Key players responsible for learning and memory formation uncovered

One of the most fascinating properties of the mammalian brain is its capacity to change throughout life. Experiences, whether studying for a test or experiencing a traumatic situation, alter our brains by modifying the activity and organization of specific neural circuitry, thereby modifying subsequent feelings, thoughts, and behavior. These changes take place in and among synapses, communication junctions between neurons. This experience-driven alteration of brain structure and function is called synaptic plasticity and it is considered the cellular basis for learning and memory. Researchers have now identified a novel signaling system controlling neuronal plasticity.
