Inhibiting certain brain cells sharpens animal's response to small and quick visual stimuli Between alerting us to danger and allowing us to spot prey, vision keeps many animals, including humans, alive. But exactly how does this important sense work, and why is it easier for us to spot movement of small objects in our field of vision, than to notice other things? The complexity of the neural network that supports vision has long baffled scientists. Now, with a new technology and support from...

Technique targeting light-gated channels to enigmatic neurons proves role in burst swimming A new way to select and switch on one cell type in an organism using light has helped answer a long-standing question about the function of one class of enigmatic nerve cells in the spinal cord. Through targeted insertion of light-sensitive switches into these cells in awake zebrafish larvae, University of California, Berkeley, and UC San Francisco scientists have found that these mysterious cells...
