The 2003 paper proposing signaling imbalance in autism

by ,  /  26 February 2013

In 2003, John Rubenstein and Michael Merzenich first described the theory, now popular in autism, that the disorder reflects an imbalance between excitation and inhibition in the brain. Takao K. Hensch and Parizad M. Bilimoria review the paper and its impact on the field.

Radio waves turn on gene expression

by  /  6 June 2012

The heat produced by radio waves can interact with metallic nanoparticles bound to temperature-sensitive ion channels in cells, allowing researchers to remotely alter gene expression in live animals, according to a study published 4 May in Science. The technique could also be used to activate neuronal signals by manipulating calcium influx into neurons, the researchers say.

Chili pepper protein can alter behavior of mice

by  /  18 April 2012

By manipulating the location of a protein that detects capsaicin, the molecule responsible for the burn in hot chili peppers, researchers can activate subpopulations of neurons and alter the behavior of mice. The results were published 20 March in Nature Communications.
