Your brain activity can be used to measure how well you understand a concept

As students learn a new concept, measuring how well they grasp it has often depended on traditional paper and pencil tests. Researchers have developed a machine learning algorithm, which can be used to measure how well a student understands a concept b…

An 8-hour work week could be ideal for mental health

How many hours of paid work per week are actually beneficial for mental health? It could be as little as 8, suggests a new study from the United Kingdom.

Epilepsy and sudden death linked to bad gene

In sudden death in epilepsy, people stop breathing for no apparent reason and die. Now, a group of UConn neuroscientists have a lead as to why. Many neurologists argue that a bad seizure can travel through the brain to cause breathing or heartbeat malf…

Largest study of CTE finds it in 6% of subjects

Nearly 6% of athletes and non-athletes were found to have the neurodegenerative disorder chronic traumatic encephalopathy (CTE) in the largest, and broadest, study conducted of the disease to date. Kevin F. Bieniek, Ph.D., of UT Health San Antonio is t…

Squeezing of blood vessels may contribute to cognitive decline in Alzheimer’s

Reduced blood flow to the brain associated with early Alzheimer’s may be caused by the contraction of cells wrapped around blood vessels, according to a new study that opens up a new way to potentially treat the disease.

Pigs help scientists understand human brain

For the first time, researchers have used an imaging method normally reserved for humans to analyze brain activity in live agricultural swine models, and they have discovered that pig brains are even better platforms than previously thought for the stu…

Early-and-regular cannabis use by youth is associated with alteration in brain circuits that support cognitive control

The development of neural circuits in youth, at a particularly important time in their lives, can be heavily influenced by external factors — specifically the frequent and regular use of cannabis. A new study reports that alterations in cognitive cont…

Recognizing the hidden signs of depression

People with depression can experience a variety of symptoms, some of which may be harder to recognize than others. Hidden symptoms of depression can range from fatigue and changes in sleeping patterns to anger and losing interest in pleasurable activit…

How information is like snacks, money, and drugs — to your brain

A new study has found that information acts on the brain’s dopamine-producing reward system in the same way as money or food. The study is the first to demonstrate a common neural code for information and money.

First-ever successful mind-controlled robotic arm without brain implants

Researchers have made a breakthrough in the field of noninvasive robotic device control. Using a noninvasive brain-computer interface (BCI), researchers have developed the first-ever successful mind-controlled robotic arm exhibiting the ability to cont…
