Researchers discover 'anxiety cells' in brain

US neuroscientists have recognized "nervousness cells" in the brains of mice, clearing route for a potential treatment for people experiencing uneasiness issue.
They found the phones inside a structure called the hippocampus. Be that as it may, the cells most likely likewise exist in people, said Rene Hen, from Columbia University Irving Medical Center (CUMC) in the US.
The hippocampus assumes an outstanding part in the cerebrum's capacity to shape new recollections and to help creatures - from mice to people - explore through complex conditions.
"We call these nervousness cells since they just fire when the creatures are in places that are intrinsically terrifying to them," Hen said.
"For a mouse, that is an open region where they are more presented to predators, or a hoisted stage," Hen said.
The terminating of the tension cells sends messages to different parts of the cerebrum that turn on edge practices, in mice, those incorporate evading the unsafe territory or escaping to a sheltered zone, as per an examination distributed in the diary Neuron.
In spite of the fact that numerous different cells in the mind have been recognized as assuming a part in nervousness, the cells found in this examination are the main known to speak to the condition of tension, paying little heed to the kind of condition that incites the feeling.
By killing the nervousness cells and on utilizing a method called optogenetics that enables researchers to control the action of neurons utilizing light emissions, the analysts found that the tension cells control uneasiness practices.
At the point when the phones were hushed, the mice quit delivering dread related practices, meandering onto hoisted stages and far from defensive dividers.
At the point when the tension cells were fortified, the mice displayed more dread practices notwithstanding when they were in "safe" environment.
"This is energizing since it speaks to an immediate, fast pathway in the cerebrum that gives creatures a chance to react to tension inciting places without expecting to experience higher-arrange mind locales," said Mazen Kheirbek, from the University of California, San Francisco in the US.
"Since we have discovered these phones in the hippocampus, it opens up new zones for investigating treatment thoughts that we didn't know existed previously," said Jessica Jimenez from CUMC
