|Getting a Grip|

What does your brain tell your hand when you want to pick up an object?
Brown neuroscientists believe they now have a firmer grasp on the
The breakthrough, scientists say, could lead to better brain-computer interfaces for providing severely paralyzed people with a way to control robotic arms and hands using only their thoughts. Vargas-Irwin says demonstrating that the brain can produce a variety of activity patterns and still arrive at an appropriate grip plan suggests the brain is flexible enough to handle a wide variety of object contexts and can do so with a local network of neurons.
The findings were reported in the Journal of Neuroscience.
