Two examples of S1 responses to single and 2-channel stimulation at 5μA. A: This S1 channel did not respond to stimulation at channel 6 or 3; concurrent stimulation on channels 3 and 6 evoked a vigorous response (rate = 1000 pps). B: This S1 channel responded to stimulation on channel 3, but not 25. When both channels were stimulated, the response was nearly eliminated (rate = 100 pps).
