Quick answers

Where should I start with fMRI?

Read Overview → Anatomy → Function, then use compare rails.

Is this page advice for fMRI?

Educational atlas — not a diagnosis, treatment plan, or medical advice.

What does the local lens add?

It names everyday desks for Methods before English norms look universal.

Are the scores a ranking of fMRI?

No — editorial 0–100 browsing aids inside this atlas only.

How do I compare fMRI to neighbours?

Use related cards and best-of / quiz rails after the first three chapters.

Which chapter is densest?

Anatomy and Function carry mechanisms; skim Overview first.

Start with this section - Function

Function pages turn anatomy into computations — what fMRI actually does.

Processes and networks below summarise mainstream models, not a single dogma.
