I don't know specifically about social interaction, but brain reward 
mechanisms have been the subject of an enormous amount of research, 
with a lot of it taking place in the San Diego area.  One important 
mechanism is dopamine in the nucleus accumbens, thought to play a 
role in cocaine addiction.  Bonidng between mother and infant is also 
believed to involved the hormone oxytocin.

Floyd Bloom, head of the Neuropharmacology dept. at Scripps, and now 
Editor-in-Chief of Science, has published in this area.
