Research Sheds New Light on the Brain
According to a recent study published in the New England Journal of Medicine, general anesthesia does not truly place a patient’s brain in a state of “sleep” as it is commonly termed. During the study the brains of subject were observed in both states of natural sleep as well as under general anesthesia. The results were surprising to some.
The brain activity of someone under anesthesia, it turns out, actually resembles the activity of a patient in a coma. Coma patients are in a deep state of unconsciousness where it is believed no dream activity takes place. This is in stark contrast to a person actually sleeping. As a person sleeps they actually cycle through several states of consciousness, including REM sleep, during which the brain is very active in some areas as people dream.
The study is part of an effort to better understand sleep and sleep disorders as well as medical aid for coma patients.
