Describe fear conditioning.
A mouse is placed in a box. A tone is played for a few seconds and then while the tone continues to play the mouse is shocked. Repeat this until the mouse is conditioned. Later the mouse can be moved to a different box, with the same tone, and it will freeze. This is a fear response due to reactions in the amygdala. When a mouse is placed in the same box and it freezes this is due to context memory of the hippocampus.
