Abstract:1. The effect of tetanus toxin injected into one gastrocnemius muscle on the steady state concentration of several amino acids was investigated in spinal cord half segments, spinal roots and dorsal root ganglia of rats. Care was taken to ensure a symmetrical afferent input to the spinal cord and to localize the segment with the highest concentration of tetanus toxin. 2. In the spinal cord segments containing the highest concentration of tetanus toxin the steady state concentration of glycine was higher on the … Show more
