[Cytophysiology of spiny stellate cells of striate cortex and their role in excitatory mechanisms of intracortical synaptic circulation].
This review describes the spiny stellate cells (SCC) which constitute a unique category of cortical interneurons and represent a major component of intracolumnar, lateral and collosal excitation of neocortical pyramidal and nonpyramidal neurons. SCC axons establish contacts with apical dendrites of pyramidal neurons forming cartridge-type synapses en passant with them. SCC establish recurrent connections with inhibitory interneurons and other SCC and also form contacts on themselves through autapses. SCC subtypes are identified, their structure, neurochemical specialization and spatial organization in human and animal neocortex are described. On the basis of the results of author's own investigations and literature data, critical analysis of up-to-date concepts of the histophysiology of recurrent excitatoty and inhibitory neurocirculation in the cortical module, is presented.
