Body integrity dysphoria (BID) is a brain-based disorder characterized by a persistent, obsessing and disturbing desire for the amputation of healthy limbs. Importantly, individuals with BID are adamant about which specific body segment the...

Also, dynamic touch given by a human hand invoked a supralinear enhancement of pupil dilation indicating that the combination of these two features induced a stronger autonomic activation than the summed effects of each separately.

Decoupling dynamic touch signals in the optical tactile sensors is highly desired for behavioral tactile applications yet challenging because typical optical sensors mostly measure only static normal force and use imprecise multi-image averaging for dynamic force sensing....Here, we report a highly sensitive upconversion nanocrystals-based behavioral biometric optical tactile sensor that instantaneously and quantitatively decomposes dynamic touch signals into individual components of vertical normal and lateral shear force from a single image in real-time.

A self-powered mechanoreceptor array is demonstrated using four mechanoreceptor cells for recognition of dynamic touch gestures. Each cell consists of a triboelectric nanogenerator (TENG) for touch sensing and a bi-stable resistor (biristor) for spike encoding.

The purpose of the present study was to compare dynamic touch (CTs activated) to static touch (CTs less activated) during a babywearing procedure among infants experiencing Neonatal Opioid Withdrawal Syndrome (NOWS)....Each day infants alternated (randomly) in a static touch (hands-free babywearing) or dynamic touch condition (stroking the top of the infants' head at a velocity of 3 cm/s while babywearing). On average, infants completed 3 dynamic and 3 static babywearing sessions....These effects were significantly stronger during the dynamic touch condition (reduction in HR of 11.17 bpm) compared to the static touch condition (reduction in HR of 3.74 bpm). These effects did not significantly vary by wearer (mother, father, volunteer)....There was evidence for a calming effect among caregivers as well, particularly in the dynamic touch condition, when caregivers were engaged in active touch.

Four categories were identified: 1) Deep and dynamic touch pressure from the plastic balls induced calmness; 2) Changing sensory impressions from the rolling balls distracted attention from distressing thoughts and emotions; 3) The ball blanket improved the quality and quantity of sleep, which increased

Sensory systems are shaped in postnatal life by the refinement of synaptic connectivity. In the dorsal horn of the spinal cord, somatosensory circuits undergo postnatal activity-dependent reorganization, including the refinement of primary ...

Here, a machine learning (ML)-guided design of flexible tactile sensor system is reported, enabling a high classification accuracy (≈99.58%) of tactile perception in six dynamic touch modalities.

These findings support a unified model for dynamic touch in which mechanical stimuli stretch hundreds to thousands of axon protrusions across an end organ, opening proximal, axonal Piezo2 channels and exciting the neuron.

As observed for static touch in alpha band and for dynamic touch in theta band, the number of common connections between the two hands was decreased by increasing the surface roughness.
