Neuropsychologist
A neuropsychologist specializes in neuropsychology, a branch of psychology and neurology that aims to understand how the structure and function of the brain relate to behavior. Aspects of behavior that interest neuropsychologists include attention, memory, language, and intellectual functions. In practice neuropsychologists tend to work in academia (involved in basic or clinical research), clinical settings, forensic settings (often assessing people for legal reasons or court cases), or industry (often as consultants in product design or in the management of pharmaceutical clinical-trials for drug research).Reference: http://en.wikipedia.org/wiki/Neuropsychologist
