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

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.

Cannabidiol Shows Sustained Effects Against Depression for Seven Days: Rat Study

A study using rat models of depression reveals a single dose of the cannabis extract CBD can help to reduce symptoms of depression for up to one week. Researchers say cannabidiol appears to activate mechanisms that help repair neural circuitry in the prefrontal cortex and hippocampus, which get damaged as a result of depression.
