Episode notes
Role of the Central Executive Network
- The Central Executive Network (CEN) activates in focused states, opposite the Default Mode Network (DMN).
- CEN manages executive functions like problem solving, working memory, and impulse control.
CEN Activation During Focus
- When fully engaged in a challenging or interesting task, your CEN is active, suppressing the DMN.
- This explains why you don't think much about the past or future during intense focus.
Functions Governed by the CEN
- Executive functions regulated by the CEN include planning, attention regulation, set shifting, and impulse control.
- Dysfunctions in these can lead to ADHD, binge eating, gambling, and substance use disorders.
