- In thirteen anesthetized cats. the amygdala.
hypothalamus. and midbrain structures were stimulated
electrically through stereotaxically implanted
electrodes and the sites making masticatory responses
Active masticatory sites were found almost everywhere
in the amygdaloid nuclear complex, but with
the predilection of distribution in the medial. cortical.
and basal nuclei.
Among hypothalamic structures investigated. the
ventromedial nucleus and the medial forebrain bundle
made masticatory responses most frequently.
Positive points were also found in the subthalamus.
substantia nigra. and less frequently also in the red An inference is drawn as to a possible path of
'efferent masticatory impulses from the amygdala.
