A pentylenetetrazole-induced generalized seizure in early life enhances the efficacy of muscarinic receptor coupling to G-protein in hippocampus and neocortex of adult rat.

We have previously shown that exposure to the anti-cholinesterase eserine provokes interictal-like discharges in the CA3 area of hippocampal slices from adult rats in which a generalized seizure has been induced by pentylenetetrazole (PTZ) when immature (at 20 days). Such increased responsiveness to acetylcholine (ACh) was not associated with any change in… CONTINUE READING
