Scientists find brain cells that are responsible for anxiety

Good news for anyone with an anxiety disorder: Neuroscientists have revealed that a specific brain cell group has been located that are being called "anxiety cells." Scientists now believe it is possible to control the action of these neurons so that the symptoms of anxiety are reduced.

The research, originally published in the journal Neuron, was conducted using a technique known as calcium imaging. Basically, miniature microscopes were installed in the brains of mice to record daily activity in the hippocampus region of mice.

When stressed, it was possible to observe high levels of activity of the ventral hippocampus of rats, with specific neurons in action. According to psychiatry professor Rene Hen, this same mechanism must also occur in humans.

The analysis of the brain activities of the mice allowed not only the identification of these anxiety-related neurons, but also a way to control the action of these brain cells.

Good news!

The control, in this case, occurred through optogenetics, a process that works with light beams that are able to interrupt the activity of these cells that promote anxiety.

The mice that underwent this treatment began to act less fearfully and became bolder - in their case, anxiety was triggered by the fear that a predator might present themselves, but when subjected to optogenetics, the animals would move around. more broadly, in open spaces, without fear of predators.

Moderate doses of anxiety are helpful and even necessary. They are what make us escape dangerous situations, such as running in the opposite direction of an uncontrolled car. The problem is when anxiety is too intense and constant - it is no wonder that anxiety disorders are becoming more and more worrisome.

The study's lead author, Jessica Jimenez, believes that now that these cells have been localized, it will be possible to explore new treatments for anxiety, following paths that have not yet been explored. Will take!
