Research has identified that a distressing experience has different effects on two parts of the brain: the amygdala and the hippocampus. More specifically, the lobes have been linked to episodic/declarative memory, which means the damage to these areas of the brain would result in disruptions to declarative memory system. Counter conditioning and rewriting the memory of the events that are related to the sensory cue, may help dissociate the memory from the primer. The medial temporal lobes, the precuneus, the posterior cingulate gyrus and the prefrontal cortex are the most typically referenced with regards to involuntary memories.
