Ritalin Drives Greater Connection Between Brain Areas Key to Memory and Attention

Neuroscience NewsDecember 13, 2018

A new neuroimaging study reveals methylphenidate, better known as Ritalin, increases the level of dopamine available in the caudate. Along with increased dopamine levels, researchers also notice greater functional connectivity between the prefrontal cortex, hippocampus and precuneus, three areas of the brain associated with memory and attention....
