title: [The structural dynamics of the afferent flow in the action on the receptor field of a low-intensity stimulant].
abstract: The pattern of changes in afferent flow from a uniform isolated receptor field (3-5 mechanoreceptor units) under the effect of unspecific external stimulus of low intensity, was studied. A diverse dynamics of the afferent flow was observed: the firing rate, relative distribution of discharges in time, the amplitude and the form of spikes, are altered. The changes occur simultaneously, as a rule, which renders the idea of afferent flow's structure rather uncertain. The growth in amplitude and the change in the form of discharges seem to be based on a synchronizing of receptor units excitation. The latter can serve as a premise for actualization of the mechanism of sensory information compression by means of involvement of parallel afferent fibres in the excitation.
