New York, Nov 2 (THAINDIAN NEWS) A new research has revealed that a particular protein at the portion of the brain where fear is recalled from, is responsible for recalling bad experiences. As a result, the researchers claim that if that particular protein was removed from that portion of the brain, it permanently deletes the traumatic experience.

The study which was carried out on mice will be published in Science Express this week. The scientists used sound to induce fear in the mice and studied the part of the brain that is known to handle fear. The scientists discovered that particular cells at that of the brain showed more activity when the animals were exposed to higher sound.

The scientists then narrowed their research on the molecular structure of the part of the brain that was involved with fear. When they viewed the proteins in the nerve cells, they discovered that particular proteins in the nerve cells were temporarily increased. The protein level peaked in 24 hours before it completely disappeared in 48 hours. The protein, calcium-permeable AMPARs was found to be responsible for the retention of fear memory and when that particular protein was removed from the rats, the rats recovered from the fear more quickly.

The National Institutes of Health and the Howard Hughes Medical Institute funded the research.
