[-Somatosensory evoked potentials by acupunctural stimulus and cortical functional projection].

We studied the somatosenory evoked potentials elicited by punctual bipolar stimulation of acupunctural points, with great and little primary sensory cortex representation. We found that different quality signal was obtained, apparently related with the extent of such cortical representation, wich indicate a possible important role of the cortex on the repetitive somatosensory afference.
