Mind reading: Researchers observe moment a mind is changed

mind reading

Researchers studying how the brain makes decisions have, for the first time, recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. The findings result from experiments led by electrical engineering Professor Krishna Shenoy, whose Stanford lab focuses on movement control and neural prostheses – such as artificial arms – controlled by the user’s brain.

The impact of powered prosthetic failures on the user

Prosthetics have come a long way in a relatively short amount of time. With the ongoing wars in the middle east the need for better prosthetics technologies has become more apparent, to this end we now have prosthetics that will allow a person to “feel”, we even have motorized prosthetics that will help allow a more fluid walk, but while powered lower limb prosthetics hold promise for improving the mobility of amputees, errors in the technology may also cause some users to stumble or fall. Because of this, new research examines exactly what happens when these technologies fail, with the goal of developing a new generation of more robust powered prostheses.
