Aδ nociceptor response to laser stimuli: Selective effect of stimulus duration on skin temperature, brain potentials and pain perception

Abstract:

Objective: To disclose a possible effect of duration of pulsed laser heat stimuli on Aδ nociceptor responses, skin temperature profiles, brain evoked potentials and pain perception. Methods: We used a laser stimulator which works in the millisecond range and allows us to change the duration of the pulse while keeping the total energy of the stimulus constant. In 10 healthy volunteers, we measured the intensity of perceived pain with a 0-10 scale and the latency and amplitude of the early N1 a...
