Metamaterial might improve TMS depression treatment

November 5, 2013

TMS headpiece

A brain stimulation technique that is used to treat tough cases of depression could be considerably improved with a new headpiece designed by University of Michigan engineers.

Computer simulations showed that the headpiece — a square array of 64 circular metallic coils — could one day help researchers and doctors hit finer targets in the brain that are twice as deep as they can reach… read more

MIT chemists have built a sensor using carbon nanotubes that can monitor nitric oxide (NO) in living animals for more than a year.

Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed.

“Nitric oxide has contradictory roles in cancer progression, and we need new… read more

Light stimulates brain activity during a cognitive task even in some people who are totally blind, according to a study conducted by researchers at the University of Montreal and Boston’s Brigham and Women’s Hospital.

“We were stunned to discover  that the brain still responds to light in these rare three completely blind patients  despite having absolutely no conscious vision at all,” said senior co-author Steven… read more

Neurocam wearable camera reads your brainwaves and records what interests you

November 1, 2013

neurocam

The neurocam is the world’s first wearable camera system that automatically records what interests you, based on brainwaves, DigInfo TV reports.

It consists of a headset with a brain-wave sensor and uses the iPhone’s camera to record a 5-second GIF animation. It could also be useful for life-logging.

The algorithm for quantifying brain waves was co-developed by Associate Professor Mitsukura at Keio University.

Gliese436b

MIT researchers have found that Kepler 78b, a small, intensely hot planet 400 light-years from Earth discovered by the researchers in August, shares Earth’s mass.

By analyzing the movement of its host star, Kepler 78, the scientists determined that the exoplanet is about 1.7 times as massive as the Earth.

From the same measurements, they calculated that the planet’s density is 5.3 grams… read more
