Abstract:
Effects from group II muscle afferents on gastrocnemius-soleus (G-S) motoneurones were compared in unanaesthetized anaemically decerebrated high (C1) and low (Th10) spinal cats. The proportion of G-S motoneurones receiving group II excitation was about the same in low and in high spinal cats. No overall decrease in the strength of group II excitation could be demonstrated after low spinalization. It is postulated that the previously observed low incidence of group II EPSPs in G-S motoneurones in low spinal cats was due to anaesthesia.
