FIGURE 1. Dye- and electrical coupling between taste bud cells in the amphibian, Necturus maculosus.

FIGURE 1.

a, three taste cells were dye-filled after injecting cell 1 with Lucifer yellow (cells 1, 2 are slightly superimposed). Modified from [4]. b, Whole-cell currents recorded from an electrically-coupled taste receptor cell in Necturus maculosus. Current from an action potential in the patched cell (initial inward transient current) was transmitted to and excited a neighboring taste cell, seen as the second, smaller and slower transient inward current (arrow). The patched cell was excited by momentarily stepping the membrane potential from a holding potential of −80 mV to −20 mV. Modified from [9].
