Researchers have developed a suite of free tools for analyzing vast amounts of brain dissection photographs at brain banks worldwide to enhance understanding of neurodegenerative diseases.

A new study reveals a strong link between regular physical activity and enhanced brain health. Analyzing MRI scans from 10,125 individuals, researchers found that exercise, even moderate exercise like walking, is associated with increased brain volumes in crucial areas like gray matter, white matter, and the hippocampus. The study underscores exercise’s role in reducing dementia risk and maintaining brain size.

Scientists have discovered that a part of the brain associated with working memory and multisensory integration may also play an important role in how the brain processes social cues.

In a first-of-its-kind study published in Nature, researchers recorded activity from hundreds of individual neurons while participants listened to spoken sentences, giving us an unprecedented view into how the brain analyzes the sounds in words.

A new study has unveiled three distinct cognitive deficits contributing to reading difficulties in individuals with left-sided neglect dyslexia, a condition that often follows a right-hemisphere stroke.

Researchers have unveiled a significant similarity between AI memory processing and human hippocampal functions. This discovery, bridging AI and neuroscience, highlights a parallel in memory consolidation – a process crucial in transforming short-term to long-term memories – in both AI models and the human brain.

A new study highlights the significant role of imagination in evoking empathy and driving prosocial behaviour. 

A so-called pathological protein long associated with Parkinson’s disease has been found in a new study to trigger cells to increase protein synthesis, an event that eventually kills the subset of brain cells that die off in this neurodegenerative condition.

A new study presents a promising treatment for restoring the sense of smell in long-COVID patients.

Researchers have found that amyloid oligomers play a role in speeding up mitochondrial energetics during the early stages of Alzheimer’s, in contrast to what has been previously found in more advanced Alzheimer’s brain tissues. The results are published in Nature Communications.

Research led by the Karolinska Institutet, Sweden, has found an increased risk of cardiovascular disease associated with long-term ADHD medication use.

New research has uncovered a potential early marker for autism in infants: abnormally enlarged perivascular spaces (PVS) in the brain. The study found that infants with enlarged PVS had a 2.2 times greater chance of developing autism compared to those with the same genetic risk. The researchers followed infants with a higher likelihood of autism due to having an older sibling with the condition.

A pilot clinical trial has found electrical stimulation of the spinal cord is feasible, well-tolerated and shows therapeutic potential to treat depression.

Signs of injury to the brain’s white matter called white matter hyperintensities, as seen on brain scans, may be tied more strongly to vascular risk factors, brain shrinkage, and other markers of dementia in former tackle football players than in those who did not play football, according to a study published in Neurology.

Artificial intelligence, coupled with data from an iPad coloring game, could assist in early diagnosis of autism, a new study shows.

A review in the Journal of Internal Medicine explores the potential of non-invasive interventions such as light, sound, and magnets to stimulate gamma brain waves for the treatment of Alzheimer’s disease. Such strategies may be beneficial because Alzheimer’s disease is characterized by reduced fast brain oscillations in the gamma range (30–100 Hz).

Finally this week, researchers have made a significant breakthrough in understanding the genetic basis of anxiety disorders (ADs), which affect over 280 million people globally.
