A UCSF study has revealed new
information about how the brain directs the body to make movements. The key
factor is "noise" in the brain’s signaling, and it helps explain why all
movement is not carried out with the same level of precision.
Understanding where noise arises in the brain has implications for
advancing research in neuromotor control and in developing therapies for
disorders where control is impaired, such as Parkinson’s disease.
The new study was developed "to understand the brain machinery behind such
common movements as typing, walking through a doorway or just pointing at an
object," says Stephen Lisberger, PhD, senior study investigator who is director
of the W.M. Keck Center for Integrative Neuroscience at the University of
California, San Francisco. Study co-investigators are Leslie C. Osborne, P
A. By sending signals to the muscles directly.
B. By sending nerve cells to the muscles.
C. By creating different nerve circuits.
D. By combining the electrical activity of neurons.
