I've just read Buzan's Head First, and I have become increasingly interested in the brain. I like to visualise the photoread book hitting the visual cortex at the back of the head, then moving in ripples through the 'thinking cap' of the cerebral cortex and the hippocampus.

Does the ability to visualise the brain processes involved in PR increase their efficacy? Has anyone done MRI scans on Photoreaders photoreading to see which parts exactly of the brain are made active. I would be most interested to find out.
