Neuroimaging – News and Features

In French Polynesia, scientists observed a previously undocumented, rapidly delivered but usually non-lethal type of shark bite in response to human aggression.

Researchers propose that mind blanking, characterized by a lack of mental content, is a distinct cognitive state. Unlike mind wandering, which involves active thought flow, mind blanking features reduced brain activity and physiological changes.

AI-assisted interpretation of brain scans may help improve care for children with brain tumors called gliomas, which are typically treatable but vary in risk of recurrence.

A new study has identified a potential new therapy for pulmonary tuberculosis that could shorten the length of treatment and prevent related lung conditions.

A study reveals unique brain activity during lucid dreaming. Using EEG data, the research identifies reduced beta-band power and increased gamma-band activity in specific brain regions.

Neurobiologists discovered that individual neurons can apply different plasticity rules in separate dendritic branches. This new understanding challenges prior assumptions of uniformity in synaptic changes and opens possibilities for improving AI.

Researchers found that when remembering multiple items, the brain prioritizes the more important ones by allocating more resources to them. They observed how the frontal cortex communicates with the visual cortex to adjust memory resolution.

A UT Southwestern study finds that higher cardiorespiratory fitness may slow age-related brain atrophy, preserving cognitive function. The study showed that those with better physical fitness had larger brain volumes and better cognitive performance.

Researchers at Massachusetts General Hospital developed a novel cannula delivery system for effective compound administration during multiphoton microscopy, allowing for extended in vivo brain imaging.

Researchers have developed a treatment for Parkinson’s disease that involves creating nerve cells from embryonic stem cells and transplanting them into patients. Early results show the treatment is safe and may improve Parkinson’s symptoms.
