Session Outline: The DMN and Autistic Inertia

1. "Hyper-connected" (The Eight-Lane Highway)

• Core Concept: The Default Mode Network (DMN) at rest.

• Neurotypical Brain: Wanders pleasantly (past, future, social). Analogy: Two-lane country roads.

• Autistic Brain: Specific hubs (special interests, patterns) are hyper-connected. Analogy: An eight-lane superhighway.

​

2. The "Sticky" DMN (The Gravity Well)

• Core Concept: Neurological "gravity" and looping.

• The Pull: The brain's attention naturally gravitates to the massive, fast "eight-lane highway" during rest.

• The Stickiness: Once there, the brain finds intense coherence or joy (or anxiety). It loops efficiently, lacking a natural reason to exit.

​

3. "Switching" as a Monumental Task (Autistic Inertia)

• Core Concept: The metabolic cost of transitioning.

• Neurotypical Transition: Easily diverts from the "country road" to the Task Positive Network (TPN) when an external demand occurs.

• Autistic Transition (Inertia): Requires immense metabolic energy to brake on a high-momentum loop, dismantle the connection, and reboot the external attention network.

​

4. Perseveration

• Core Concept: The behavioral outcome of the sticky DMN.

• Traditional View: Wrongly seen as a behavioral flaw or "stubbornness."

• Mechanical Reality: The brain is neurologically locked into a hyper-connected circuit and lacks the immediate metabolic torque to "pull the switch."
