Does the crossed-limb deficit affect the uncrossed portions of limbs?
When locating touch, we remap its location from skin-based to external coordinates as a
function of body posture. While remapping is thought to occur whenever there is tactile input …

Spatial remapping of touch: confusion of perceived stimulus order across hand and foot
T Schicke, B Röder - … of the National Academy of Sciences, 2006 - National Acad Sciences
The “body schema,” a spatial representation of the body in its environment, has been
suggested to be an emergent property of a widespread network of effector-specific frontal …

A three-dimensional spatial characterization of the crossed-hands deficit
To perceive the location of touch in space, we integrate information about skin-location with
information about the location of that body part in space. Most research investigating this …

[HTML][HTML] More than skin-deep: Integration of skin-based and musculoskeletal reference frames in localization of touch.
The skin of the forearm is, in one sense, a flat 2-dimensional (2D) sheet, but in another
sense approximately cylindrical, mirroring the 3-dimensional (3D) volumetric shape of the …

External location of touch is constructed post-hoc based on limb choice
When humans indicate on which hand a tactile stimulus occurred, they often err when their
hands are crossed. This finding seemingly supports the view that the automatically …

Integration of hand and finger location in external spatial coordinates for tactile localization.
Tactile stimulus location is automatically transformed from somatotopic into external spatial
coordinates, rendering information about the location of touch in three-dimensional space …

Reach trajectories characterize tactile localization for sensorimotor decision making
J Brandes, T Heed - Journal of Neuroscience, 2015 - Soc Neuroscience
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 …

Expansion of perceptual body maps near–but not across–the wrist
MR Longo - Frontiers in Human Neuroscience, 2017 - frontiersin.org
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 …

Visuoproprioceptive conflict in hand position biases tactile localization on the hand surface.
The location of touch can be represented in a somatotopic reference frame and, combined
with proprioceptive information, in an external reference frame. There is evidence that body …

Implicit body representations and tactile spatial remapping
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 …
