What occurs when benzodiazepines bind to their receptors in the brain?
What occurs when benzodiazepines bind to their receptors in the brain?
Of the GABA receptor subunits, GABAa appears to contain the benzodiazepine receptor, which is distinct from the GABA binding site. When benzodiazepines bind, gating for chloride channels is triggered, resulting in hyperpolarization of the cell and a decrease in neuronal excitation.
