optogenetics

A set of galanin producing nerve cells, located in a region of the hypothalamus called the ventrolateral preoptic nucleus (VLPO), are essential to normal sleep, research from Beth Israel Deaconess Medical Center has found. The study build on work from two decades ago, when Clifford B. Saper, MD/Ph.D., Chairman of the Department of Neurology at… Read more

What Is Chemogenetics?

Chemogenetics is the processes by which macromolecules can be engineered to interact with previously unrecognized small molecules. Chemogenetics as a term was originally coined to describe the observed effects of mutations on chalcone isomerase activity on substrate specificities in the flowers of Dianthus caryophyllus. This method is very similar to optogenetics however, it uses chemically… Read more

A special population of nerve cells in the skin that are responsible for sensitivity to gentle touch in patients with neuropathic pain has been identified by scientists from European Molecular Biology Laboratory Rome. For patients with neuropathic pain, a chronic condition affecting 7 to 8 percent of the European population, extreme pain and sensitivity are… Read more

A mother’s instinct to snatch up her wandering offspring and return them to the nest depends on a specific set of brain cell signals, new research in mice indicates. NYU School of Medicine scientists traced the roots of this behavior to brain cells that make the signaling chemical dopamine, release of which is known to… Read more

Specially crafted, ultrafast pulses of light can trigger neurons to fire, and could someday help patients with light-sensitive circadian or mood problems, a new study from the University of Illinois reports. Chemists have used such carefully crafted light beams, called coherent control, to regulate chemical reactions, but this study is the first demonstration of using… Read more
