The brain is the most complex organ, that serves as the center of the nervous system.
The brain is a network. It consists of spatially distributed, but functionally linked regions that continuously share information with each other. Interestingly, recent advances in the acquisition and analysis of functional neuroimaging data have catalyzed the exploration of functional connectivity in the human brain.
The particular anatomy of the brain, which is enclosed and protected by a rigid skull, creates a unique pressure-volume relationship compared to the rest of the human body, as already described by Alexander Monro and Kelly.
