Exposure to high ambient temperatures is associated with lower connectivity in three brain networks in preadolescents, suggesting that heat may impact brain function. 

A new study reveals that consuming high-calorie, highly processed foods for just five days can reduce the brain’s sensitivity to insulin, a key factor in obesity and type 2 diabetes. Researchers found that even in healthy individuals, short-term unhealthy eating altered brain function, mimicking effects seen in people with obesity.

Scientists are exploring the role of gut-brain axis in Parkinson’s, anxiety and long COVID.

New research highlights that optimal brain health is strongly linked to cardiovascular wellness. The study underscores that dementia and cognitive decline share risk factors with heart disease, suggesting these conditions are largely preventable by managing diet, exercise, cholesterol, blood sugar, and blood pressure.

Approximately 40 percent of adults with chronic pain experience depression or anxiety, according to a review published in JAMA Network Open.

A multidisciplinary team of researchers has discovered how lateral inhibition helps our brains process visual information, and it could expand our knowledge of sensory perception, leading to applications in neuro-medicine and artificial intelligence.

Brain changes may remain visible in brain scans after recovery from concussion, a new study shows.

Researchers are using photoacoustic imaging to observe brain activity and, in the process, discovering more about how it responds to different types of learning and experiences. Photoacoustic imaging uses optics and acoustics to generate a signal in biological tissues—in this case, the brain—where the signal provides structural and functional data and allows researchers to track factors such as brain activity. 

A study exploring a new brain imaging technique is bringing stroke experts a step closer to better tailoring rehabilitation.

Scientists have uncovered new insights into how neurofilaments act like Velcro in neurodegenerative diseases, clogging up the brain and preventing normal function, according to a study published in the journal JCI Insight.

Poor sleep could have an impact on brain health, according to a new study from The Australian National University (ANU) published in the journal Sleep Medicine.

Mayo Clinic researchers have found a new way to more precisely detect and monitor brain cell activity during deep brain stimulation, a common treatment for movement disorders such as Parkinson’s disease and tremor. This precision may help doctors adjust electrode placement and stimulation in real time, providing better, more personalized care for patients receiving the surgical procedure.

A new neuroimaging study has revealed that viewing nature can help ease how people experience pain, by reducing the brain activity linked to pain perception.

An international team of scientists has revealed new clues about the neural mechanisms underlying memory formation and recognition in the developing human brain, according to a study published in Science Advances.

Poor sleep among older adults is linked to disruptions in the brain’s “waste removal system,” according to a recent study.

Research published in the Proceedings of the National Academy of Sciences  reveals that brain aging isn’t a steady decline, but rather a series of shifts with key turning points. These transition points follow an S-shaped statistical curve with clear transition points, rather than either the late-life clinical onset or gradual linear decline previously assumed, suggesting there are specific windows when intervention could be most impactful.

Finally this week, new research reveals that our brains simplify complex social interactions by using basic mental “building blocks” or shortcuts.
