Exogenous and endogenous components of ultralate (C-fibre) evoked potentials following CO2 laser stimuli to tiny skin surface areas in healthy subjects

CO2 laser stimulation of tiny skin surface areas on the hand dorsum generate ultralate laser evoked potentials (LEPs) with a major positivity maximal at the vertex at a latency of about 1 s. These potentials follow selective and direct activation of C-fibres in the superficial layers of the skin. To...
