neat, but why only focus on subvoxels? a non-smooth but very low-freq signal wd also show up with fMRI, no?

also, parsimony is a v. weak constraint here. even if some signal is smooth, plenty is probably non-smooth

if I understand correctly, you mean plenty in the brain is most definitely not smooth? Yes. I agree 1/2

that results show that some neural codes are implausible. they provide pos. evidence for _one_ scheme. 2/

and conclusion that “neural code must be smooth” at subvox isn’t true—it could be supravoxel non smooth

that said, was a great read. particularly like the point about abstract reps being (possibly) non-imageable

Amazing! This is super useful. Will check properly tomorrow as it's like after 10pm here.
