Figure 8.

Depolarization evokes motion of adjacent hair bundle. Bundle movements when the photodiode was positioned on the bundle of the cell being depolarized (trace 1, bundle 1). Photodiode was positioned on the bundle of the next cell along in the row (trace 2, bundle 2). On returning the photodiode to bundle 1, (trace 3), the same size of response was elicited. For each movement record, the negative excursion at the end of the trace is the 14 nm calibration. On the right is shown two hair bundles, the location of the patch pipette, and the photodiode pair superimposed on bundle 1. P10 rat, CsCl intracellular, maximum MET current of 1 nA.
