The brain as a model for future supercomputers External Link

A Sandia National Laboratories-supported workshop in Albuquerque called NICE, for Neuro-Inspired Computational Elements workshop, discussed ways to use the brain’s superior ability to send electrical signals along massively parallel channels, with multiple intersections at downstream nodes, to handle rapidly changing, high-volume information.

The hope is that rather than using the limited “if this, then that” logic of conventional computer architectures to absorb steadily increasing yet often incomplete data, cognitive systems will be able—like the brain—to learn, adapt, hypothesize, and then suggest answers.

Man finds out his runny nose was actually a leaky brain External Link

A man who experienced a nearly constant runny nose was actually leaking brain fluid through his nostrils, according to Fox 10 News.

Joe Nagy of Arizona had suffered from a seemingly endless runny nose. Doctors figured it was just a bad case of allergies, but Nagy’s symptoms were unaffected by medications.

Cute, meet sad: First-ever brain surgery performed on a bear

In the mountains of northern Laos, a three-year-old Asiatic black bear has become a medical pioneer: the world’s first bear to undergo brain surgery.

The bear, named Champa, has lived most of her life at a sanctuary run by Free the Bears, an Australian nonprofit group. About 20 miles (32 kilometers) south of the city of Luang Prabang, the sanctuary protects bears that Lao officials have rescued from wildlife traffickers. The Asiatic black bear, or moon bear, whose bile is considered a valuable ingredient in traditional Chinese and Korean medicine, is listed as vulnerable on the IUCN Red List of Threatened Species.

Rescued as a cub, Champa stood out from the start: She had a protruding forehead and had trouble socializing with the other bears at the sanctuary. Over time, her growth slowed, her behavior became more erratic, and her vision faded.

Sanctuary staff and veterinarians suspected hydrocephalus, or “water on the brain,” a disease that strikes humans as well as animals. It’s most commonly caused by the blockage or overproduction of cerebrospinal fluid in the brain’s cavities.

In most Western countries, a wild animal with hydrocephalus would likely be euthanized. “Having hydrocephalus is like having an absolutely mind-blowing, constant migraine,” said veterinarian Romain Pizzi. But because of the strong Buddhist tradition in Laos and the technicalities of its wildlife protection laws, euthanasia was not an option.

So Free the Bears called on Pizzi, a South African veterinary surgeon who works in Scotland at the Edinburgh Zoo and also at a national wildlife rescue center. Pizzi uses a technique called “keyhole,” or laparoscopic surgery, in which surgery is performed through a small incision and with the help of a camera.

The amazing neuroscience of why music is actually rewarding to the brain

image

Listening to music is an “intellectual” reward, which results from interactions between subcortical dopaminergic regions involved in forming predictions that we share with other animals, and cortically stored templates of previously heard music that are unique to each individual, along with some of the most evolved parts of the cerebral cortex involved in complex pattern recognition and sequencing. These regions ultimately work together to assign reward value to an abstract stimulus.

A new study reveals what happens in our brain when we decide to purchase a piece of music when we hear it for the first time. The study, conducted at the Montreal Neurological Institute and Hospital – The Neuro, McGill University and published in the journal Science on April 12, pinpoints the specific brain activity that makes new music rewarding and predicts the decision to purchase music.
