Reflex potentials in postganglionic sympathetic nerves evoked by tetanic stimulation of the tibial nerve. The reflex responses in sympathetic nerves averaged for 60 trials were summarized in the intact CNS (a) and spinalized (b) conditions (n = 4 from four rats). The lower horizontal bars indicate the tetanic stimulation (0.2 ms, 2T, 10 pulses at 100 Hz). The arrows indicate excitatory potentials. Vertical bars indicate percent changes relative to the prestimulus values
