Theoretical considerations of local neuron circuits and their triadic synaptic arrangements (TSA) in subcortical sensory nuclei.
Certain sequential models of the so-called synaptic triadic arrangements (TSA) occurring in sensory nuclei are analyzed. The considerations are addressed mainly to the lateral geniculate body. The model is based on the assumption that the neurons establishing these triads consist of conditionally coupled decision-making subunits. It might be concluded that this and similar arrangements could play a role in the discrimination between stationary and moving retinal inputs and in the detection of temporal correlations in certain input channels.
