[3H]Muscimol binding to crude synaptic membrane fractions of the rat central nervous is saturable with a high affinity dissociation constant of 2.2 nM. The regional distribution of this binding in rat brain and the effects of freezing, sodium and Triton X-100 are similar to those previously reported for [3H]GABA binding to the the synaptic GABA receptor site. Also, the substrate specificity of [3H]muscimol binding is identifical to that observed for the GABA receptor. Thus, [3H]muscimol is… CONTINUE READING
