Abstract

Several studies were made on the level of light microscope to examine the various afferents which termi' nate in the amYgdala' Studies with electron microscopic degeneration methods, however, were very limited in number.
Hall (19?2) in her review article on the structural organization of the amygdala described preliminary results dealing with degenerated terminal boutons in the amygdala after lesions involving the pre-optic area and the temporal cortex.
Recently, Wakefleld and Hall ( 19?4) demonstrated degenerated terminal boutons containing flattened vesicles in the central, medial and basolateral nuclei after lesions in the lateral pre-optic area.
The present work is a combined light and electron microscopie investigation to localize the site and mode of termination of the olfactory flbres from the olfactory bulb, and of the neocortical afferents from the inferior temPoral area to the v+ rious amygdaloicl nuclei.
