Energy brain consumption

The human brain consume around 20% of the body total energy when it’s in a resting state. The brain functions are to process and to transmit information. It transmit it’s information by using electrical signals.

How does the brain energy consumption is measure?

FMRI – Functional magnetic resonance imaging is a magnetic tool use to monitor the blood flow which in turn allow us to detect activity in the brain.

It’s like a MRI – Magnetic resonance imaging. This machine can create a 3D image of the inside of the human body.
