Abstract
Raphe magnus cells that are inhibited by skin pinching fire spontaneously with strongly preferred interspike intervals (mean cycle 85 ms, n = 33). In pentobarbital-anesthetized rats, mid-cycle cathodal activation (0.3 ms) or end-cycle anodal block (30-60 ms) at ~ 1 Hz through the extracellular recording microelectrode delayed expected spikes; respective post-stimulus latencies peaked on avarage at 1.17 (n = 14) and 0.40 (n = 6) cycles. Feedback inhibition following random excitation, but not free-running intrinsic or afferent oscillations, may therefore cause the rhythm.
