Peter Redgrave was awarded a PhD in Psychobiology from the University of Hull in 1977, and a year after was appointed to a junior lectureship in the Dept of Psychology at the University of Sheffield.  He has remained at the University of Sheffield throughout his academic career.  His research has been directed to an investigation of one of the brain’s basic processing units, the basal ganglia.  This group of structures is associated with action selection and reinforcement learning.  Failure of these basic functions in humans are thought to be responsible for a range of neurological and psychological conditions including, Parkinson’s disease, Huntington’s disease, schizophrenia, Tourette’s syndrome, obsessive compulsive disorder, attention deficit hyperactivity disorder and many forms of addiction.  Peter gives lectures on neuroscience to students in the Depts of Psychology, BioMedical Science, and Medicine, and at scientific meetings world-wide.
