The Dynamic Sensitivity of Muscle Spindles in the Kitten

  • U. Proske
  • J. E. Gregory


This is a report on further studies of the dynamic responsiveness of kitten muscle spindles, previously found to be low. We show that the threshold to vibration is higher than in the adult and the responsive frequency range is smaller. The response to large stretches shows an apparent saturation, not seen in the adult, which may have its origin in the mechanical properties of the immature receptor.
