Researchers map how measles virus spreads in human brain

Mayo Clinic researchers used genetic sequencing to study the measles virus's spread in a human brain. The study found that the virus acquired distinct mutations that drove its spread from the frontal cortex outward. This knowledge may help develop effective antiviral drugs to combat SSPE, a rare and lethal brain disease caused by measles.

Slimming significantly alters your microbiome and brain activity

A study of 25 obese Chinese individuals reveals that intermittent energy restriction (IER) alters the gut microbiome and brain activity, leading to significant weight loss and reductions in obesity-related comorbidities. The changes are coupled over time, suggesting a complex relationship between the gut microbiome and brain.

New gene therapy could significantly reduce seizures in severe childhood epilepsy

Researchers at UCL Queen Square Institute of Neurology have developed a new gene therapy that significantly reduces seizures in mice with focal cortical dysplasia. The treatment, which involves the overexpression of a potassium channel, has shown an average reduction of 87% in seizures without affecting the mouse's memory or behavior.

AI screens for autism in the blink of an eye

Researchers have developed an AI-powered system to diagnose autism spectrum disorder (ASD) in children using a single flash of light to the eye. The system uses electroretinography (ERG) to identify specific features that classify ASD, providing a faster and more accurate method for diagnosis than existing tests.

Smoking causes brain shrinkage

A recent study published in Biological Psychiatry: Global Open Science found that smoking causes brain shrinkage and increases the risk of age-related cognitive decline and Alzheimer's disease. Quitting smoking can prevent further loss of brain tissue, but stopping does not restore the brain to its original size.

Fermentation may have driven human brain evolution

A new hypothesis suggests that fermentation of cached food provided a more accessible form of nourishment, fueling the growth of larger brains in human ancestors. This idea is supported by the fact that the human large intestine is proportionally smaller than other primates and fermented foods are found across cultures.

Repeated blast exposures may harm the brain health of military personnel

A study found increased brain inflammation and structural changes in special operations personnel exposed to blasts, potentially increasing the risk of long-term brain-related disease. The research suggests that repetitive exposure to low-level blasts may cause brain injuries and highlights the need for better protective measures.

Traumatic memories are represented differently than regular sad memories in the brains of people with PTSD, new research shows

A new study found that traumatic memories in people with PTSD are represented in the brain in a distinct way, deviating from regular memory processing. The hippocampus and posterior cingulate cortex regions showed different neural responses to traumatic and sad autobiographical memories.

Brain waves usually found in sleep can protect against epileptic activity

Researchers at University College London have discovered that slow waves typically present during sleep can also occur during wakefulness in people with epilepsy, potentially protecting against increased brain excitability. These 'wake' slow waves decrease the impact of epileptic spikes on brain activity and may protect against seizures.
