Using minimally invasive brain implants, researchers evoked the sense of touch in patients who had lost tactile sensations. The technique could be used to restore tactile sensations to those with paralysis and neuropathy.
Regardless of receptor types, spiking patterns determine vibrotactile frequency perception. The findings challenge existing theories about how Pacinian receptor channels work together in response to vibrotactile stimulation.
A new neuroimaging study reveals brain activity is reduced when we experience self touch, as opposed to the touch of another person. The findings shed light on how the brain is able to distinguish between tactile sensations generated by the touch of another and personal touch.
