Abstract

Rat septohippocampal fibres are known to originate from GABAergic parvalbumin-containing, fast-firing, fast-conducting neurons and from cholinergic slow-firing, slow-conducting neurons. In the present electron microscopic study, based on immunocytochemical demonstration of parvalbumin and choline acetyltransferase in transverse and horizontal septal sections, it was shownthat parvalbumin-immunoreactive fibres are myelinated, but the vast majority of cholinergic fibres are not. As revealed, especially in horizontal sections, the cholinergic axons show considerably finer calibres than parvalbumin-containing ones. These results confirm and extend our previous light microscopic findings. It can be concluded that differences in conduction velocities, presence or absence of myelin sheaths and differences in axonal diameters are correlated in the septohippocampal pathway.
