3D map of human brain is the most detailed ever - health - 20 June 2013
The folds, creases and intricate internal structures that make up the human brain are being revealed in unprecedented detail. A new three-dimensional map called BigBrain is the most detailed ever constructed, and should lead to a more accurate picture of how the brain's different regions function and interact. Until now, the precise placement of the neurons that make up our brain circuitry has been difficult to map, largely because the human brain's surface is covered with folds and creases. Slicing a brain exposes only two dimensions, so it is often unclear where and how the cells within these folds are organised in three-dimensional space. To make the new map, Katrin Amunts of the Jülich Research Centre in Germany and her colleagues embedded a 65-year old woman's brain in wax, sliced it into more than 7400 sections each 20 micrometres thick – one-fifth of the width of a human hair – and made digital images of the slices, also at a resolution of 20 micrometres.

Banishing consciousness: the mystery of anaesthesia - health - 29 November 2011
Read full article Continue reading page |1|2|3 I WALK into the operating theatre feeling vulnerable in a draughty gown and surgical stockings. I smile weakly and ask for a gin and tonic. I have had two operations under general anaesthetic this year. What they didn't tell me was how the drugs would send me into the realms of oblivion. The development of general anaesthesia has transformed surgery from a horrific ordeal into a gentle slumber. That is starting to change, however, with the development of new techniques for imaging the brain or recording its electrical activity during anaesthesia. Consciousness has long been one of the great mysteries of life, the universe and everything. Altered consciousness doesn't only happen under a general anaesthetic of course - it occurs whenever we drop off to sleep, or if we are unlucky enough to be whacked on the head. It was a Japanese surgeon who performed the first known surgery under anaesthetic, in 1804, using a mixture of potent herbs.
Does the head remain briefly conscious after decapitation (revisited)?
A Straight Dope Classic from Cecil's Storehouse of Human Knowledge June 12, 1998 Dear Cecil: In the answer about the guillotine in your online archive, you say that "the fatal blow induces immediate unconsciousness." — Joel Brusk, via AOL Dear Joel: Let's see. A lot of people disputed my claim that victims of the guillotine blacked out immediately. Not likely. But let's return to the original question, appalling though it may be: Is a severed head aware of its fate? It doesn't get any better. Is it possible? Then I received a note from a U.S. My friend's head came to rest face up, and (from my angle) upside-down. I've spoken with the author and am satisfied the event occurred as described. — Cecil Adams
Is 'Numerosity' Humans' Sixth Sense?
Whether it's determining the number of ships on the horizon or the number of cookies in a jar, the human brain has a "map" for perceiving numbers, new research shows. Topographical maps of the human brain are known to exist for the primary senses, such as sight, hearing and touch, but this is the first time such a map has been found for numerosity, or number sense. The map's layout allows for the most efficient communication among neurons doing similar tasks. Studies in monkeys have shown that certain neurons in the parietal cortex, located at the back of the brain beneath the crown of the hair, became active when the animals viewed a specific number of items. These studies did not find a map for numerosity, though scientists have long suspected one exists. [The Top 10 Mysteries of the Mind] "Scientists have suspected an ordered mapping of numbers for a long time," said Andreas Nieder, a neurobiologist at the University of Tübingen in Germany, who was not involved in the study.
Electronic health record
Sample view of an electronic health record An electronic health record (EHR), or electronic medical record (EMR), refers to the systematized collection of patient and population electronically-stored health information in a digital format.[1] These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHR systems are designed to store data accurately and to capture the state of a patient across time. Terminology[edit] The terms EHR, electronic patient record (EPR) and EMR have often been used interchangeably, although differences between the models are now being defined. In contrast, a personal health record (PHR) is an electronic application for recording personal medical data that the individual patient controls and may make available to health providers.[5] Comparison with paper-based records[edit] In ambulances[edit] Technical features[edit] Quality[edit]
Most Connected Hospitals 2012-13
The 156 hospitals listed below have met three challenging standards that put them in the vanguard of centers leading medicine into the era of electronic medical records (EMRs). Each is distinguished by having captured a national ranking in 2012-13 U.S. News Best Hospitals and/or Best Children’s Hospitals or by having earned the designation of “high-performing” in one or more medical specialties. And each hospital, or one or more of its major units--such as a children’s hospital within the larger institution--is a leader in moving to electronic medical records. The determination of which hospitals are leaders in EMR use was based on two criteria: By July 10, a hospital had to have met U.S. HIMSS Analytics scores hospitals’ EMR adoption on a scale from Stage 0 (none) to Stage 7 (full use across the hospital).
