Moreover, both caudal carotid artery sensors (Channels #3 and #4) demonstrated highly significant (p < 0.001) increases in firing frequency during the first interval of 0–20%, while the rostral sensors (Channels #1 and #2) also captured increased firing, but to a lesser degree than the caudal sensors (Channels #3 and #4) (p < 0.05) (Fig. 4 ).
