Brain-wide map links fruit fly behaviors to neurons

by  /  21 May 2014

Triggering neuron activity with flashes of light allows scientists to tie behaviors in fruit fly larvae to specific neuron groups, reports a study published 25 April in Science. The study catalogs the associations between neurons and the movements they control.

Miniature cable reads a mouse’s sense of reward

by  /  20 November 2013

A tiny fiber-optic probe inserted into the reward center of the mouse brain monitors how the mouse feels about meeting a peer — or a golf ball. The unpublished technique was presented last week at the 2013 Society for Neuroscience annual meeting in San Diego.

Activity in cerebellum silences seizures in mice

by  /  10 November 2013

Activating cells in the cerebellum, a brain region usually associated with movement, eliminates seizures in a mouse strain that normally has hundreds of seizures a day, according to results presented Saturday at the 2013 Society for Neuroscience annual meeting in San Diego.

Light toggles function of signaling proteins

by  /  1 May 2013

Researchers can use light to activate certain proteins that receive signals at the junctions between neurons and that are key targets for fragile X syndrome therapies, according to a study published in the April issue of Nature Neuroscience.
