Bicuculline methiodide is a potent GABA(A) receptors blocker. Bicuculline methiodide alters membrane properties and firing pattern. Bicuculline methiodide reduces the Apamin-sensitive afterhyperpolarization, while Apamin is a toxin isolated from bee venom to block small conductance Ca2+ -activated K+ channels. Bicuculline methiodide facilitates burst firing via blocking apamin-sensitive Ca2+ -activated K+ current[1].

In Vitro	Bicuculline methiodide (30 μM) 促进 N-甲基-d-天冬氨酸 (NMDA) 刺激，促进多巴胺神经元的爆发性放电[1]。研究表明，反奖励中枢外侧缰核（LHb）的簇状放电是抑郁症发生的充分条件。LHb神经元常分为三类：沉默型（silent）, 强直放电型（tonic-firing），簇状放电型（burst-firing）[2]。
