Amygdaloid complex; Extended amygdala; Tetrapods
Definition
In mammals, the amygdaloid complex is a group of nuclei topographically situated in the ventrolateral caudal telencephalic region. It has four major divisions, two of which are mostly pallial and receive major inputs from the olfactory system, one of which is likewise pallial, receives sensory inputs and is highly interconnected with other pallial areas and the fourth of which is subpallial and closely interconnected with the autonomic nervous system. The amygdala is present across tetrapods, with a variety of shapes, sizes and component parts depending on the tetrapod studied.
Characteristics
Overview of the Amygdala in Tetrapods
The amygdala was first identified by Burdach in the early nineteenth century as an almond shaped mass of gray matter through the temporal pole of the human cerebral hemispheres. Subsequently, with the progressive achievement of new technical approaches, it was observed that the amygdala of...
