“…The current findings broadly agree with previous research which has reported reduced N2-P2 amplitudes elicited by intracutaneous stimulation of the finger during artificial stimulation of the baroreceptors using neck suction (Mini et al, 1995;Angrilli et al, 1997). In addition, the current data are in line with reports of dampened lower limb nociceptive flexion reflex responding during systole compared to diastole (Edwards et al, 2001;Edwards et al, 2002;Edwards et al, 2003;McIntyre et al, 2006).…”

Evidence suggests that the arterial baroreceptors modulate pain. To examine whether cortical processing of nociception is modulated by natural variations in arterial baroreceptor stimulation during the cardiac cycle, peak-to-peak amplitudes of the N2-P2 pain-related potential and pain ratings were recorded in response to noxious laser stimulation at different times during the cardiac cycle in 10 healthy males. Significant variations in the N2-P2 amplitudes occurred across the cardiac cycle, with smaller amplitudes midcycle, indicating that cortical processing of nociception was attenuated during systole compared to diastole. Pain ratings did not vary across the cardiac cycle.These data support the hypothesis that arterial baroreceptors modulate the processing of nociception during each cardiac cycle.

“…Angrilli et al (1997) found reduced subjective pain intensity during baroreceptor stimulation in subjects with blood pressures at the higher end of the normotensive range, whereas no such effect was found for individuals with lower blood pressure. Pain-related EEG potentials were also reported to decrease during baroreceptor stimulation in individuals with higher, though not lower blood pressure values Brody et al, 1997).…”

“…Indeed, arterial baroreceptors, in addition to their well-known cardiovascular homeostatic role, are able to inhibit cortical arousal (Rau, Pauli, Brody, Elbert, & Birbaumer, 1993), pain perception (Angrilli, Mini, Mucha, & Rau, 1997) and spinal reflex amplitude (Dworkin et al, 1994). However, the study of such mechanisms is matter of more focused future research.…”
