Simultaneous recordings from a pair of SGI neurons. A, Photomicrograph of the pair of recorded SGI neurons (injected with biocytin intracellularly). B, Recordings of current responses from one cell in voltage-clamp mode (VC) after induction of a single (1) or several (2) action potential(s) in the other cell by current injection in current-clamp mode (CC). C, Spontaneous membrane potentials in control solution (1), in the presence of 10 μm Bic and low (0.1 mm) Mg 2+ (2), and after washing out Bic and low Mg 2+ (5). C3, Faster-sweep records of segments underlined in C2. C4, Faster-sweep records of segment underlined in C3.
