Figure 32

Turtle ganglion-cell mean impulse latencies for three synaptic pathways from photoreceptors to ganglion cells: OFF responses from red cones (red), OFF responses from rods (blue), and ON responses from red cones. Electrical currents injected directly into rods or cones generated responses. OFF responses were measured from the offset of hyperpolarizing steps (break) or the onset of depolarizing steps (make), and conversely for ON responses. Hatched cells could not be driven antidromically, fired only one impulse, and may be amacrine cells. Current pulses were 400-900 msec long. Reproduced from Baylor and Fettiplace (99).
