RedTracker| Researchers have identified a brain protein BDNF involved in remodeling the brain under stress. When normal mice brains are exposed to chronic stress, dendrites shrink in overall volume and the amount of BDNF to enhance brain plasticity. In this case, researchers studied mice that had only one of two copies of the BDNF gene.
The same researchers recently identified that a variant of the BDNF gene is a likely contender for a role in premenstrual disorders, changing mice’s performance on certain memory tasks according to their stage of the estrous cycle. via Science Daily
