Infrared laser stimulation

In 1975, Mor and Carmon introduced infrared laser stimulators as tools to explore nociception in humans. Allowing brief, synchronous, and selective activation of cutaneous Adelta- and C-fibre nociceptors, laser heat stimulators are now used extensively to study nociception in humans. Recently, we have collaborated to the development of a novel CO2 laser stimulator whose power is regulated using a feedback control based on an online measurement of skin temperature at the site of stimulation (Laser Stimulation Device, SIFEC, Belgium).
