Light Reveals Neuron Function (photonics.com | Sep 2009 | News and Features)

BERKELEY, Calif., Sept. 17, 2009 – With a flash of light, scientists have zeroed in on the type of neural cell that controls swimming in larval zebra fish.

Using innovative light-activated proteins and gene expression techniques, the scientists from Lawrence Berkeley National Laboratory and the University of California, Berkeley, zapped several zebra fish with a pulse of light and initiated a swimming action in a subset of fish that was traced back to the neuron that drives the side-to-side motion of their tail fins.
