Q

** What is the structures comprise the limbic system and what is their function?

A
  • structures that comprise the limbic system consist of cortical gyri, the hippocampus, the fornix and the amygdala The functions of the limbic system are: - Emotions- fear - Spatial and short term memory - The amygdala is active in aggressive behaviour and fear
