Researchers at the University of North Carolina and the National Institutes of Health (NIH) have perfected a noninvasive ‘chemogenetic’ technique that allows them to switch off a specific behaviour in mice, such as voracious eating, and then switch it back on. The method works by targeting two different cell surface receptors of neurons that are responsible for triggering the specific chemical signals that control brain … Continue reading New chemogenetic tool is the first to target different kinds of receptors on a neuron sequentially.
