Dr A. E. Du Beau, PhD, MS, BS, is a neuroscientist with special expertise in forensics. Neuroscience investigates all aspects of the brain’s functionality, inclusive of neurochemical and anatomical processes that underlie behavior, perception, cognition, mentation and consciousness. Dr Du Beau’s neuroscientific expertise includes altered states of consciousness and sleep, alcohol blackout, psychoactive drugs, traumatic brain injury, memory processes, intentionality, violence and criminality. For contrast, psychologists and psychiatrists are clinicians who are principally focused on the mental state of any given patient, diagnostics and establishing a therapeutic relationship. Conversely, neuroscience uses an analytical approach to understanding how the brain works. Dr Du Beau’s doctoral research at the prestigious University of Glasgow (Scotland, United Kingdom) investigated the neurochemical properties of neural systems using an array of sophisticated laboratory, surgica...
