Drugs of abuse: Identifying the addiction circuit

What happens in the brain of a compulsive drug user? Neurobiologists have discovered that the brain circuit connecting the decision-making region to the reward system is stronger in compulsive animals. The researchers also found that by decreasing the …

How the brain reacts to loss of vision

If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organization of the cerebral cortex and on memory. Researchers demonstrated that, in the months after blindness emerged, the density …

Computer hardware designed for 3D games could hold the key to replicating human brain

Researchers have created the fastest and most energy efficient simulation of part of a rat brain using off-the-shelf computer hardware.

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.
