Figure 8.

Chx10 neurons are sparsely synaptically and electrically coupled to other Chx10 neurons. A1, Current step files of paired recordings of two Chx10 neurons with the same firing properties (tonic firing). Note that there is no sign of either synaptic or electrical coupling. A2, Same neurons as in A1 during locomotor-like activity at resting potentials (no currents injected). Neurons are rhythmically active in phase with each other. B1, Paired recordings from a phasic Chx10 neuron and a single spike firing Chx10 neuron. There is no sign of either synaptic or electrical coupling. B2, Paired recordings from the same neurons shown in B1 during locomotor-like activity. Both cells are rhythmically active in phase with each other. C1, D1, Average response of cell 2 to 50 trials of current-evoked spikes in cell 1. Cell 1 and cell 2 in C correspond to the cells shown in A and D corresponds to B. C2, D2, Average response of cell 1 to 50 trials of current-evoked spikes in cell 2.
