[The characteristics of the formation of temperature information in afferent units].

Impulse activity of single afferent fibres of the spinal cord dorsal roots of cats was investigated under local mechanical, heat and cold influence on receptive fields of their skin. These influences did not change the frequency of impulsation, but changed redistribution of interimpulse intervals. It is supposed that formation of polyfunctional properties of single afferent fibres is realized due to their polychannel information.
