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.

Researchers have demonstrated the use of AI-selected natural images and AI-generated synthetic images as neuroscientific tools for probing the visual processing areas of the brain. The goal is to apply a data-driven approach to understand how vision is organized while potentially removing biases that may arise when looking at responses to a more limited set of researcher-selected images.

A first-line therapy for obsessive-compulsive disorder (OCD) reshapes connectivity of the brain, according to a new study

A new analysis of the brain activity of people with post-traumatic stress disorder (PTSD) is the first to reveal that traumatic memories are represented in the brain in an entirely different way than sad autobiographical memories.

Researchers have identified objective evidence of how the neck muscles are involved in primary headaches.

Optimal windows exist for action and perception during the 0.8 seconds of a heartbeat, according to research published in the open-access journal PLOS Biology. The sequence of contraction and relaxation is linked to changes in the motor system and its ability to respond to stimulation, and this could have implications for treatments for depression and stroke that excite nerve cells.

In a new study, researchers say they found high levels of a repair protein present long after a traumatic brain injury such as a concussion takes place.

A new study shows that individuals who report tinnitus, which presents as a ringing in the ears in more than 1 out of 10 adults worldwide, are experiencing auditory nerve loss that is not picked up by conventional hearing tests.

An international study group has identified how three novel genes cause neurodevelopmental disorders.

A new study has demonstrated that a novel treatment is effective in most patients with major depressive symptoms even after multiple failed courses of antidepressant medication. The treatment, repetitive transcranial magnetic stimulation (rTMS), may work even more rapidly than past findings have suggested, starting to alleviate symptoms as quickly as one week.

Finally this week, newborn babies can perceive the beat in music, new research has confirmed.
