This image shows the buildup of toxic tau proteins in the medial temporal gyrus of a human brain. Though some drugs can now remove these proteins, that hasn't seemed to ease Alzheimer's symptoms. It's time to look more deeply into how the cells work, sci

Alzheimer's Researchers Go Back To Basics To Find The Best Way Forward

Jun 25, 2020
After a decade of failure in treating Alzheimer's with drugs, the National Institutes of Health is funding a five-year effort in Seattle to learn more about how the disease starts in the brain.

Scientists say pea-size organoids of human brain tissue may offer a way to study the biological beginnings of a wide range of brain conditions, including autism, bipolar disorder and schizophrenia.

After Months In A Dish, Lab-Grown Minibrains Start Making 'Brain Waves'

Aug 29, 2019
Researchers say clusters of human brain cells grown in the lab can spontaneously generate electrical patterns similar to the brain waves of a 6-month-old fetus.

Researchers studying mouse brains identified the cells that encode pain's unpleasantness.

Scientists Find Brain Cells That Make Pain Hurt

Jan 17, 2019
Researchers have pinpointed the neurons that give pain its unpleasant edge. By turning these neurons off in mice, the scientists relieved the unpleasantness of pain without numbing sensation.

UCLA researchers are using a radioactive tracer, which binds to abnormal proteins in the brain, to see if it is possible to diagnose chronic traumatic encephalopathy in living patients. Warmer colors in these PET scans indicate higher concentrations of t

Scientists Hunt For A Test To Diagnose Chronic Brain Injury In Living People

Jul 17, 2018
Doctors are closer to a test in live brains that could help diagnose chronic traumatic encephalopathy, a disease that's been linked to concussions and other repeated brain assaults.

Scientists placed two clusters of cultured forebrain cells side by side (each cluster the size of a head of a pin). Within days, the "minibrains" had fused and particular neurons (in green) migrated from the left side to the right side, as subsets of cel

'Minibrains' In A Dish Shed A Little Light On Autism And Epilepsy

Apr 26, 2017
Experiments with small clusters of networked brain cells are helping scientists see how real brains develop normally, and what goes awry when cells have trouble making connections.

This image is from lab-grown brain tissue — a minibrain — infected by Zika virus (white) with neural stem cells in red and neuronal nuclei in green.

'Minibrains' Could Help Drug Discovery For Zika And For Alzheimer's

Nov 13, 2016
Each lab-grown cluster of human cells fits on a pin's head, but contains some of the cell types and circuitry of a real brain. The structures already are offering insights into how Zika attacks.

A relaxed, undrugged dog patiently waits its turn in the MRI scanner. The scientists' trick: Make it seem fun.

How A Dog In An MRI Scanner Is Like Your Grandma At A Disco

Sep 08, 2016
To study dogs' brain activity, scientists had to train canines to hold absolutely still for eight minutes without restraint. But how do you get a dog to freeze that long inside a clanging MRI scanner?

A Protein That Moves From Muscle To Brain May Tie Exercise To Memory

Jun 23, 2016
In mice, monkeys and people, exercise releases a protein called cathepsin B. And as blood and brain levels of this protein rise, memory gets better. But the protein has a dark side, too.
