Exercise can maintain or even increase the size of certain brain regions, which may help ward off cognitive decline.

Improving blood flow to the brain through regular exercise enhances cognitive function and reduces inflammation, which is linked to cognitive decline.

The design of our brains allows us to prioritize attention efficiently, which is crucial for navigating our environments and making decisions.

Recent advancements have allowed scientists to map the brain's connectome, which is a significant step in understanding brain function and could lead to breakthroughs in treating neurological issues.

Engaging in difficult tasks can help maintain brain circuitry, allowing for greater cognitive vigor as we age.

Even low levels of alcohol consumption can lead to thinning of the neocortex, indicating potential brain degeneration.

Low to moderate alcohol consumption may still negatively impact brain health, potentially causing neurodegeneration.

Both light and moderate alcohol consumption can reduce brain thickness, indicating negative effects on brain health, and there's a dose-dependent increase in the shrinkage of gray matter and white matter tracts in the brain as a function of alcohol consumption.

Even mild dehydration can diminish cognitive and physical performance, so it's important to maintain adequate hydration and electrolyte levels for brain health.
