[Correlations of the geometric and electrophysiologic characteristics of brain stem neurons in the kitten].
Spike activity of the medially and laterally localized units was compared in the pontomedullar reticular nuclei on 1-5 and 15-30 day old kittens. The amplitudes of spikes, spontaneous and evoked patterns of firing in the lateral and medial groups were different. The ratio of cells responding to single and high-frequency stimuli was lower in the lateral units and higher in the medial ones. The medial units had a more significant background firing activation in the interstimulus intervals. It is supposed that the medial cells reflect the properties of densely ramified giant neurons and the lateral--those of the sparsely ramified units. The difference between their electrophysiological properties may be connected with the dendrite geometry, especially with maximal branching foci of dendrites.
