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.

Recent studies have shown that women are more sensitive than men to subtle cuteness differences in infant faces. It has been suggested that raised levels in estradiol and progesterone may be responsible for this advantage. We compared young women's sensitivity to computer-manipulated baby faces varying in cuteness. Thirty-six women were tested once during ovulation and once during the luteal phase of their menstrual cycle. In a two alternative forced-choice experiment, participants chose the baby which they thought was cuter (Task 1), younger (Task 2), or the baby that they would prefer to babysit (Task 3). Saliva samples to assess levels of estradiol, progesterone and testosterone were collected at each test session. During ovulation, women were more likely to choose the cuter baby than during the luteal phase, in all three tasks. These results suggest that cuteness discrimination may be driven by cyclic hormonal shifts. However none of the measured hormones were related to increased cuteness sensitivity. We speculate that other hormones than the ones measured here might be responsible for the increased sensitivity to subtle cuteness differences during ovulation.

Psychosocial stress, specifically social isolation, is an important risk factor for the development of a variety of psychological and physiological disorders. Changes in immune function have been hypothesized to mediate this relationship. The current study used the prairie vole (Microtus ochrogaster) model of isolation-induced depressive-like behavior to test whether social isolation led to changes in innate immune function. Specifically, we used hemolytic complement (CH50) and bacteria killing assays to assess innate immunity, in paired or singly housed male and female prairie voles. Further, in a second experiment we tested whether females exposed to an additional short-term social stressor, a resident–intruder trial, would show changes in immune function as well as enhanced hypothalamic pituitary axis (HPA) activity as indicated by elevated plasma corticosterone levels. Socially isolated animals, regardless of sex, had significantly reduced CH50s and bacteria killing ability. Socially isolated females exposed to a resident–intruder stressor also showed reduced CH50s and bacteria killing ability as well as significant increases in aggressive behavior, however, they did not show elevated circulating corticosterone levels. Collectively, these data will help inform our understanding of the relationship between social isolation and physiological and psychological health.

Across human societies and many nonhuman animals, males have greater interest in uncommitted sex (more unrestricted sociosexuality) than do females. Testosterone shows positive associations with male-typical sociosexual behavior in nonhuman animals. Yet, it remains unclear whether the human sex difference in sociosexual psychology (attitudes and desires) is mediated by testosterone, whether any relationships between testosterone and sociosexuality differ between men and women, and what the nature of these possible relationships might be. In studies to resolve these questions, we examined relationships between salivary testosterone concentrations and sociosexual psychology and behavior in men and women. We measured testosterone in all men in our sample, but only in those women taking oral contraception (OC-using women) in order to reduce the influence of ovulatory cycle variation in ovarian hormone production. We found that OC-using women did not differ from normally-ovulating women in sociosexual psychology or behavior, but that circulating testosterone mediated the sex difference in human sociosexuality and predicted sociosexual psychology in men but not OC-using women. Moreover, when sociosexual psychology was controlled, men's sociosexual behavior (number of sexual partners) was negatively related to testosterone, suggesting that testosterone drives sociosexual psychology in men and is inhibited when those desires are fulfilled. This more complex relationship between androgens and male sexuality may reconcile some conflicting prior reports.
