Rich rewards: ADHD medication’s effect on the brain

Methylphenidate may boost norepinephrine levels in the prefrontal cortex, which in turn regulates dopaminergic neurons firing in the striatum, when a reward is delivered. The study sheds new light on how medications for ADHD affect the reward system in the brain.

Are bigger brains better?

Greater hippocampal volume is not always a reliable predictor of learning and memory ability in older adults. Faster learning was only found in older adults who had both greater hippocampal volume and more uniform white matter connections to other parts of the brain.

Surprising effects of oxytocin on cocaine addiction

In men with a history of childhood trauma, oxytocin reduced the activity within the amygdala and cravings for cocaine. Women who were addicted to cocaine and had experienced childhood trauma showed an increase in amygdala activity following exposure to oxytocin.

Calculated surprise leads to groundbreaking discovery in cognitive control research

The activity of the dorsal anterior cingulate cortex (dACC) during motivated control reflects the calculation of surprise. The findings take cognitive control research to new heights by providing insight into how the dACC works as a component of a brain network that supports motivated behaviors.
