I'll look for the book mooh.

Tattie is right, while looking for a new hypothesis based on the data of a most active cerebellum processing orientation in space when the eyes are closed, could the cerebellum be the minds eye when the visual cortex is sending no input?

When in a symphonic orchestra visual input is essential for precise timing. Sound is actually too slow in a large area to rely upon when a total unification is required. When an antiphonal brass choir is added to a balcony only light is fast enough to achieve simultaneous sound for a certain segment of a music hall. The larger the group of musicians the more sight is important.

My question is - is the visual cortex the minds eye or does the cerebellum simply coordinate with 'imagined vision' when eyes are closed
