Washington, Nov 12: Scientists suggest that neuroprosthetic brain implants may help stroke patients to overcome partial paralysis.

The researchers from Washington University School of Medicine in St. Louis discovered that implants known as brain-computer interfaces (BCI) may be able to detect activity on one side of the brain that is linked to hand and arm movements on the same side of the body.

For the first time, researchers at the University of Maryland School of Medicine in Baltimore have shown that the emotions aroused by joyful music have a healthy effect on blood vessel function.

Music, selected by study participants because it made them feel good and brought them a sense of joy, caused tissue in the inner lining of blood vessels to dilate (or expand) in order to increase blood flow, the study found.
