Brain networks are groups of nerve cells, called neurons, which send information throughout the brain. Researchers linked increases in functional connectivity in certain brain regions to clinical symptoms of hyperactivity and restlessness, suggesting that inefficiencies in brain network processing could explain some symptoms of ADHD.

Diffusion tensor images (DTI) showed reduced structural integrity in the white matter fibers connecting the two areas, while a second type of image that maps brain activity, a functional magnetic resonance image (fMRI), showed less coordinated activity between the vmPFC and the amygdala. Puberty appears to be a specialized stage of development in which males and females are more likely to explore novel environments, Hodes says.

Like the amygdala, it assists in emotional learning and fear conditioning (Beaver 2009). In imaging studies of people with ADHD, there is an imbalance in the way that some brain networks are structured, which is called structural connectivity. Differences in behavior and corresponding brain activity were found between psychopaths and nonpsychopaths, after adjusting for group differences in severity of prior illicit drug use. Because its the choices of psychopaths that cause so much trouble, weve been trying to understand what goes on in their brains when they make decisions that involve trade-offs between the costs and benefits of action.
