Structures of the limbic system include the thalamus, hypothalamus, amygdala, septum and hippocampus.
The amygdala is involved with strong feelings of rage or aggression.
The hippocampus helps control the transferring of present experiences into permanent memories. People with hippocampal damage can not remember recent events for very long and can not create new long term memories. The only long term memories they have is of what happened before their injury.
