Production of Threshold Levels of Conscious Sensation by Electrical Stimulation of Human SomatosensTHE PRESENT WORK is part of a more general investigation into neuro-physiological activities of the cerebral cortex which may be involved in the elaboration or mediation of conscious sensation. The primary concern in these studies is the dynamics of the processes involved, rather than their topographical representation.

The problems susceptible to investigation can be much broader than the initial classical one of the topographical relations of cortical sites to the body sites of the subjectively referred sensations, and some of these problems will be considered in this article.

Cortical Representation of Evoked Potentials Relative to Conscious Sensory Responses, and of Somatotive response. The clearest example of this is seen in the responses to certain muscle afferents. Group I muscle afferents have been found to elicit evoked responses in primary somatosensory or closely related cortex (Amassian and Berlin, 1958; Oscarsson and Rosen, 1963, 1966; Albe-Fessard, 1967; Sw

A subdural stimulus to primary somatosensory cortex (S I) initiates an input different in its entry path and pattern from that generated by a peripheral sensory stimulus. Nevertheless, we have found it possible to elicit conscious sensory experiences with natural-
