Q

Long Term Memory

A

Vast capacity but subject to forgetting

Retrieving long term memories causes memories to become unstable and susceptible to disruption or alteration

Q

Reconsolidation

A

return of a memory trace to stable long term storage after recall

17
Q

Neuroplasticity

A

ability of nervous system to change in response to experience or environment

18
Q

Long Term Potentiation

A

Occurs in hippocampal pathways consisting of hippocampus, dentate gyrus, and others
Uses glutamate and depends on NMDA and AMPA receptors

19
Q

LTP Process

A

1) Glutamate is released and activates AMPA receptors
2) NMDA receptors have Mg2+ ion blocking Ca2+ channels at rest
3) Stronger depolarization of AMPA depolarizes membrane releasing MG2+
4) NMDA then responds to glutamate and allow Ca2+ to enter
5) Influx of Ca2+ activate intracellular enzymes causing changes in AMPA receptors
