A simple act such as rubbing your temples when you have a headache can help to alleviate pain. Researchers say this is because pain-responsive neurons in the brain quiet down when these neurons also receive touch input.
Researchers have identified a specific neural circuit and neuropeptide responsible for relaying the sensation of a pleasant touch from the skin to the brain.
A gene commonly associated with the sense of touch may also play an important role in the sense of smell, researchers report.
Researchers have revealed the 3d structure of the Flycatcher1 protein channel which enables the Venus flytrap to close in response to prey. The findings shed light on how other mechanosensitive ion channels may operate in other plants, bacteria, and the human body.
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.
Study points to the evolutionary and developmental similarities between sensory cells in the inner ear and skin.
