The Body in Depth

April 22, 2008

The classic 25-volume “Stereoscopic Atlas of Human Anatomy” will soon be made available online by Stanford University’s school of medicine and eHuman, a company in Silicon Valley.

Eventually, it will be possible to see the images online in stereo.

The book beyond the book

December 28, 2011

Bartleby the Scrivener

Melville House has introduced a new series, HybridBooks, to meld the e-reading and traditional book cultures, New York Times Bits reports.

The Hybrids are “enhanced print books” with nothing inside but a short classic text. The last page directs readers to a Web site, where they will find, for example, an 1852 map of lower Manhattan, a recipe, excepts from Emerson and Thoreau, and similar material.

The bootless PC and terabytes on a dime

September 20, 2006

Imagine a PC with instantaneous boot up or storing 10TB of data on a device the size of a dime with data-transfer rates unhampered by any latency.

The Boss Is Robotic, and Rolling Up Behind You

September 7, 2010

(InTouch Health)

Mobile robots are now being used in hundreds of hospitals nationwide as the eyes, ears and voices of doctors who cannot be there in person.

They are being rolled out in workplaces, allowing employees in disparate locales to communicate more easily and letting managers supervise employees from afar. And they are being tested as caregivers in assisted-living centers.

The brain can process images seen for just 13 milliseconds

MIT neuroscientists have found that the human brain can process entire images that the eye sees for as little as 13 milliseconds — the first evidence of such rapid processing speed.

That speed is far faster than the 100 milliseconds suggested by previous studies. In the new study, which appears in the journal Attention, Perception, and Psychophysics, researchers asked subjects to look for a particular type of… read more

The Brain in Winter

January 2, 2002

Although some neural functioning is lost from aging, the biggest recent surprise in neuroscience is the discovery of neurogenesis: as the brain ages it creates new neurons.

The BRAIN Initiative: BAM or BUST?

What is the BRAIN* Project about? What are its goals?

“Well, nobody knows, actually. I certainly don’t know. But it appears that no one else knows either.” So says Scicurious, a PhD in Physiology and currently a postdoc in biomedical research, on her The Scicurious Brain blog on Scientific American.

“Basically, BRAIN is a very fancy initiative, with a fancy name … and so far,… read more

The brain is wired in a 3D grid structure, landmark study finds

March 30, 2012


The brain appears to be wired in a rectangular 3D grid structure, suggests a new brain imaging study funded by the National Institutes of Health.

“Far from being just a tangle of wires, the brain’s white-matter connections turn out to be more like ribbon cables — folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a… read more

The brain may be able to repair itself from within, Duke researchers discover

Duke researchers have found a new type of neuron in the adult brain that is capable of telling stem cells to make more new neurons.

Neuroscientists have suspected for some time that the brain has some capacity to direct the manufacturing of new neurons, but it was difficult to determine where these instructions are coming from, explains Chay Kuo, M.D. Ph.D., an assistant professor of… read more

The Brain May Use Only 20 Percent of Its Memory-Forming Neurons

April 20, 2007

Researchers at the University of California, Los Angeles and The Hospital for Sick Children have found that the pace at which a brain cell activates a key protein, CREB (a transcription factor that typically increases the production of other proteins in cells) may influence its role in memory formation — a finding that could lead to new Alzheimer therapies

The brain organizes objects by size: MIT scientists

June 22, 2012


Researchers at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) and Department of Brain and Cognitive Sciences have discovered that the brain organizes objects based on their physical size.

A specific region of the brain is reserved for recognizing large objects and another is reserved for small objects.

Their findings could lead to a greater understanding of how the brain organizes and maps information,… read more

The brain scan that can read people’s intentions

February 11, 2007

A team of world-leading neuroscientists has developed a powerful technique that allows them to look deep inside a person’s brain and read their intentions before they act.

The team used high-resolution computed tomography (CT) brain scans to identify patterns of activity before translating them into meaningful thoughts, revealing what a person planned to do in the near future. They revealed signatures of activity in the medial prefrontal cortex that… read more

The Brain Starts to Change at Age 40

June 11, 2004

Researchers at Children’s Hospital in Boston and Harvard Medical School report that aging brains show significant differences in the behavior of several groups of genes that are important for brain function and that may contribute to the aging process.

One group of the genes plays a role in “synaptic plasticity” — the ability of the brain to make new connections so critical to learning and memory. Another group of… read more

The Brain That Changed Everything

October 26, 2010


In 1953, the majority of the hippocampus of Henry Molaison (the man who could not remember) along with some surrounding neuronal tissue, was surgically removed from both hemispheres of his brain. Because of Molaison, it is known that memory function originates in this region.

When Jacopo Annese finishes constructing his multidimensional, zoomable atlas of H.M.’s brain, scientists will be able to see at the neuronal level exactly how… read more

The Brain Under Anesthesia

April 3, 2008

A large-scale study published in the New England Journal of Medicine has found that a commonly used device designed to prevent anesthesia awareness–the rare event when a patient is actually conscious during surgery–was largely ineffective.

Massachusetts General Hospital researchers are using brain imaging of human volunteers and, in animals, electrophysiology approaches–which more directly measure brain activity–to gain a deeper understanding of anesthesia. Their preliminary research suggests that measuring activity… read more
