With less structure and supervision than is typically provided inside a classroom, remote classes lean hard on already stressed parents to help students with ADHD stay focused and engaged.
How The Brain Teases Apart A Song’s Words And Music
By: Jon Hamilton | NPR
Posted on:
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.
Researchers Link Autism To A System That Insulates Brain Wiring
By: Jon Hamilton | NPR
Posted on:
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.
Subtle Differences In Brain Cells Hint at Why Many Drugs Help Mice But Not People
By: Jon Hamilton | NPR
Posted on:
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.
A Genetic Test That Reveals Alzheimer’s Risk Can Be Cathartic Or Distressing
By: Jon Hamilton | NPR
Posted on:
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.
Decoded Brain Signals Could Give Voiceless People A Way To Talk
By: Jon Hamilton | NPR
Posted on:
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.
Ketamine May Relieve Depression By Repairing Damaged Brain Circuits
By: Jon Hamilton | NPR
Posted on:
Scientists are learning how the party drug ketamine relieves depression so quickly — and why its effects fade over time.
Scans Show Female Brains Remain Youthful As Male Brains Wind Down
By: Jon Hamilton | NPR
Posted on:
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.
Scientists Find A Brain Circuit That Could Explain Seasonal Depression
By: Jon Hamilton | NPR
Posted on:
Research suggests the winter blues are triggered by specialized light-sensing cells in the retina that communicate directly with brain areas involved in mood.
Researchers Uncover A Circuit For Sadness In The Human Brain
By: Jon Hamilton | NPR
Posted on:
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.
Active Ingredient In Marijuana Reduced Alzheimer’s-Like Effects In Mice
By: Jon Hamilton | NPR
Posted on:
In mice genetically programmed to develop Alzheimer’s symptoms, those given a synthetic version of a chemical in marijuana retained normal memory function.
The Underestimated Cerebellum Gains New Respect From Brain Scientists
By: Jon Hamilton | NPR
Posted on:
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.
Worried About Dementia? You Might Want to Check Your Blood Pressure
By: Jon Hamilton | NPR
Posted on:
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.
Scientists Push Plan To Change How Researchers Define Alzheimer’s
By: Jon Hamilton | NPR
Posted on:
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.
