CO2 laser emitted radiant heat pulses of 20 ms duration were used to activate predominantly slowly conducting nociceptive cutaneous afferents in man. Stimuli of two-fold individual pain threshold caused stinging and burning pain and elicited cerebral potentials with latencies consistent with A delta-fibre activity. After preferential block of the myelinated nerve fibres by pressure only the burning pain remained with significantly increased reaction time (about 1433 ms). The A delta-fibre… CONTINUE READING
