The anatomy of the amygdala.
Endorhinal sulcus is the anatomical landmark for the anterior extension of the amygdala identified by red arcuate line (4). The amygdala; the green structure (2). The two blue dots represent the optic tracts (3). The vertical purple lines represent the anterior limbs of the fornix diving through the hypothalamus (1).

The main output (efferent) fibers of the amygdala:
- Ventral amygdalofugal pathway: longer pathway dives through septal region, brain stem, thalamus, hypothalamus, and finally into the sensory cortex.
- Stria terminals (very similar to the fornix in relation to the anterior commissure); it is divided into three parts in relation to the anterior commissure:
- precommissure fibers
- commissure fibers
- post commissure fibers
