General description

Bicuculline is a phthalide isoquinoline alkaloid, which is extracted from Dicentra cucullaria. It acts as an acetylcholinesterase inhibitor. Bicuculline inhibits slow afterhyperpolarization (AHP).

Application

1(S),9(R)-(-)-Bicuculline methiodide has been used as a gamma-aminobutyric acid (GABA) antagonist to block inhibition in the semicoronal slices. It has also been used for the preparation of organotypic hippocampal slice cultures (OHSCs).

Biochem/physiol Actions

(-)-Bicuculline methiodide is a GABAA receptor antagonist, which acts as a competitive inhibitor of GABA ligand binding to the receptor.

The balance between glutamate-mediated excitation and GABA-mediated inhibition is critical to cortical functioning. However, the contribution of network structure consisting of the both neurons to cortical functioning has not been elucidated. We aimed to evaluate the relationship between the network
