Now Closer To Reality: Prosthetics That Can Feel

Humans do a lot of things with their hands: We squeeze avocados at the grocery story, scratch our dogs behind the ears and hold our significant others’ hands. They are things that many people who have lost limbs can’t do. Biomedical engineer Jacob Segil at the University of Colorado at…Continue readingNow Closer To Reality: Prosthetics That Can Feel

Misfiring From Jittery Neurons Sets Fundamental Limit On Perception

Stanford researchers have helped solve a longstanding mystery about how brains manage to process information so accurately, despite the fact that individual neurons, or nerve cells, act with a surprising degree of randomness. The findings[1] offer new insights into the limits of perception and could aid in the design of…Continue readingMisfiring From Jittery Neurons Sets Fundamental Limit On Perception

Robot Body Surrogates Help People With Profound Motor Impairments

An augmented reality interface system could help people with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks. Such tasks might include feeding and performing routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a…Continue readingRobot Body Surrogates Help People With Profound Motor Impairments

Texture Identity Is Encoded In Cortical Neuron Response

Information about texture is transmitted from sensors in the skin and through the nerves to the somatosensory cortex, the part of the brain responsible for interpreting the sense of touch. New research by neuroscientists at the University of Chicago shows that as neurons in this part of the brain process…Continue readingTexture Identity Is Encoded In Cortical Neuron Response

Dorsal Laryngeal Motor Cortex Controls Voice Pitch

A human brain area that regulates vocal pitch in both speech and song has been identified in new research by UC San Francisco scientists. Insights into pitch control could pave the way for advanced brain prosthetics that could allow people who can’t speak to express themselves in a naturalistic way.…Continue readingDorsal Laryngeal Motor Cortex Controls Voice Pitch

Controlling Robots With Brainwaves And Hand Gestures

Getting robots to do things isn’t easy: Usually, scientists have to either explicitly program them or get them to understand how humans communicate via language. But what if we could control robots more intuitively, using just hand gestures and brainwaves? A new system spearheaded by researchers from MIT’s Computer Science…Continue readingControlling Robots With Brainwaves And Hand Gestures

Artificial Sensory Nerve Circuit Identifies Braille Letters

An artificial sensory nerve system that can identify letters in the Braille alphabet and activate the twitch reflex in a cockroach has been developed by Stanford and Seoul National University researchers. The work is a step toward creating artificial skin for prosthetic limbs, to restore sensation to amputees and, perhaps,…Continue readingArtificial Sensory Nerve Circuit Identifies Braille Letters
