It is widely recognised that our physical fitness is reflected in our mental fitness, especially as we get older. How does being physically fit affect our aging brains? Neuroimaging studies, in which the activity of different parts of the brain can be visualised, have provided some clues. Until now, however, no study has directly linked… Read more

Beginning in infancy, people who have autism spectrum disorder observe and interpret images and social cues differently than others do. Researchers now have new insight into just how this occurs, which eventually may help doctors diagnose, and more effectively treat, the various forms of the disorder. Symptoms of autism spectrum disorder (ASD) include impaired social… Read more

Alzheimer’s patients frequently suffer from sleep disorders, mostly even before they become forgetful. Furthermore, it is known that sleep plays a very important role in memory formation. Researchers from the Technical University of Munich (TUM) have now been able to show for the first time how the pathological changes in the brain act on the… Read more

Researchers at NYU Langone Medical Center say they have added to evidence that a shell-shaped region in the center of the mammalian brain, known as the thalamic reticular nucleus or TRN, is likely responsible for the ability to routinely and seamlessly multitask. The process, they suggest, is done by individual TRN neurons that act like… Read more

Memories of the same events co-exist at different resolutions in the brain, neuroscientists from Radboud University’s Donders Institute have shown. Coarse and fine memory scales are distributed across different parts of the hippocampus, a brain area that plays an important part in memory. Our memories exist in different resolutions. For example, last Friday you might… Read more
