Stimulation and ablation of the amygdaloid nuclear complex result in a variety of somatic, visceral, endocrine and behavioral effects. Since this brain area is a very heterogeneous structure, with a number of rather distinct subdivisions, and since differences in structure obviously implies functional differences, it is reasonable that attempts have been made to correlate structure and patterns of responses.

Stimulation and Regional Ablation of the Amygdaloid Complex with Reference to Functional Representations

Functional localization within the amygdaloid complex in the cat.

Functions of the amygdala.

Numerous reports are to be found in the literature pertaining to a group of somatomotor and autonomic responses in experimental animals which are described by a host of names, the more common of which are rage, fear, or flight. Woodworth and Sherrington58and Bazett and Penfield5described responses in decerebrate cats having many of the elements usually associated with anassumedstate of anger in normal cats. The former authors called these "pseudoaffective reflexes." Starting with Goltz15in 1892, a number of authors7,11,46described affective states in decorticate dogs and cats which Cannon and Britton7termed "... a sort of sham rage." In 1928, Bard2applied the term "sham rage" to a group of behavioral manifestations, predominantly sympathetic in character, which appeared in cats with the caudal and ventral half of the diencephalon and the central nervous system caudal to it isolated from the more
