20 Watts!! Is that on cruise mode or at its maximum capacity?
Brain Signal Persists Even in Dreamless Sleep 02.10.2008Neuroscientists at Washington University School of Medicine in St. Louis have taken one of the first direct looks at one of the human brain's most fundamental "foundations": a brain signal that never switches off and may support many cognitive functions..."The brain consumes a tremendous amount of the body's energy resourcesóit's only 2 percent of body weight, but it uses about 20 percent of the energy we take in," says Raichle. "When we started to ask where all those resources were being spent, we found that the goal-oriented tasks we had studied previously only accounted for a tiny portion of that energy budget. The rest appears to go into activities and processes that maintain a state of readiness in the brain."
I wonder how they measured it?
The brain makes up 2% of a person's weight. Despite this, even at rest, the brain consumes 20% of the body's energy. The brain consumes energy at 10 times the rate of the rest of the body per gram of tissue. The average power consumption of a typical adult is 100 Watts and the brain consumes 20% of this making the power of the brain 20 W.
I was just wondering if you could EVER stop thinking? When I try to do it I always notice myself holding my breath, maybe my brain stopped thinking for a second and turned many/every thing(s) off. You should try and stop thinking. Not that it probably helps burn many calories...
Me think its about impossible to stop thinking unless you are brain dead?
It's like staying awake in order to spot the instant when you drop off to sleep.

That's got me thinking.........OUCH! That hurts.If I stick a 20 watt bulb in my left ear, will it light up?
So I stick a Mars bar in my left ear and that will light up, right?
