The new discovery by scientists from the University of Columbia will help to treat post-traumatical stress disorders (PTSD).

A group of scientists supervised by Attila Losonczy, discovered neurons, which inhibit the formation of fearful in hippocampus. The opening researchers published in the journal Science, writes Daily Mail.

Experiments on mice showed, that the so-called inhibitory neurons guarantee, that neutral memories about a certain place will not be «contaminated» with a bad memory, happened in the same time.

Researchers found inhibitory cells – so-called interneurons, that are responsible for formation of scary memories in hippocampus. They act like a filter and can block unwanted information associated with this traumatic event. When the inhibitory neurons were deactivated in rodents, the mice stopped showing jitters in a setting, that corresponded to a certain negative event.
