General description

Muscimol is a psychoactive isoxazole component, which is found in Amanita muscaria and related mushrooms. It lowers cerebral glucose metabolism and increases the level of 5-hydroxytryptamine in brain. Muscimol has hallucinogenic effects. It is associated with distorted perceptions, nausea and vomiting.

Application

Muscimol has been used:
  • to reduce conditioned fear-expression in lateral amygdala (LA)
  • to eliminate cortical cell response in ferrets
  • to inactivate lateral magnocellular nucleus of the nidopallium (LMAN) in zebra finches
