The possibility that zinc (Zn2+) induces giant depolarizing potentials (GDPs) by blocking pre- and postsynaptic gamma-aminobutyric acidB (GABAB) receptors in area CA1 of rat hippocampal slices was investigated. Monosynaptic GABAA receptor-mediated…
We studied the effects of carbamylcholine (carbachol; CCh) on monosynaptic inhibitory postsynaptic potentials (IPSPs) evoked in the presence of the excitatory amino acid receptor antagonists 6,7-dinitroquinoxaline-2,3-dione (DNQX) and…
