Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.
Using piezoelectric materials, researchers have replicated the muscle motion of the human eye to control camera systems in a way designed to improve the operation of robots. This new muscle-like action could help make robotic tools safer and more effective for MRI-guided surgery and robotic rehabilitation.
Researchers developed an artificial cerebellum (a biologically-inspired adaptive microcircuit) that controls a robotic arm with human-like precision.
Nanotechnology scientists and memory researchers at the Kiel University redesigned a mental learning process using electronic circuits. The bell rings and the dog starts drooling. Such a reaction was part of studies performed by Ivan Pavlov, a famous Russian psychologist and physiologist and winner of the Nobel Prize for Physiology and Medicine in 1904. His […]
New method offers automated way to record electrical activity inside neurons in the living brain. Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, […]
New technology bypasses spinal cord and delivers electrical signals from brain directly to muscles. A new Northwestern Medicine brain-machine technology delivers messages from the brain directly to the muscles – bypassing the spinal cord – to enable voluntary and complex movement of a paralyzed hand. The device could eventually be tested on, and perhaps aid, […]
