Fig. 11. Inhibitory synaptic input from neuron #3 to the receptor cell of the stretch receptor. (A) Depolarizing currents applied to neuron #3 (middle trace) produce IPSPs in the rapidly adapting stretch receptor cell (RC1 in Fig. 1A) (bottom trace). Impulses of N3 (asterisks) that occurred with the application of depolarizing currents to neuron #3 and were conducted on the connective show one to one correspondence with hyperpolarizing potentials in a receptor cell (RC1) (arrowheads). (B) Demonstration of synaptic input to RC1. The amplitude of hyperpolarizing potential of RC1 mediated by the injection of current to neuron #3 changed depending on the magnitude of current injected into to RC1.
