Neuroscience

Open-source software reveals complete 3D architecture of brain cells

The neurons in our brain that underlie thought connect to each other using tiny branch-like structures on their surfaces known as dendritic spines. Now scientists at Columbia's Zuckerman Institute and their colleagues have ...

How the brain's activity, energy use and blood flow change as people fall asleep

A new study by investigators from Mass General Brigham has used next-generation imaging technology to discover that when the brain is falling asleep, it shows a coordinated shift in activity.

Scientists find ways to boost memory in aging brains

Memory loss may not simply be a symptom of getting older. New research from Virginia Tech shows that it's tied to specific molecular changes in the brain and that adjusting those processes can improve memory.

When we dream, does our brain wake up?

An international consortium of researchers has created the largest-ever database compiling records of brain activity during sleep and dream reports. One of the first analyses of the database confirmed that dreams do not occur ...

Radio waves amp up smell without surgery or chemicals

Our sense of smell is more important than we often realize. It helps us enjoy food, detect danger like smoke or gas leaks, and even affects our memory and emotions. Many people—especially after COVID-19, aging, or brain ...

3D-printed brain vessels replicate human blood flow patterns

Cerebrovascular diseases such as atherosclerosis and stroke remain a major cause of morbidity and mortality worldwide. A common feature of these diseases is vascular stenosis, i.e., the narrowing of blood vessels, which disrupts ...

New options are advancing rare brain cancer treatment

Art Sullivan, a 38-year-old Ironman athlete, and Josh Lehman, 48, who works at the University of Rochester, are connected by an unlikely foe: a type of brain tumor called an astrocytoma that tends to afflict younger adults. ...

Neuroscience

An alphabet for hand actions in the human brain

Using a corkscrew, writing a letter with a pen or unlocking a door by turning a key are actions that seem simple but actually require a complex orchestration of precise movements. So, how does the brain do it?

Neuroscience

Identifying a compass in the human brain

Zhengang Lu and Russell Epstein, from the University of Pennsylvania, led a study to explore how people maintain their sense of direction while navigating naturalistic, virtual reality cities.

Neuroscience

Early lead exposure could result in memory issues later in life

A new study has found that people who lived in areas with high levels of leaded gasoline emissions in the 1960s and '70s are more likely to report memory problems today—a finding that researchers say could deepen our understanding ...

Neuroscience

Scientists reveal how senses work together in the brain

It has long been understood that experiencing two senses simultaneously, like seeing and hearing, can lead to improved responses relative to those seen when only one sensory input is experienced by itself. For example, a ...
