Tactile remapping: from coordinate transformation to integration in sensorimotor processing
Tactile localization entails the transformation of the initial skin-based location into an
external reference frame that accounts for body posture and subsequent flexible integration …

Using time to investigate space: a review of tactile temporal order judgments as a window onto spatial processing in touch
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 …

Towards explaining spatial touch perception: Weighted integration of multiple location codes
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 …

Dynamic tuning of tactile localization to body posture
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 …

Flexibly weighted integration of tactile reference frames
To estimate the location of a tactile stimulus, the brain seems to integrate different types of
spatial information such as skin-based, anatomical coordinates and external, spatiotopic …

Integration of anatomical and external response mappings explains crossing effects in tactile localization: A probabilistic modeling approach
To act upon a tactile stimulus its original skin-based, anatomical spatial code has to be
transformed into an external, posture-dependent reference frame, a process known as tactile …

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 …

The sensitive period for tactile remapping does not include early infancy
E Azañón, K Camacho, M Morales… - Child …, 2018 - Wiley Online Library
Visual input during development seems crucial in tactile spatial perception, given that late,
but not congenitally, blind people are impaired when skin‐based and tactile external …

No evidence for a role of spatially modulated α-band activity in tactile remapping and short-latency, overt orienting behavior
Oscillatory α-band activity is commonly associated with spatial attention and multisensory
prioritization. It has also been suggested to reflect the automatic transformation of tactile …
