Brain scans show that when people listen to songs, an area in the left hemisphere decodes speech-like sounds while one on the right processes musical information.
Brains affected by autism appear to share a problem with cells that make myelin, the insulating coating surrounding nerve fibers that controls the speed at which the fibers convey electrical signals.
A detailed comparison of mouse and human brain tissue found differences that could help explain why mice aren’t always a good model for human diseases.
Genetic tests can now tell us a lot about our risk for developing Alzheimer’s disease. But that doesn’t mean people are prepared to receive the information.
Scientists have found a way to transform electrical signals in the brain into intelligible speech. The advance may help people paralyzed by a stroke or disease, but the technology is experimental.
Scientists are learning how the party drug ketamine relieves depression so quickly — and why its effects fade over time.
Researchers say the metabolism of a woman’s brain remains higher than a man’s throughout a lifetime. And that may help with late-life creativity and learning.
Research suggests the winter blues are triggered by specialized light-sensing cells in the retina that communicate directly with brain areas involved in mood.
When people are feeling glum, it often means that brain areas involved in emotion and memory are communicating. Researchers have now observed the circuit in action in humans.
In mice genetically programmed to develop Alzheimer’s symptoms, those given a synthetic version of a chemical in marijuana retained normal memory function.
A brain structure that helps us walk in a straight line also appears to play a central role in emotional control and decision-making. The findings about the cerebellum challenge years of dogma.
A new public health campaign says controlling high blood pressure is among the best ways to keep your brain sharp. The neurologist in charge aims to lead by example.
Research scientists say they want to define Alzheimer’s by the biological changes it causes in the brain, rather than by symptoms like memory loss.
