Brain plasticity restored in adult mice through targeting specific nerve cell connections

Research in mice finds a new molecular mechanism that is essential for maturation of brain function and may be used to restore plasticity in aged brains. Unlike previous research that broadly manipulated brain plasticity and affected the entire brain, this work targets for the first time a specific molecule acting on a single type of neuronal connection to modulate brain function. The findings may advance treatment of human diseases such as autism and stroke.
