consciousness meter.

this is awesome if we could measure the degree of consciousness like temperature...
they try to measure it based on the information amount in the subject's brain.
if lots of information flows, the brain is very conscious, otherwise, not so much.
i guess this idea or approach is closely related to Dr. Olaf Sporns' research,
which is to make a map of the brain network based on information flow.

anyway, recently, i see a lot of application of information theory to brain science
or even psychology...

maybe i am on the right track... ^^
