Limbic system- a group of brain structures that are involved in various emotions such as aggression, fear, pleasure and also in the formation of memory.

* hippocampus: involved in the formation of long-term memory
* amygdala: involved in aggression and fear
* cingulate gyrus (the circular shape of the cingulate gyrus resembles that of a "limb", hence the name)
* fornicate gyrus
* archicortex
* hypothalamus: controls the autonomic nervous system and regulates blood pressure, heart rate, hunger, thirst, sexual arousal and the sleep/wake cycle. Connected to the pituitary gland and thus regulates the endocrine system. (Not all authors regard the hypothalamus as part of limbic system.)
