"... the amygdalae perform primary roles in the formation and storage of memories associated with emotional events..."
"The amygdalae also are involved in the modulation of memory consolidation. Following any learning event, the long-term memory for the event is not instantaneously formed. Rather, information regarding the event is slowly assimilated into long-term storage over time (the duration of long-term memory storage can be life-long), a process referred to as memory consolidation, until it reaches a relatively permanent state... "
"... emotional arousal following the learning event influences the strength of the subsequent memory for that event. Greater emotional arousal following a learning event enhances a person's retention of that event"
To summarize.. Amygdala is responsible for casting high amplitude emotional arousal into permanent memory!!
This is why I hate it.. ;)
