Tactile discrimination performance depends on the receptive field (RF) size of
somatosensory cortical (SI) neurons. Psychophysical masking effects can reveal the RF of …

Viewing the body can improve tactile perception. We investigated whether this could be due
to a remodeling of somatosensory cortical areas during vision of the body. Single‐pulse …

Over 150 years ago, EH Weber [1] declared that experience showed that tactile acuity was
not affected by viewing the stimulated body part. However, more recent investigations …

We report two experiments in which non-informative vision of the finger enhanced tactile
acuity on the fingertip. The right index finger was passively lifted to contact a grating. Twelve …

Research on sensory perception now often considers more than one sense at a time. This
approach reflects real-world situations, such as when a visible object touches us. Indeed …

Previous research has demonstrated that vision of a body site, without proprioceptive
orienting of eye and head to that site, could affect tactile perception. The body site viewed …

Masking effects have been demonstrated in which tactile sensitivity is affected when one
touch is close to another on the body surface. Such effects are likely a result of local lateral …

Detection of a tactile stimulus on one finger is impaired when a concurrent stimulus (masker)
is presented on an additional finger of the same or the opposite hand. This phenomenon is …

A multitude of events bombard our sensory systems at every moment of our lives. Thus, it is
important for the sensory and motor cortices to gate unimportant events. Tactile suppression …

Perception of our own bodies is based on integration of visual and tactile inputs, notably by
neurons in the brain's parietal lobes. Here we report a behavioural consequence of this …
