Scientists Develop Computer Model Explaining How Brain Learns to Categorize

March 16, 2015 10:37 am | by NYU | News | Comments

New York University researchers have devised a computer model to explain how a neural circuit learns to classify sensory stimuli into discrete categories, such as “car vs. motorcycle.” Their findings, which appear in the journal Nature Communication, shed new light on the brain processes underpinning judgments we make on a daily basis.

Does Amyloid Kill in Alzheimer’s, Heal in MS?

March 13, 2015 10:30 am | by Cynthia Fox, Science Writer | Articles | Comments

Two groups have recently made strides with amyloid beta (aβ), the supposed main villain in Alzheimer’s disease. But while one group is tackling Alzheimer’s by reducing aβ, the other is tackling multiple sclerosis (MS) by using aβ.

Magnetic Brain Stimulation

March 13, 2015 9:30 am | by David L. Chandler, MIT | News | Comments

Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles — a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
