Researchers are using an advanced brain imaging method called MEG to understand why Parkinson’s drug levodopa doesn’t work equally well for everyone. By mapping patients’ brain signals before and ...

Most efforts to analyze connections involve scanning many brains and averaging the data across groups of people. For this study, the researchers used brain-imaging techniques to evaluate brain ...

A study suggests that a blood test measuring the biomarker pTau217 can detect early signs of Alzheimer’s disease years before ...

An experimental brain scan may be able to accurately predict a person’s risk of age-related disorders. Image credit: Rafe Swan/Getty Images. Some people appear to age more slowly than others. This is ...

White matter pathways allow distant parts of the brain to communicate, supporting memory, emotion, and language. One such ...

Peering into the human brain has never been easy. For decades, neuroscientists have relied on heavy, expensive machines to measure blood flow and oxygen levels that reveal how the brain works. These ...

A team of researchers in California has developed a way to use ultrasound imaging to provide a new view of brain activity — through a small window in the skull of one man. That window is not a ...

Luminescent protein, substrate, and oxygen all combine to create chemical chain reaction to produce light. Video shows the cortex of a mouse recorded over several minutes as the oxygen concentration ...

Some say you’re only as old as you feel. Others say you’re as young as you think. But how old is your brain really? Scientists have been developing and refining methods to accurately measure the age ...
