Electrical Activity During the Estrous Cycle of the Rat: Cyclic Changes in Limbic Structures

1968

Changes in electrical activity in the hippocampus and amygdala during the estrous cycle were investigated in the rat to examine the relationship between the limbic system and gonadal function. It has been shown that localized seizure threshold in the dorsal hippocampus was significantly decreased during the interval between the morning of proestrus and morning of estrus. The lateral part of the amygdala behaved in approximately the opposite direction, with an increased threshold during the same period. The thresholds for the medial part of the amygdala had decreased on the night of the second day of diestrus to the morning of proestrus, but had increased above the diestrous values by the night of proestrus.These observations were discussed with reference to plasma gonadal steroid levels and possible regulatory role of limbic areas on the release of gonadotropin. Whereas ovariectomy eliminated the cyclic aspects of activity in the limbic system, a dampened cyclicity was restored by a single injection of 10 ng of estradiol dipropionate in rats at 90-120 days of age. The same dose of estrogen was somewhat less effective in older animals, and it did not establish cyclicity in rats ovariectomized at birth. (Endocrinology 83: 207, 1968)

“…Stimulation of the central nucleus of the amygdala of the dog results in fear and escape responses (Fonberg, 1965). The same is true for the cat (Anand & Dua, 1956;Wood, 1958). Lesions in the same area, however, result in a reduced threshold for irritable aggression in both animals.…”

“…It also seems likely that a portion of the amygdaloid area which, when stimulated, induces escape behavior, also has inhibitory functions in relation to those areas of the amygdala associated with irritable and predatory aggression (Fonberg, 1965;Wood, 1958). Stimulation of the central nucleus of the amygdala of the dog results in fear and escape responses (Fonberg, 1965).…”

“…Bard and Mountcastle (1948) and Wood (1958) reported that ablation of the amygdala in cat produced an increase in aggression. Elements of the Kluver and Bucy (1939) also hint at contradictory patterns of behavior: amygdalotomy in monkeys produces general placidity, yet hyperactivity, hypersexualty, and hyperreactivity to environmental stimuli.…”

Competition is ubiquitous among social animals. Vying against a conspecific to achieve a particular outcome often requires one to act aggressively, but this is a costly and inherently risky behavior. So why do we aggressively compete, or at the extreme, fight against others? Early work suggested that competitive aggression might stem from an innate aggressive tendency, emanating from subcortical structures. Later work highlighted key cortical regions that contribute toward an instrumental aggression network, one that is recruited or suppressed as needed to achieve a goal. Recent neuroimaging work hints that competitive aggression is upmost a cost-benefit decision, in that it appears to recruit many components of traditional, non-social decision-making networks. This review provides a historical glimpse into the neuroscience of competitive aggression, and proposes a conceptual advancement for studying competitive behavior by outlining how utility calculations of contested-for resources are skewed, pre- and post-competition. A basic multi-factorial model of utility assessment is proposed to account for competitive endowment effects that stem from the presence of peers, peer salience and disposition, and the tactical effort required for victory. In part, competitive aggression is a learned behavior that should only be repeated if positive outcomes are achieved. However, due to skewed utility assessments, deviations of associative learning occur. Hence truly careful cost-benefit analysis is warranted before choosing to vie against another.
