EEG Helps Researchers Understand Sedation And Consciousness

Brett Smith for redOrbit.com — Your Universe Online Doctors and surgeons have been using general anesthetic to induce unconsciousness for over one hundred years, but little work has been done to define what unconsciousness actually is. A new study in the Proceedings of the National Academy of Sciences from a group of Massachusetts General Hospital (MGH) researchers has defined consciousness more thoroughly by using a high quality electroencephalogram (EEG) to identify the brain...

Lawrence LeBlond for redOrbit.com - Your Universe Online Fainting is a fairly common occurrence in our society and about 25 percent of us will experience it at some point in our life. And now, a new study has found that there is a strong link between fainting and family. Studying identical and fraternal twins, researchers from Australia and the US suggest people who are predisposed to fainting get it through genetics. Described as a sudden, brief loss of consciousness after blood...

Why does inhaling anesthetics cause unconsciousness? New insights into this century-and-a-half-old question may spring from research performed at the National Institute of Standards and Technology (NIST). Scientists from NIST and the National Institutes of Health have found hints that anesthesia may affect the organization of fat molecules, or lipids, in a cell's outer membrane–potentially altering the ability to send signals along nerve cell membranes. "A better fundamental...

For the first time researchers have been able to watch what happens to the brain as it loses consciousness. Using sophisticated imaging equipment they have constructed a 3-D movie of the brain as it changes while an anesthetic drug takes effect. Brian Pollard, Professor of Anesthesia at The University of Manchester (UK), will tell the European Anesthesiology Congress in Amsterdam that the real-time 3-D images seemed to show that losing consciousness involves a change in electrical activity...

WEST ORANGE, N.J., Aug. 19 /PRNewswire/ -- With fall sports season beginning, millions of students are preparing to take to the field. Among those playing football, soccer or other contact sports, more than 3.8 million will sustain a brain injury*, with football-related injuries being the most prevalent. "Mild traumatic brain injury (MTBI), often called a concussion, is the most common sports-related head injury, but one of the most difficult to diagnose," explains Neil N. Jasey, M.D.,...

MADISON, Wis. -- The brains of people under anesthesia respond to stimuli as they do in the deepest part of sleep "“ lending credence to a developing theory of consciousness and suggesting a new method to assess loss of consciousness in conditions such as coma. Scientists at the University of Wisconsin School of Medicine and Public Health, led by brain researcher Fabio Ferrarelli, reported their findings in this week's edition of the Proceedings of the National Academy of Science. The...
