Memory and trauma the one most commonly affected by psychological trauma is long-term memory. Missing memories, changes to memory, intensified memories – all are cases of manipulations of long-term memory. Long-term memory is associated with many different areas of the brain including the hippocampus, amygdala, thalamus and hypothalamus, peripheral cortex and temporal cortex. The hippocampus and amygdala have been connected with transference of memory from short-term memory to long-term memory. Thalamus and hypothalamus, located in the forebrain, are part of the limbic system; they are responsible for regulating different hormones and emotional and physical reactions to situations, including emotional stress or trauma. The
Exceptional memory modulator for storage processes occurring in other areas of the brain. Long-term memories are not created automatically, they must be consolidated over time. Research indicates that it is this consolidation process in which the AC plays an assisting role (there is no evidence that it aids in retrieval). Specifically, McGaugh suggests that emotional arousal activates the amygdala, which regulates the strength of a memory, lending to enhanced memory for emotionally charged events. The amygdala itself is a collection of nuclei with distinct functions, the basolateral AC the most involved with memory. The BL projects into the hippocampus and entorhinal cortex
