Numerosity receptive fields
— participant sub-12
Each vertex is colored by its preferred numerosity (μ,
5–25), its tuning width (σ, log space, 0.1–2.0),
both estimated per stimulus-range condition, or by the
cross-validated variance explained of the encoding model
(cvR² > 0 shown). The white contour marks NPCr
(right numerosity parietal cortex). Maps for model 31 (the
paper's winning model, fixed 1.29 width scaling) and model 14
(tuning width free per voxel) only cover NPCr, the region they were
fitted in. Keys:i/f inflate or flatten the
surface (here “flat” means fully inflated, no cut-open
flatmap), +/− step through the maps.
Each dot is one NPCr voxel with cvR² > 0: its preferred
numerosity (μ) or tuning width (σ) in the narrow (x) vs the
wide (y) range condition. Dashed line: no change between conditions.
Values are the actual voxel fits (not surface-resampled).
Selecting a model or parameter here also switches the brain map
(and +/− updates this panel).
