Dendritic patterns in the somatic sensory cortex of the cat.
Abstract
One of the most significant structural features of the neurons of the central nervous
system is the potentially large synaptic surface they attain by the extension of their
dendritic processes. The total surface area of the dendrites of a single neuron may be
several times that of the cell body of cerebral neurons (Sholl, 1955; Schade &
Baxter, 1960), spinal neurons (Aitken & Bridger, 1961) and cerebellar neurons (Fox
& Barnard, 1957). These studies show that dendrites form 70-90 % of the neuronal
surface of central neurons, so that the total number of dendritic synapses may be
several times that of the perikaryonal synapses. Because of this, the geometrical
patterns of dendrites would be expected to determine the spatial organization of the
majority of the synapses of central neurons. It remains a question what may be the
significance of this spatial organization. Geometrical characteristics of dendrites
are here studied in the posterior sigmoid gyrus of the cat to find out if they can be
analysed into definite pattern
