Closing in on seat of consciousness in the human brain

“the team investigated whether this brainstem-cortex network was functioning in another subset of patients with disorders of consciousness, including coma. Using a special type of MRI scan, the scientists found that their newly identified “consciousness network” was disrupted in patients with impaired consciousness. The findings – bolstered by data from rodent studies – suggest the network between the brainstem and these two cortical regions plays a role maintaining human consciousness.”

Part of the reason is just historical. As a weak metaphor, that fancy new computerized furnace / refrigerated air system you just installed at home is not going to work at all without the electrical system… Read more »
