THE ANATOMY OF AGGRESSIVE BEHAVIOR PREDATORY ATTACK Afferent Connections Predatory attack can be elicited from a variety of regions throughout the forebrain and brain stem, an area that extends from the anterior hypothalamus through the midbrain PAG to the level of the pontine tegmentum {see Figures 2A and 2Bl. Concerning the hypothalamic sites from which predatory attack can be elicited, Smith and Flynn 1980a identified cells in a

et al., 19731. A more detailed discussion of the anatomic pathways from limbic nuclei that modulate the attack response is presented below in the section "Limbic-MidDrain Modulation of Aggressive Behavior in the Cat." The other major sites from which predatory attack can be elicited include the following brain stem regions: the midbrain PAG, ventral segmental area, and pontine tegmentum.

Note that flight and affective defense sites are generally situated dorsal to those sites from which quiet biting attack is elicited. A recent study by Bandler (1984~, however, has suggested that affective defense reactions characterized by howling and growling can also be elicited from ventral portions of the periaqueductal gray, especially when stimulation is applied at caudal aspects of this structure.
