DESCRIPTION:We have combined sub-second dopamine and serotonin measurement
 s in humans with a generative model of a simple reciprocating social excha
 nge to produce neuromodulatory correlates of inter-personal prediction err
 ors during the reciprocating exchange.    We show that under the cognitive
  demands of the two social tasks presented that serotonin appears to act a
 s the near antipode to dopamine providing direct support for the idea that
  these important neuromodulators are involved in opponent processing – a
 t least at the level of the dorsal striatum.  We will also discuss new inn
 ovations in these electrochemical measurements that strongly suggest that 
 better-than-spike temporal resolution is possible using modifications to s
 tandard carbon fiber electrochemistry.  I will end by discussing our ideas
  on how these data provide new insights into theoretical accounts of dopam
 ine and serotonin interactions.\n\nReferences: \nHula\, A.\, Montague\, P.
