Do I understand this correctly?
The hierarchy of the regions of neocortex is increasingly invariant (as to the sensory patterns recognized) the higher up the hierarchy you go. But as I understand it, lower level regions do not coordinate their motor output perfectly therefore what gets sent from the lower regions is basic movements.
For example, if the goal is to pick up a pencil the lower regions effectively just say, “move arm” which is a far cry from the fine motor control required to actually pick up a pencil. But is it true that the higher regions, modulate this by sending finer refinements in their own motor commands?
If so, does that mean that the higher up the hierarchy you go the more the cortex is consumed by modeling potential behaviors rather than recognizing patterns? Does that mean that the higher up the hierarchy you go the more you model self, and self’s interaction with the environment as separate things? Does that mean it’s almost an inverse hierarchy as far as invariance go (that further up the hierarchy, the more variant, the more motor commands you’re sending out)?
