[Synapsoarchitechtonics of the parietal and acoustic regions of the cerebral cortex of cats].
The synapse architecture of the simcipital and auditory cortex of the cat (fields 7 and 22 after M. O. Gurevich and oth., 1929) was studied electron microscopically. In the both areas of the cortex there are much more axo-dendritic synapses that axo-somatic ones. In the upper layers the synapses are more often formed on small dendrites and thorns, while in layers IV-VI they often occur on the main trunks of large dendrites. The synapses on small branches and thorns of dendrites contain spherical vesicles, and the synapses on on large dendrites are formed by the terminals of two kinds-with flattened and spherical vesicles. The amount of axo-somatic synapses increases towards the lower layers of the cerebral cortes. The synapses on the soma and apical dendrites of the pyramid neurons always contain flattened vesicles; on the stellate neurons there occur perisynaptic terminals with sperical vesicles as well.
