Offset peaks and troughs simply interpreted as evidence for a functional connection among RTN-pF neurons (top) and from Böt-VRG→RTN-pF neurons (bottom) tested with either central chemoreceptor or baroreceptor stimulation. Arrows indicate initial firing rate changes in trigger (left) and target (right) neurons in response to presented stimulus. Numbers of offset peaks and troughs detected are tabulated (e.g., 2 peaks and 4 troughs were detected in correlograms in which both the trigger and target cells were RTN-pF neurons that responded with an increased firing rate to central chemoreceptor stimulation; 1 peak and 1 trough were detected for RTN-pF pairs whose constituent neurons responded to baroreceptor stimulation with an increased firing rate).
