General description

A constituent and psychoactive ingredient of the mushroom Amanita muscariathat acts as a potent agonist of GABAA receptors (EC50 = 28 µM and 33 µM in neonatal and adult rats, respectively), with preferential efficacy and selectivity to high-affinity receptor subtypes. Shown to be permeate the blood-brain barrier. Impairs associate and memory functions.

Muscimol has been regarded as a universal agonist for all gamma-aminobutyric acid type A receptor (GABA(A)-R) subtypes. However, brain regional distribution of muscimol's high-affinity binding sites greatly differs from those of other binding sites of the GABA(A)-R. To test whether

A matching-to-position (MTP) paradigm was altered to influence the type of associations a rat would use to solve the task. Our main behavioral manipulation was the application of the differential outcomes procedure (DOP). The DOP involves correlating each to-be-remembered event

The effects of gamma-aminobutyric acid (GABA) on the electrophysiological properties of intracardiac neurones were investigated in the intracardiac ganglion plexus in situ and in dissociated neurones from neonatal, juvenile and adult rat hearts. Focal application of GABA evoked a depolarizing
