Scientists Push Plan To Change How Researchers Define Alzheimer's
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.

When A High School Football Player Meets A Brain Injury Researcher
High School athletes often raise money door-to-door for their teams. In Newton, Mass., a football player rang the doorbell of a leading brain injury researcher. Instead of money, he got a talk.
Sorry, Adults, No New Neurons For Your Aging Brains
The brains of birds and mice continue to produce new nerve cells in the hippocampus throughout life. But research now suggests the human brain stops doing this around adolescence.
Still Thirsty? It's Up To Your Brain, Not Your Body
Thirst is what compels us to start hydrating. Now scientists have found a brain circuit in mice that seems to switch off thirst when they've taken in enough fluid and before it gets dangerous.
Your Besotted Brain: A Neuroscience Love Song
A Valentine's music video from Skunk Bear explores the ways your brain and body change when you fall in love — and change again as love deepens and matures.
A Tiny Pulse Of Electricity Can Help The Brain Form Lasting Memories
Technology that uses electrical stimulation to tweak the brain may eventually help people with memory problems caused by a brain injury or Alzheimer's disease.
Eating Leafy Greens Each Day Tied to Sharper Memory, Slower Decline
Scientists are keen to figure out how diet influences aging, including brain health. A 5-year study of healthy seniors found those who ate a serving or two of daily greens had less cognitive decline.
Why Your Brain Has Trouble Bailing Out Of A Bad Plan
Researchers say it takes a lot of brainpower to stop an action, once it's underway. A study found that when people have to change a planned movement, 11 different brain areas have to get involved.
Science And The Mystery Of The Mind
We are still as ignorant about the "passage from the physics of the brain to the corresponding facts of consciousness" as John Tyndall and his Victorian colleagues were, says Marcelo Gleiser.
Human Brains Have Evolved Unique 'Feel-Good' Circuits
A comparison of brain tissue from monkeys, chimps and humans suggests that our brains produce the chemical messenger dopamine, which plays a major role in pleasure and rewards, far differently.
