Understanding the Brain's Default Mode Network
22:32 - 33:01 (10:29)
The default mode network is the network of brain areas that are active when we're not doing anything, and it underlies our state of mind when we're not engaged in any specific task. According to brain imaging studies, treatment for ADHD and aging can cause the default mode network and the task networks to become anti-correlated again.

The release of dopamine in the brain narrows our focus on visual and auditory inputs, whereas the default mode network is the network of brain areas that become active when the brain is at rest.

Summary
The release of dopamine in the brain narrows our focus on visual and auditory inputs, whereas the default mode network is the network of brain areas that become active when the brain is at rest. Those with ADHD can achieve hyperfocus on things that are exciting to them, despite struggles with maintaining focus in general.

Brain imaging studies show that the default mode networks and task networks in individuals with ADHD are abnormally correlated, while in those without ADHD they interact in a seesaw fashion.

Summary
Brain imaging studies show that the default mode networks and task networks in individuals with ADHD are abnormally correlated, while in those without ADHD they interact in a seesaw fashion. When ADHD is treated, the networks tend to become anti-correlated again.

Dopamine acts as a conductor between the different brain networks, allowing them to stay out of phase or anti-correlated.

Summary
Dopamine acts as a conductor between the different brain networks, allowing them to stay out of phase or anti-correlated. In ADHD, the dopamine system is not conducting the networks properly, which raises questions of whether dopamine levels are not high enough or whether it is conducting them incorrectly.
