[Changes in the sensitivity of the muscle spindles of fast and slow-contracting muscle fibers following chronic deafferentation].
The activity of muscle spindles was investigated in fast (m. EDL) and slow (m. sol) muscles of the cat 2-5 weeks after chronic deefferentation. The spontaneous activity of spindles in both muscles remains unchanged. The background activity and activity in dynamic and static phases of stretching both in primary and in secondary endings was much in chronic denervated muscle than in control. This increase in spindle activity was more pronounced in the slow muscle.
