Enum: MeasureType¶

Normalized scientific quantity of the map, for cross-study queries. Activation and deactivation are directions rather than measure types; both are bold_response and the directional roles carry the direction. Gray-matter density is not collapsed into volume. A paper that does not identify the measure leaves the slot extraction_status: not_reported. Open vocabulary: write the source's own wording in the field when nothing here fits.
