New evidence puts into doubt the long-held depression belief

New evidence puts into doubt the long-standing belief that a deficiency in serotonin - a chemical messenger in the brain - plays a central role in depression. In the journal ACS Chemical Neuroscience, scientists report that mice lacking the ability to make serotonin in their brains (and thus should have been "depressed" by conventional wisdom) did not show depression-like symptoms.

Brain's motor cortex can directly turn down hearing

When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. This strategy helps us hear better by preventing unwanted sounds generated by our own movements.

Study provides neural explanation for why some skills are easier to learn than others

Learning is easier when it only requires nerve cells to rearrange existing patterns of activity than when the nerve cells have to generate new patterns, a study of monkeys has found. The scientists explored the brain's capacity to learn through recordings of electrical activity of brain cell networks.

Engineers bring touch of color to glucose monitoring

University of Illinois engineers are bringing a touch of color to glucose monitoring. The researchers developed a new continuous glucose monitoring material that changes color as glucose levels fluctuate, and the wavelength shift is so precise that doctors and patients may be able to use it for automatic insulin dosing - something not possible using current point measurements like test strips.
