Research Description
Dr. Alkana uses a multidisciplinary approach to investigate the mechanisms of action of psychoactive drugs at the cellular and molecular levels. His overall goal is to increase understanding of the neurochemical basis of brain function and behavior in order to develop new prevention and treatment strategies for alcoholism, drug abuse and psychological disorders. Current techniques in the laboratory include: Behavioral Loss of righting reflex, locomotor activity, convulsant-anticonvulsant effects, learning and memory, aggression and anxiety. Biochemical chloride ion uptake, high affinity binding, gas chromatographic drug analyses. Electrophysiological 2-electrode voltage clamp. Molecular -- Xenopus oocyte expression system. Hyperbaric (increased atmospheric pressure) novel ethanol antagonist and selective uncoupler of allosteric modulation of ligand-gated ion channels (LGICs). These studies are carried out in collaboration with Dr. Daryl Davies in the Alcohol and Brain Research Laboratory at USC.
