TEMPORAL DISPERSION IN CORTICAL RESPONSE

Abstract
The cerebral representation of certain forms of deep somatic sensibility was mapped in the marsupial phalanger (Trichosurus vulpecula) and the rabbit This deep sensibility appears to be represented bilaterally in somatic area I in phalanger and rabbit, with the ipsilateral representation of each limb concentric with and only slightly smaller than the contralateral. Latency studies of the responses suggest that perception and localization may occur in terms of the disposition of the point of shortest latency within an activated area of essentially constant site and dimensions.
