Touch is bound to the skin–that is, to the boundaries of the body. Yet, the activity of neurons
in primary somatosensory cortex just mirrors the spatial distribution of the sensors across the …

Localizing tactile stimuli on our body requires sensory information to be represented in
multiple frames of reference along the sensory pathways. These reference frames include …

Most animals must interact with spatially complex and dynamic environments in order to
survive. For example, an animal may navigate through a forest, carefully avoiding some …

Spatial target information for movement planning appears to be coded in a gaze-centered
reference frame. In touch, however, location is initially coded with reference to the skin …

Identifying the spatial location of touch on the skin surface is a fundamental function of our
somatosensory system. Despite the fact that stimulation of even single mechanoreceptive …

Perceiving the external spatial location of touch requires that tactile information about the
stimulus location on the skin be integrated with proprioceptive information about the location …

Spatial localization of touch is critically dependent upon coordinate transformation between
different reference frames, which must ultimately allow for alignment between somatotopic …

To respond to a touch, it is often necessary to localize it in space, and not just on the skin.
The computation of this external spatial location involves the integration of somatosensation …

To perceive the location of a tactile stimulus in external space (external tactile localisation),
information about the location of the stimulus on the skin surface (tactile localisation on the …

Localizing touch in space is essential for goal-directed action. Because body posture
changes, the brain must transform tactile coordinates from an initial skin-based …
