Biography

Professor Maidment received B.Sc., M.Sc. and Ph.D. degrees from the Universities of Reading, Southampton and Nottingham, U.K. His doctorate work was on in vivo voltammetry and microdialysis studies of the action of antipsychotic drugs on dopamine transmission in the laboratory of Prof. Charles Marsden. He received post-doctoral training at Stanford University in the laboratory of Prof. Jack Barchas where he developed microdialysis-radioimmunoassy procedures for studying neuropeptide transmission in the limbic system, joining the UCLA faculty in 1990.
