[Electrophysiological analysis of the spectrum of the fibers of the lateral olfactory tract in rats in vitro].

Total action potentials (AP) of lateral olfactory tract (LOT) have been studied on 200 um sections of olfactory cortex of rat brain. Over-threshold stimulation of a proximal end of LOT was accompanied by five waves at descending phase of AP. The increase in stimulation frequency from 1 to 3 to 10 Hz led to a decrease in amplitudes of all LOT AP components. The data obtained suggest that the composition of LOT fibers is heterogeneous.
