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
Early long-term potentiation which reflects their deficit in late phase LTP. Training of simple reflexes in Aplysia has shown a strengthening between sensory and motor neurons responsible for those reflexes; on a cellular level, for short-term memory (and thus, early LTP) potentiation leads to an increase in presynaptic neurotransmitter by means of modifications of proteins through cAMP-dependent PKA and PKC. The long-term process requires new protein synthesis and CAMP-mediated gene expression, and results in the growth of new synaptic connections. These findings have led to the question whether there is a similar process in mammals. Input to the hippocampus comes from the neurons
