the claim

fMRI scans measure neural activity directly.

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 6 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that fMRI scans measure neural activity directly?

No. Multiple reference and peer-reviewed sources describe fMRI as estimating neural activity indirectly, by measuring blood flow or blood-oxygenation (BOLD) changes rather than neural activity itself. One source explicitly calls the direct-measurement reading technically incorrect.
