"Dietary Impact: How Your Food Choices Affect Brain Size"

A recent analysis of UK Biobank data suggests that individuals who frequently consume raw vegetables have a higher total volume of brain white matter, while those with a higher intake of fresh fruit generally have a lower total volume of grey matter but exhibit larger grey matter volumes in brain areas associated with dementia and depression. The study highlights the potential positive impact of regular consumption of fresh fruits and raw vegetables on brain structure, although the exact mechanisms behind these associations remain unclear.

Unveiling the Brain's Secrets through Pupil Dilation

New research suggests that pupil dilation during very light exercise could serve as a predictive marker for exercise-induced cognitive improvements. The study found that pupils dilated during exercise and the extent of dilation was associated with subsequent improvements in executive function performance. The researchers also observed increased activity in the prefrontal cortex during an executive function task after exercise. These findings highlight the role of the brain's arousal system in the cognitive benefits of exercise and suggest that pupil diameter changes could be a novel biomarker for understanding the effects of exercise on the brain.

Elsevier Journal Faces Mass Resignations Due to Unethical Price Hike

The editorial board of NeuroImage, a leading neuroscience journal published by Elsevier, has resigned over the publisher's decision to raise its open-access fees to $3,450. The editors have accused Elsevier of "pure greed" and have started a new non-profit journal, Imaging Neuroscience. The mass resignation highlights the high open-access charges levied by leading scientific journals, with Nature and Cell charging about £8,000. Elsevier has appointed an interim internal editorial team and said it values its editors highly.
