We attended the first meeting of the newly formed Society for Social Neuroscience, which took place at the Manchester Grand Hyatt in San Diego on Friday, November 12, one day before the opening of SFN 2010. References included at end of post.
The interdisciplinary field of social neuroscience was founded in the early 90s, largely through the efforts of John Cacioppo following publication of influential papers by Leslie Brothers (1990, 1996), who introduced the term “social brain,” and by Cacioppo and Gary Berntson (1992). The society was established in 2009 “to give scientists from diverse disciplines and perspectives the opportunity to meet, communicate with, and benefit” from each other’s work.
The society’s inaugural meeting, organized by John Cacioppo and Jean Decety, featured presentations by a stellar group of researchers, on topics ranging from the regulation of gene expression associated with social behavior in honeybees to cognitive hierarchy reasoning in game theory. A major theme was understanding the mechanisms by which social information acts on the brain. But many of the speakers also addressed the implications of their work for psychiatric disorders on the one hand, and more generally for culture and society on the other.
They had me at Hello. The subject of the opening talk by Gene Robinson of the University of Illinois was the social regulation of brain gene expression associated with intensity of aggression in honey bees. A number of studies have teased out inherited, developmental, and environmental influences on bee aggression – a complex, polygenic behavioral phenotype – by focusing on two strains: docile European honey bees (EHB) and aggressive Africanized honey bees (AHB).
Using microarray analysis to obtain transcriptional profiles of hundreds of individual brains, Robinson and colleagues have shown that aggression in EHB and AHB is regulated by some of the same genes. Their expression is strongly influenced by social (i.e., colony – bees were cross-fostered) and chemical (i.e., presence of the alarm pheromone isopentyl acetate) environments, as well as by developmental stage (older bees are more aggressive than younger bees).
Robinson suggested that inherited differences in honey bee colony defense appear to have evolved via gene expression, in particular in EHB via a “dampening” of transcriptional machinery associated with response to alarm pheromone. In short, this work beautifully exemplifies how “nurture begets nature.”
Webcasts of the meeting presentations by Robert Blanchard, Larry Young, Bruce McEwen, Mario Mendez, David Amodio, Colin Camerer, and Martha Farah, as well as Gene Robinson, will be available on the s4sn.org website soon.
All in all, the society’s inaugural meeting was a great success. Long after the concluding talk by neuroethicist Martha Farah, audience members lingered in small groups outside the ballroom, talking animatedly in the afterglow of a brilliant sunset.
