has been well established in the laboratory.
The Amygdala is an almond-shaped neural structure in the anterior part of
the temporal lobe of the cerebrum; intimately connected with the
hypothalamus and the hippocampus and the cingulate gyrus; as part of the
limbic system it plays an important role in motivation and emotional
behavior.
The hippocampus is a complex neural structure consisting of grey matter
