Brain-Controlled Cursor

Thought-Controlled Computer Cursor Takes a Leap Forward

Yahoo! Tech | September 28, 2015


Scientists working to perfect a thought-controlled computer cursor said Monday they have achieved their best results yet, and are moving closer to creating a version that paralysis victims can use.

The device works twice as fast as in previous trials after American developers found better ways to read brain activity and fine-tuned its hardware and software, according to results published in the journal Nature Medicine.

[Abstract: Neural prostheses have the potential to improve the quality of life of individuals with paralysis by directly mapping neural activity to limb- and computer-control signals. We translated a neural prosthetic system previously developed in animal model studies for use by two individuals with amyotrophic lateral sclerosis who had intracortical microelectrode arrays placed in motor cortex. Measured more than 1 year after implant, the neural cursor-control system showed the highest published performance achieved by a person to date, more than double that of previous pilot clinical trial participants.])>
