Background Tactile discrimination, a cognitive task reliant on fingertip touch for stimulus
discrimination, encompasses the somatosensory system and working memory, with its acuity …

When ulnar nerve lesions happen above the wrist level, sensation recovery after acute
repair or nerve grafting is often challenging. Distal sensory nerve transfers may be an option …

Tactile sensitivity is affected by age, as shown by the deterioration of spatial acuity assessed
with the two‐point discrimination task. This is assumed to be partly a result of age‐related …

According to the predictive coding account, the attenuation of tactile perception on the hand
exposed to the visuo-tactile Rubber Hand Illusion (vtRHI) relies on a weight increase of …

Among other bodily signals, the perception of sensations arising spontaneously on the skin
with no external triggers contributes to body awareness. The topic of spontaneous …

Introduction and Purpose Knee osteoarthritis (OA) is a common condition that limits function
and reduces quality of life. Total knee arthroplasty (TKA) is a surgical procedure that …

Background The mechanical tactile stimulation, such as plastic pins and airflow-driven
membrane, induces cortical activity. The cortical activity depends on the mechanical tactile …

Abstract Two-point discrimination (2PD) test reflects somatosensory spatial discrimination
ability, but evidence on the relationship between 2PD and cortical gray matter (GM) volume …

Tactile perception is a complex phenomenon that is processed by multiple cortical regions
via the primary somatosensory cortex (S1). Although somatosensory gating in the S1 using …

Changes in α-band cortical oscillatory activity (8–13 Hz) affect perception; however, how
these changes in the left posterior parietal cortex (PPC) and primary somatosensory cortex …
