The talk starts out with Chris demonstrating that you can 'mimic what
you see'. You can program the hundreds of muscle fibers in your hand
and arm, to duplicate someone else's wave.
He goes on to use this metapor as he talks of looking inside the brain,
and programming the brain areas directly.
fMRI for the masses uses a colleague, Peter, whose brain is zoomed
in on and dissected non-invasively via this technology, as a light introduction
to how brain activity state changes can be detected via fMRI.
"If you feel burnt, you pull your hand away, but if you still
feel pain in six months time, its because these circuits in your brain
are still producing pain that is no-longer helping you."
fMRI can watch these circuits in real-time (10ms delay), watch the
information processed and work out what is happening. By allowing the
patient to watch in real-time, they allow the patient to work on changing
their own brain patterns with interactive feedback.
