Abstract：
:Considerable research indicates that long-term synaptic plasticity in the amygdala underlies the acquisition of emotional memories, including those learned during Pavlovian fear conditioning. Much less is known about the synaptic mechanisms involved in other forms of associative learning, including extinction, that update fear memories. Extinction learning might reverse conditioning-related changes (e.g., depotentiation) or induce plasticity at inhibitory synapses (e.g., long-term potentiation) to suppress conditioned fear responses. Either mechanism must account for fear recovery phenomena after extinction, as well as savings of extinction after fear recovery. This article is part of a Special Issue entitled SI: Brain and Memory.

Changes to intermediate filament stoichiometry due to altered mRNA steady-state levels of NEFL, PRPH and INA is thought to drive protein aggregation, yet the exact cause of these changes is unknown.
