The structure and connections of the amygdala 
The amygdala is anatomically one of the most clearly defined 
‘regions of the anuran brain. Externally it participates some- 
what in the formation of the ventrolateral Tidge termed by 
Gaupp prominentia fascicularis, though this eminence is formed 
chiefly by the lateral forebrain bundle and the associated corpus 
striatum. The amygdala is somewhat pear-shaped, the stem 
of the pear (which is directed forward). receiving the ventro- 
lateral olfactory tract. Internally it is ovoid in cross-section 
and projects into the lateral ventricle at the level of the interv ven- 
tricular foramen (figs. 5 and ali
