GABA A receptors in plasma membranes of neurons are integral oligomers which form chloride channels. The binding of GABA molecules at recognition sites for channel opening triggers a transient increase in transmembrane chloride ion flux. The multiplicity and drug specificity of GABA A receptor, kinetics of channel opening, and desensitization of GABA A receptor and its short‐ and long‐term regulation have been investigated by the use of tracer amounts of the radioactive chloride isotope, 36 Cl − ion. Results and new insights from 36 Cl − ion flux measurements have been reviewed. © 1993 Wiley‐Liss, Inc.
