    Abstract:
    Rhythmic contractility of the circular and longitudinal muscular layers of the cat colon in situ, after administration of blocking agents (atropin, phentolamine, and inderal), changes both in it spectral-frequency component and in the contraction strength of each layer, while the correlation between both layers contractions decreased from 69 to 28.9 percent. The colon rhythmic contractility is concluded to be a functionally organized process in conditions of intact innervation, the nervous system playing an active role in coordination of contractions of the circular and longitudinal muscular layers.
