Ritalin Boosts Learning By Increasing Brain Plasticity

Posted Mar 08 2010 6:05pm

Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning.

In animal research, the scientists showed for the first time that Ritalin boosts both of these cognitive abilities by increasing the activity of the neurotransmitter dopamine deep inside the brain. Neurotransmitters are the chemical messengers neurons use to communicate with each other. They release the molecule, which then docks onto receptors of other neurons. The research demonstrated that one type of dopamine receptor aids the ability to focus, and another type improves the learning itself.

The scientists also established that Ritalin produces these effects by enhancing brain plasticity – strengthening communication between neurons where they meet at the synapse.  Research in this field has accelerated as scientists have recognized that our brains can continue to form new connections – remain plastic – throughout life.
