Deans' stroke musings: Do neurons cross the central sulcus between the motor cortex and sensory cortex? Or do they connect through the white matter if necessary?

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Do neurons cross the central sulcus between the motor cortex and sensory cortex? Or do they connect through the white matter if necessary?

I had this question many years ago when I figured out that my sensory cortex seems intact but the motor and pre-motor cortex were badly damaged. I knew any doctor I talked to would not know the answer so I posted the question on Quora.

with a couple of great images.

The central sulcus is a valley in the outer folds of the brain's cerebral cortex. No axons cross the gap. But just below the central sulcus, the primary somatosensory cortex and the primary motor cortex are physically adjacent to each other, and are connected by short association fibres (SAF) from pyramidal neurons.
