Sleep Deprivation Amps Up the Brain

Sleep deprivation making you feel jumpy? It's not in your head. Human cortical excitability increases with time awake. [Abstract and link to full paper.]

This is a subject of but small importance; and I know not whether it will interest any readers, but it has interested me.

"This is a subject of but small importance; and I know not whether it will interest any readers, but it has interested me."-C. D. Quick... what was Darwin's most popular book? If you answered The Origin of Species, you were wrong. It was his last book, published the year before he died, The Formation of Vegetable Mould Through the Action of Worms With Observation of Their Habits (illustrations [first presented 1 Nov. 1837, as noted in the record of the Royal Geological Society]). Darwin noted when he was beginning his career that worms churned up soil, causing heavier objects to sink slowly in the soil. He noted that all soil had passed through the alimentary duct of worms. It started off a fashion of cultivating worms by gardeners that continues to the present day. -We recently learned that we owe an element of our unique cerebral cortex, or pallium to our marine worm ancestors. (In amphibians, the cerebrum includes archipallium, paleopallium and some of the basal nuclei. Reptiles first developed a neopallium, which continued to develop in the brains of more recent species to become the neocortex of mammals." [&, ultimately, you and you and we]) [more inside]

Cool high-school science experiment: Mapping The Homunculus. The 15 year old in me wonders why nipples and other naughty bits aren't mentioned, though. Bet they'd be really big!!!
