Generation of spike activity by dendrites of secondary neurons of the rat olfactory bulb

Experiments on secondary neurons of the rat olfactory bulb showed the existence of a third region of action potential generation. It evidently consists of dendrites. This is shown by the distance from the soma of the point where action potentials arise initially and by the recording of spontaneous action potentials of comparatively low amplitude, not spreading into the axon. Action potentials are generated by apical dendrites and also, perhaps, by basal dendrites. Besides partial action potentials with stable amplitude, partial action potentials with, for practical purposes, a stepwise changing amplitude also were recorded. It is suggested that the amplitude of the partial action potentials is modified by IPSPs in the spike-generating zones.
