Gregory Ball is now Dean of the College of Behavioral and Social Sciences at the University of Maryland, College Park

Greg Ball has been appointed Dean of the College of Behavioral and Social Sciences (BSOS) at the Univ of Maryland, College Park. BSOS is the largest college at UMCP and includes 10 department and 6 centers. Ball will continue his research program with a laboratory in the Dept of Psychology.

Welcome from the President

SBN President Cheryl Sisk.

Welcome to the website of the Society for Behavioral Neuroendocrinology (SBN). Since 1996, the SBN has been promoting intellectual exchanges between scientists who have interests in the interactions of the nervous system and the endocrine system on behavior and in the influences of behavior and the environment on neuroendocrine systems. We are an inclusive society with a very diverse membership. Our members are interested in quite an array of behaviors – reproductive behavior, parental behaviors, social behaviors, eating and drinking, responses to stressors, learning and memory, aggression and more, as well as mental health. We are interested in a wide range of species, from simple organisms, like c. elegans to humans and everything in between. We are interested in interactions at the molecular, cellular, and organismic/behavioral level of investigation. We work in laboratories, as well as in the field. Many of our members study natural behaviors, which in turn shed light on behavioral disorders, which often have strong neuroendocrine components. This rich mixture of ideas and approaches can be seen in the Society’s journal, Hormones and Behavior , and can be enjoyed at our vibrant, annual meetings.

In rough-skinned newts, Taricha granulosa, exposure to an acute stressor results in the rapid release of corticosterone (CORT), which suppresses the ability of vasotocin (VT) to enhance clasping behavior. CORT also suppresses VT-induced spontaneous activity and sensory responsiveness of clasp-controlling neurons in the rostromedial reticular formation (Rf). The cellular mechanisms underlying this interaction remain unclear. We hypothesized that CORT blocks VT-enhanced clasping by interfering with V1a receptor availability and/or VT-induced endocytosis. We administered a physiologically active fluorescent VT conjugated to Oregon Green (VT–OG) to the fourth ventricle 9min after an intraperitoneal injection of CORT (0, 10, 40μg/0.1mL amphibian Ringers). The brains were collected 30min post-VT–OG, fixed, and imaged with confocal microscopy. CORT diminished the number of endocytosed vesicles, percent area containing VT–OG, sum intensity of VT–OG, and the amount of VT-V1a within each vesicle; indicating that CORT was interfering with V1a receptor availability and VT-V1a receptor-mediated endocytosis. CORT actions were brain location-specific and season-dependent in a manner that is consistent with the natural and context-dependent expression of clasping behavior. Furthermore, the sensitivity of the Rf to CORT was much higher in animals during the breeding season, arguing for ethologically appropriate seasonal variation in CORT's ability to prevent VT-induced endocytosis. Our data are consistent with the time course and interaction effects of CORT and VT on clasping behavior and neurophysiology. CORT interference with VT-induced endocytosis may be a common mechanism employed by hormones across taxa for mediating rapid context- and season-specific behavioral responses.

The masculinizing effects of prenatal androgens on human neurobehavioral development are well established. Also, the early postnatal surge of androgens in male infants, or mini-puberty, has been well documented and is known to influence physiological development, including penile growth. However, neurobehavioral effects of androgen exposure during mini-puberty are largely unknown. The main aim of the current study was to evaluate possible neurobehavioral consequences of mini-puberty by relating penile growth in the early postnatal period to subsequent behavior. Using multiple linear regression, we demonstrated that penile growth between birth and three months postnatal, concurrent with mini-puberty, significantly predicted increased masculine/decreased feminine behavior assessed using the Pre-school Activities Inventory (PSAI) in 81 healthy boys at 3 to 4years of age. When we controlled for other potential influences on masculine/feminine behavior and/or penile growth, including variance in androgen exposure prenatally and body growth postnally, the predictive value of penile growth in the early postnatal period persisted. More specifically, prenatal androgen exposure, reflected in the measurement of anogenital distance (AGD), and early postnatal androgen exposure, reflected in penile growth from birth to 3months, were significant predictors of increased masculine/decreased feminine behavior, with each accounting for unique variance. Our findings suggest that independent associations of PSAI with AGD at birth and with penile growth during mini-puberty reflect prenatal and early postnatal androgen exposures respectively. Thus, we provide a novel and readily available approach for assessing effects of early androgen exposures, as well as novel evidence that early postnatal aes human neurobehavioral development.

A historical perspective on estradiol's enhancement of cognitive function is presented, and research, primarily in animals, but also in humans, is reviewed. Data regarding the mechanisms underlying the enhancements are discussed. Newer studies showing rapid effects of estradiol on consolidation of memory through membrane interactions and activation of inter-cellular signaling pathways are reviewed as well as studies focused on traditional genomic mechanisms. Recent demonstrations of intra-neuronal estradiol synthesis and possible actions as a neurosteroid to promote memory are discussed. This information is applied to the critical issue of the current lack of effective hormonal (or other) treatments for cognitive decline associated with menopause and aging. Finally, the critical period hypothesis for estradiol effects is discussed along with novel strategies for hormone/drug development. Overall, the historical record documents that estradiol positively impacts some aspects of cognitive function, but effective therapeutic interventions using this hormone have yet to be realized.
