Lasting impact of concussions on young adults

Researchers have found that young adults who experienced repetitive mild traumatic brain injury (mTBI), or concussions, can experience persistent cognitive changes as well as altered brain activity.

MRI technique shows unique signatures of concussion in rugby players

The research team studied the brains of young female athletes and used a technique that combined multiple brain imaging measures to be able to look at structural and functional information at the same time. The result was a much more sensitive and comp…

Nutrients in blood linked to better brain connectivity, cognition in older adults

A new study links higher levels of several key nutrients in the blood with more efficient brain connectivity and performance on cognitive tests in older adults.

Peering into Little Foot’s 3.67-million-year-old brain

MicroCT scans of the Australopithecus fossil known as Little Foot shows that the brain of this ancient human relative was small and shows features that are similar to our own brain and others that are closer to our ancestor shared with living chimpanze…

How do anxiety and depression affect physical health?

New research investigates the physical health risks associated with anxiety and depression and compares them with those of smoking and obesity.

Two-step control mechanism identified in mouse stem cells

Scientists identified two distinct control mechanisms in the developmental transition of undifferentiated stem cells into healthy brain cells. This fundamental research using mice may inform regenerative medicine treatments for neurodegenerative diseas…

Simply receiving DNA test results can alter your physiology

A fascinating new study demonstrates that simply being told we have a genetic risk can alter the way our body behaves, even if the risk does not exist.

Depression, anxiety may take same toll on health as smoking and obesity

An annual physical typically involves a weight check and questions about unhealthy habits like smoking, but a new study suggests health care providers may be overlooking a critical question: Are you depressed or anxious?

Gently stroking babies before medical procedures may reduce pain processing

Researchers found that gently stroking a baby seems to reduce activity in the infant brain associated with painful experiences. Their results suggest that lightly brushing an infant at a certain speed — of approximately 3 centimeters per second — cou…

Communication between neural networks

Researchers are proposing a new model to explain how neural networks in different brain areas communicate with each other.
