Police officers face twice the risk of traumatic brain injuries and PTSD, survey finds

Police officers are more than twice as likely to have traumatic brain injuries compared to the general population.

The brain resorts to myelin when other brain nutrients are depleted

Marathon runners experience reversible changes in their brain myelin. These findings indicate that myelin (a substance that surrounds the neurons) exhibits behavior that was previously unknown, and that it contributes towards the brain’s energy metabol…

How mothers adapt to the metabolic demands of nursing

Nursing poses major metabolic demands on mothers, to which they respond by eating more and saving energy to sustain milk production. There are significant hormonal changes during lactation, but how they lead to metabolic adaptations in nursing mothers …

AI models of the brain could serve as ‘digital twins’ in research

In a new study, researchers created an AI model of the mouse visual cortex that predicts neuronal responses to visual images.

Eight or more drinks per week linked to signs of injury in the brain

Heavy drinkers who have eight or more alcoholic drinks per week have an increased risk of brain lesions called hyaline arteriolosclerosis, signs of brain injury that are associated with memory and thinking problems, according to a new study.

Father with Alzheimer’s? You may be more at risk of brain changes

While some studies have suggested that having a mother with Alzheimer’s disease may put you more at risk of developing the disease, a new study finds that having a father with the disease may be tied to a greater spread of the tau protein in the brain …

Scientists map unprecedented detail of connections and visual perception in the mouse brain

In a massive scientific effort, hundreds of researchers have helped to map the connections between hundreds of thousands of neurons in the mouse brain and then overlayed their firing patterns in response to visual stimuli. This breakthrough is a critic…

Novel drug delivery platform paves way to potential new treatments for Alzheimer’s, other brain-related disorders

Researchers have discovered a way to get anti-inflammatory medicine across the blood-brain barrier, opening the door to potential new therapies for a range of conditions, including Alzheimer’s disease, multiple sclerosis, Parkinson’s disease and cancer…

New insights into neurodegeneration using human ‘mini brains’

Researchers have discovered a new way that neurons act in neurodegeneration by using human neural organoids — also known as ‘mini-brain’ models — from patients with frontotemporal lobar degeneration (FTLD). Understanding this new pathway could help r…

long-term effects of obesity on brain and cognitive health

With the global prevalence of obesity on the rise, it is crucial to explore the neural mechanisms linked to obesity and its influence on brain and cognitive health. However, the impact of obesity on the brain is complex and multilevel.
