Immunohistochemical and neurochemical studies of hippocampal cholinergic neurones after ischaemia.

We investigated alterations in cholinergic neurones in the gerbil hippocampus after ischaemia. The cholinergic function of acetylcholine (ACh) release fluctuated over the test period. Choline acetyltransferase (ChAT) immunoreactivity decreased slightly on day 1 and no ChAT immunoreactivity was observed on or after day 4 after ischaemia. Since ChAT… (More)
