNST)
Term
The axon terminals from sensory neurons form synapses on dendritic spines of neurons from the ______
Definition
central nucleus
Term
Damage to the amygdala impairs both acquisition & expression of Pavlovian fear conditioning, a form of ______ of emotional responses
Definition
classical conditioning
