Coma Is Equal To Daydreaming?
To find out whether brain-damaged patients will regain consciousness, researchers conducted a study on brain-injured patients with a variety of different levels of consciousness. Some part of the brain can stay active even the brain is severely damaged, and this could help to understand the chances of recovery. The “default network” in the brain seems to match the level of consciousness, and it is more active when the brain is not actively working and that links with daydreaming. With the help of default network, there is a 10% fall in normal activity in in minimally conscious patients, while in coma and “persistent vegetative state” patients, it falls by 35%, and no activity in the brain-dead patients.
Researchers believe that activity within the network will help to confirm the level of consciousness, and help the medical team to decide whether or not to treat the patient.
