Response of eleven interneurons to time delay in onset of leg stimulation. (a) Schematic presentation of leg stimulation configurations (left prothoracic/right prothoracic; left metathoracic/right prothoracic; left metathoracic/right metathoracic). Symbols in (a) indicating leg stimulation configurations match those in (b–d). (b) Responses of interneuron N1 to applied time delay between leg stimulation. N1 responded with three spikes per spike train, visible as three distinct clusters. The spike pattern changes when stimulation of dominant leg was delayed. (c) Changes in the response latency of 11 interneurons. (d) Effect of the applied time delay on the spike count. In (b–d) same colours and same symbols indicate the same neuron. Neurons, represented by black and grey colours were not successfully stained.
