A diverse pattern of the spike threshold changes in feline gastrocnemius-soleus motoneurons during stretch reflex activation.

abstract：:The Ca++ -dependence of the repetitive firing of neostriatal neurons was studied in an in vitro slice preparation of the rat neostriatum. Neuronal firing was evoked by injecting depolarizing currents of 100-200 ms duration. In normal conditions, the mode of firing was tonic and showed very little adaptation. The frequ...
