MEN’S BRAINS SHRINK AT NIGHT

A new study from the University of California, Santa Barbara, published in The Journal of Neuroscience, says that men’s brains shrink at night. Researchers scanned a 26-year-old’s brain 40 times over 30 days. They found that his overall brain volume decreased throughout the day, as did the thickness of the cortex, the brain’s outermost layer. It has to do with hormones. Researchers say this cycle of growing and shrinking coincides with rising and falling levels of the hormones testosterone, cortisol and estradiol. There can be a 70 per cent decrease from morning to night in steroid hormones. Less hormones means a smaller brain. The study says women’s hormones also fluctuate daily but it’s not as pronounced as in men. The researchers point out that they only did the research on one person, so it can’t necessarily be applied to a wider population.
* Aw, jeeze, couldn’t you at least have done two — the other guy, and yourself while you’re at it? Would that have been so hard?
* And scanning somebody’s brain 40 times in 30 days can’t be good.
* Sure, our brains shrink at night but, come on… it’s colder at night.
* This explains why I can’t do differential calculus when I’m dreaming. I mean, I can’t do it during the day either, but I’m just sayin’.
* I’m guessing the researchers thought up this study in the middle of the night when their brains were the tiniest.
