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.

New molecules help researchers orchestrate brain activity

by  /  12 March 2014

Using newly discovered molecules from algae, researchers can control the activity of two families of neurons in a single mouse or fly, they reported 9 February in Nature Methods.

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 The unpublished technique was presented last week at the 2013 Society for Neuroscience annual meeting in San Diego.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.

New method uses light to toggle gene expression

by  /  25 September 2013

Researchers have modified optogenetics — a technique that activates neurons in mouse brains with beams of light — to toggle a gene on or off. They reported the advance 22 August in Nature.


Molecular mechanisms: Oxytocin boosts brain signals

by  /  10 September 2013

Oxytocin may enhance brain signaling by increasing the strength of the signals and minimizing background noise, according to a study published 4 August in Nature.

Genetic switch labels active neurons in mouse brains

by  /  28 August 2013

A new method, described 5 June in Neuron, allows researchers to tag only those neurons that are active during the following 12-hour time window.

Researchers reveal obsession circuits in the brain

by  /  27 June 2013

Researchers can shut down or trigger compulsive behaviors in mice by using light to target certain brain circuits, according to two studies published 7 June in Science.

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.
