Goal-based prosthetic readout

Friday, July 9th, 2004

In this week’s Science, Richard Andersen’s lab shows the first use of a region (relatively) distant from primary motor areas for brain readout in a reaching task. Using a very small number of neurons (8-16 cells), the investigators were able to achieve a 60-70% accuracy in predicting reach movements to a particular target (out of 8 total targets). Read on for the abstract or here for the full article.

Cyberkinetics starting human trials

Sunday, April 11th, 2004

Looks like John Donoghue’s company will be doing human trials this year in quadraplegics! Cyberkinetics is one of the first companies (Neural Signals Inc. was the first, I think) to actually do human implants for read-out (versus other therapeutics like deep brain stimulation.

What’s really remarkable here is the speed at which research has moved to medicine. (the nature paper is from 2002!) This is how things should be.
