BCI Helps Paralyzed Users Feel Again

In a breakthrough study, researchers enabled brain-computer interface (BCI) users with tetraplegia to create personalized tactile sensations, marking a step toward restoring realistic touch. Unlike previous attempts where artificial touch felt generic, participants could adjust stimulation parameters to make digital objects—like a cat, apple, or key—feel distinct.

The Brain Combines Touch and Sound to Enhance Sensory Experiences

The inferior colliculus, a midbrain region known for sound processing, also plays a role in touch sensation by integrating tactile and auditory signals. Pacinian corpuscles, highly sensitive skin mechanoreceptors, relay high-frequency vibrations to this brain area, amplifying sensory experiences. This mechanism explains phenomena like feeling music vibrations during a concert and highlights the brain's adaptability in processing multisensory information.

Molecule Discovery Could Revolutionize Chronic Pain Treatment

Researchers have identified a natural molecule, phosphatidic acid, that reduces the sensitivity of touch-sensing ion channels, providing a promising new avenue for managing chronic pain. By increasing levels of this molecule, cells become less sensitive to touch, which was confirmed through tests on sensory neurons and in mice. This discovery could lead to more targeted and effective treatments for conditions involving inflammatory pain.

Illusory Touch: Creating Real Sensations with Phantom Vibrations

Researchers discovered the minimal distance required for a vibrating point to create a phantom sensation of movement on the skin. By placing two vibrotactile actuators on different skin locations, they demonstrated that people could feel an illusory moving point between them.

This shows a person with neurons over their skin.

Skin Speaks: Directing Nerve Growth for Sensation

Researchers found that the skin, not pre-existing genetic programming, instructs nerve cells on how to mature for specific sensory tasks. The findings showcase that skin cues determine whether nerve endings develop to detect sensations in hairy or hairless skin.

Touch and Sight Are Linked Before Birth

During the embryonic stage, tactile information simultaneously activated the tactile and visual neural pathways. After birth, the pathways separate and reorganize to allow for individual processing of visual and tactile information.
