[Characteristics of the vital morphology and bioelectrical activity of a single bushy receptor].

Synchronous morpho-electrophysiological experiment in the frog bladder's single bushy receptor revealed that the receptor vitally stained with methylene blue preserves high functional activity and responded adequately to mechanical square stimuli. The intensity of staining, at that, is related to the spike activity level. The dependence is not linear but has rather a character of inverse proportion. Fast- and slow-adapting terminals were revealed as well as some of their morpho-topographical differences. The slow-adapting receptors were shown to prevail (94%).
