Scientists have found neurons that prevent mice from forming fearful memories in an area of the brain called the hippocampus.
These inhibitory neurons ensure that a neutral memory of a context or location is not contaminated by an unpleasant event occurring at the same time.
The team says their work could one day help them better understand the neural basis of conditions such as post traumatic stress disorder.
The study is published in Science.
Attila Losonczy, from Columbia University in New York and colleagues, were interested in how the hippocampus stores memories of a particular context and then separates this memory from a fearful event.
