A 'traffic light' for neurons means 'go' for improving brain research

Every thought, feeling and action originates from the electrical signals emitted by diverse brain cells enmeshed in a tangle of circuits. At this fundamental level, scientists struggle to explain the mind. Worse yet, they have lacked tools to understand what's going wrong in patients with ailments such as depression or Parkinson's disease. New Stanford-led research published in the April 5 issue of Nature describes a technique to directly control brain cell activity with light. It is a novel means for experimenting with neural circuits and could eventually lead to therapies for some disorders.
