Local calls only for anaesthetised brain

 Local calls only for anaesthetised brain

LAURA A team led by Lewis, Massachusetts Institute of Technology, and Patrick Purdon, Harvard Medical School, brain epilepsy was a window during the operation. Temporal cortex of each patient already, which means the team as they measure neuronal activity propofol, a general anesthetic was general had electrodes implanted in.The team asked each patient as they sound, the answer away. Then he stopped answering, Lewis and neuronal activity in cortical Purdon has seen dramatic changes. Slow-wave oscillations - brainwaves that deep sleep, the dream occur - has increased almost immediately.Anaesthetists have put people to sleep for years, but how they are using drugs, you send in your sleep is still largely a mystery. New research shows that long-distance communication in the brain involves obliteration.

Stop firing

Locally, the slow waves were synchronized neurons near each other in the waves where the peaks and troughs experienced in the coordination of activity, consistent communication means. However, slow waves across the cortex were not in sync.

Consciousness while at the same time in different areas of the cortex fire, if necessary, the neurons can communicate long distance. Each slow wave on top of a bridge in the brain represents the area was quiet - and the neurons stop firing. So a quiet area, in a region that is awake can not get a signal, synchronized slow waves of long distance communication near impossible.
Were about four square millimeters in harmony, in which neurons communicate before the patient lost consciousness.

Time zones

"These brain regions are in different time zones is like," said Lewis, the only other time zones represent the product. "The other is a field up."

Ludwig Lin, medical anesthetist at the University of California, San Francisco, medically speaking, anesthesia how much we know about brain functions, we believe that all patients for their actions you can not wake up with memories, that were not included in the study.

To achieve this goal, Lin's application form, including inhaled general anesthetics, drugs to see how a lack of awareness of the differences in the research hope to see, and that consciousness the loss of one's mind.
