Imagined movements can alter our brains

Brain-computer interfaces (BCI) work on the principle that measurable changes in electrical brain activity occur just by thinking about performing a task. Signals can be read, evaluated, and then converted into control signals ...

New technique may reveal the health of human hair follicles

A variety of factors can stop hair from forming and growing properly, leading to hair diseases and baldness. A new method developed by investigators at Massachusetts General Hospital (MGH) recently examines the activity of ...

New method visualizes groups of neurons as they compute

Using a fluorescent probe that lights up when brain cells are electrically active, MIT and Boston University researchers have shown that they can image the activity of many neurons at once, in the brains of mice.

How can ultrasonic brain stimulation cure brain diseases?

Just as rays of sunlight can be focused by a magnifying glass, beams of ultrasound can be focused—not to start a fire, but to converge on a specific target. The pulses of ultrasound are able to pass through obstructions ...

 A model for brain activity during brain stimulation therapy

Brain stimulation, where targeted electrical impulses are directly applied to a patient's brain, is already an effective therapy for depression, epilepsy, Parkinson's and other neurological disorders, but many more applications ...
