  • Title: Touch and the body.
    Author: Serino A, Haggard P.
    Journal: Neurosci Biobehav Rev; 2010 Feb; 34(2):224-36. PubMed ID: 19376156.
    Abstract:
    The dual nature of touch has long been understood. The sense of touch seems to carry information at the same time about the external object touching our skin, and also about our body itself. However, how these two interact has remained obscure. We present an analytic model of how tactile information interacts with mental body representations in the brain. Four such interactions are described: the link between the body surface and the maps in primary somatosensory cortex, the contribution of somatosensory cortical information to mental body representations, the feedback pathway from such higher representations back to primary tactile processing in somatosensory cortex, and the modulation of tactile object perception by mental body representations.
