Caroline published a paper in the journal Brain Structure and Function entitled Age and sex differences in oxytocin and vasopressin V1a receptor binding densities in the rat brain: focus on the social decision-making network. Caroline, Max, Sara, Ari, Remco, and Alexa demonstrated the presence of age (juvenile versus adult) and sex differences in the binding density of the oxytocin receptor (OTR) and vasopressin V1a receptor (V1aR) in the rat brain, particularly, in brain regions that form the social decision-making network. We discuss in the paper that age differences in OTR and V1aR binding densities may have implications for the regulation of social motivation (through higher OTR binding in striatal areas) and social and spatial memory (through age differences in OTR and V1aR in the hippocampus, lateral septum and mammillary nuclei) in juveniles, and for the regulation of adult-typical social behaviors (through higher OTR and V1aR in nodes of the social decision-making network and higher OTR in cortical areas). We further showed, for the first time, that most sex differences in OTR and V1aR binding are already present at juvenile age and are found in regions showing a further increase in binding density in adults. We discuss that these regions represent a unique network in which to expect both age and sex differences in the regulation of social behavior. Further research is needed to determine the behavioral relevance of age and sex differences in OTR and V1aR as well as the mechanisms that underlie these age and sex differences.
Remco and Alexa attended the Biannual Meeting of the FENS Forum of Neuroscience in Copenhagen, Denmark. Remco presented a poster and Alexa chaired a symposium on "Neurobiology of social reward and attachment, with speakers Louk Vanderschuren (University of Utrecht, the Netherlands), Siri Leknes (Oslo University Hospital, Norway), Larry Young (Emory University, USA), and Alexa.
Alexa has been promoted to Associate Professor with tenure as of July 1, 2016!
Citations to Alexa's publications reached 3000 on Google Scholar! There are two additional measures of impact. The first is the h-index, which is a measurement that aims to describe the scientific productivity and impact of a researcher, and is 30 which means that 30 of Alexa's publications have at least 30 citations each. The second is the i-10 index which is 40 and indicates that 40 of Alexa's publications have been cited at least 10 times.
Kelly published a paper in the journal Neuroscience entitled Role of the oxytocin system in amygdala subregions in the regulation of social interest in male and female rats. Kelly and co-authors Andrea Alonso, Remco, and Alexa showed that the central amygdala, a brain region involved in fear and anxiety, also modulates social investigation behavior in adult male rats. Specifically, pharmacological blockade of the oxytocin receptor in the central amygdala decreased the investigation of a juvenile rat in males. Interestingly, the same treatment failed to alter social investigation in females. Furthermore, Kelly is the first to demonstrate that the extracellular release of oxytocin in the central amygdala is similar between males and females under baseline conditions. Surprisingly, oxytocin release did not increase in males during social investigation while it decreased in females showing low levels of social investigation. Combined, these results suggests that baseline release of oxytocin in the central amygdala is sufficient to facilitate social investigation in males, while it may serve a different function in females.
Brett, Caroline, Kelly, and Nick presented their work at the 10th annual meeting of the Organization for the Study of Sex Differences in Philadelphia, PA.
Daniel Cho was honored as Scholar of the College at Boston College. The Scholar of the College award is a designation awarded to exceptional students who have excelled academically in their undergraduate studies and who have done substantial independent scientific work of the highest quality in their senior year. Daniel was supervised by Kelly Dumais (on photo).
Ari Ratnaseelan, Grace Ro, Christine Yuan, Daniel Cho, Liz Nussbaum, and Sara Li presented posters on their research projects at the annual Psychology Undergraduate Research Conference at Boston College.
Nick and Caroline gave talks about their research at the annual Graduate Research Day of the Department of Psychology at BC.
Kelly Dumais is the 2016 recipient of Boston College's Donald and Helene White Dissertation Award for the best dissertation in the field of social sciences. Congrats to Kelly!
Kelly Dumais successfully defended her dissertation!! Her committee members were Profs. Alexa Veenema (BC), Gorica Petrovich (BC), Elizabeth Kensinger (BC), and Craig Ferris (NEU). Kelly is author on five peer-reviewed articles, on one review article, and on one book chapter. Kelly received three fellowships: the F31 NIMH Ruth L. Kirschstein NRSA Fellowship, the Engelhard Pingree Research Fellow, and the Dissertation Research Fellowship (both awarded by BC GSAS). We celebrated Kelly's successful PhD completion with champagne. Congrats to Dr. Kelly Dumais!
