“…The measured endocrine parameters, estradiol levels, uterine ballooning, and vaginal cell cytology, were not affected by stress; however, repeated stress did alter the pattern of BLA activity that normally occurs across the estrous cycle. Earlier studies 72,73 demonstrated that disruption of BLA activity influences the expression of mating-related behaviors but has only modulatory effects on the timing of the luteinizing hormone (LH) with no significant impact on ovulation. Our data are in alignment with this in that stress-induced alterations in BLA activity were not associated with acyclicity as assessed by our measured parameters.…”

Stress is a precipitating factor in depression and anxiety disorders. Patients with these disorders often show amygdala abnormalities. The basolateral amygdala (BLA) is integral in mood and emotion, and is sensitive to stress. While much is known about effects of stress on BLA neuron activity and morphology in males, less is known in females. We tested whether repeated stress exerts distinct effects on BLA in vivo neuronal activity and morphology of Golgi-stained BLA neurons [lateral (LAT) and basal (BA) nuclei] in adult female rats. Repeated restraint stress increased BLA neuronal firing and caused hypertrophy of BLA neurons in males, while it decreased LAT and BA neuronal firing and caused hypotrophy of neurons in the LAT of females. BLA neuronal activity and function, such as fear conditioning, shifts across the estrous cycle. Repeated stress disrupted this pattern of BLA activity and fear expression over the estrous cycle. The disruptive effects of stress on the pattern of BLA function across estrous may produce behavior that is non-optimal for a specific phase of the estrous cycle. The contrasting effects of stress may contribute to sex differences in the effects of stress on mood and psychiatric disorders.

“…The habenula has been implicated in estrogenic modulation of female sexual behaviors in mammals ( Pfaus et al, 1993 ; Lonstein et al, 2000 ). In female rats, the estrogen and progesterone-primed mating behavior is reduced after lesion of the habenula ( Modianos et al, 1974 , 1975 ; Rodgers and Schneider, 1979 ). In addition, the proceptive and receptive components of female sexual behaviors are facilitated when progesterone is implanted in the habenula ( Tennent et al, 1982 ), while this effect is blocked when a progestin receptor antagonist is implanted into the LHb ( Etgen and Barfield, 1986 ).…”

Social behaviors such as mating, parenting, fighting, and avoiding are essential functions as a communication tool in social animals, and are critical for the survival of individuals and species. Social behaviors are controlled by a complex circuitry that comprises several key social brain regions, which is called the social behavior network (SBN). The SBN further integrates social information with external and internal factors to select appropriate behavioral responses to social circumstances, called social decision-making. The social decision-making network (SDMN) and SBN are structurally, neurochemically and functionally conserved in vertebrates. The social decision-making process is also closely influenced by emotional assessment. The habenula has recently been recognized as a crucial center for emotion-associated adaptation behaviors. Here we review the potential role of the habenula in social function with a special emphasis on fish studies. Further, based on evolutional, molecular, morphological, and behavioral perspectives, we discuss the crucial role of the habenula in the vertebrate SDMN.
