The misleading manifold?
The current debate (decoding vs causal relevance)
and a toy example I gave in the thread below
got me thinking about a related issue: how decoding may reflect structure more than function.

These, and other, studies show that you can decode task-related signals from many brain areas.
But wouldn't we need causal manipulations to conclude that the brain "uses" them?
For example, maybe we can decode equally well from two areas. But, only one impacts behaviour when inactivated.
