SUMMARY:The role of phasic dopamine signalling in the determination of age
 ncy and the discovery of novel actions - Professor Peter Redgrave\, Depart

DESCRIPTION:An influential concept in contemporary computational neuroscie
 nce is the reward prediction error hypothesis of phasic dopaminergic funct
 ion.  It maintains that midbrain dopaminergic neurones signal the occurren
 ce of unpredicted reward\, which is used in appetitive learning to reinfor
 ce existing actions that most often lead to reward. However\, the availabi
 lity of limited afferent sensory processing and the precise timing of dopa
 minergic signals suggest they may instead play a central role in identifyi
 ng which aspects of context and behavioural output are critical in causing
  unpredicted events.
