cONv is sensitive to substrate vibration and is the largest unit in extracellular neck-connective recordings. A, The sequence shows the cONv response to substrate taps (vibro) alone (left), taps with simultaneous SP joint stimulation (first staircase), and SP joint stimulation only (second staircase). B, Intracellular cONv recording during different substrate tapping frequencies. The instantaneous spike frequency plot (top) shows that cONv (magenta) closely followed the substrate tapping frequency (black). C, Intracellular cONv recording and whole-nerve neck-connective recording (conn.) during substrate tapping. Vibrator contact was induced on the rising edge of the stimulus monitor (bottom). cONv was the largest unit in whole-nerve recordings.
