Little known Facts about the human brain

"Relax, this won't hurt a bit..."

There are no pain receptors in the brain. That's why surgeons can perform brain surgery on a patient why they are still awake. This helps them ensure that the delicate procedure doesn't screw up any vision or motor control functions – and also it looks really freaky. Why do we feel pain? Because a nociceptor, a sensory receptor, sends signals to the spinal cord and brain alerting us to danger. Couldn't they just send a card? (Source 1 | Source 2 | Photo)

100, 000 Miles of Blood Vessels in the Brain

There are also a hundred billion neurons that comprise the brain – as many as in the entire galaxy – all in a squishy mass about the size of a cantaloupe. Using about 17% of your body's energy and 20% of its oxygen, while only containing 2% of its mass, the brain produces between 10-23 watts of power when awake - enough to light a bulb. Made of 75% water, your noodle has over 100 trillion synapses that connect those neurons and enough “space” to hold the entire Enclyclopedia Britannica fivefold, or 1, 000 terrabytes of information. And the Cheech and Chong myth isn't true; you do use your entire brain, even when high. (Source 1 | Source 2)

They Saved Einstein's Brain

When Albert Einstein died in 1955, they didn't just save a lock of his crazy white hair, they carved out his whole melon. Dr. Thomas Harvey performed the brainectomy a mere seven-and-a-half hours after Einstein's death, purportedly for scientific research. Then it vanished. It wasn't until 1978 that an intrepid journalist named Steven Levy tracked down Dr. Harvey in Wichita, Kansas, where the good doctor admitted he still had the brain, sliced in 240 pieces and bobbing in two mason jars filled with formaldehyde.

The Brain Feels No PainThere Are Differences Between the Right and Left Brain

The brain is split up into two symmetrical hemispheres. While they do work together, the left brain favors more rational, analytical thinking, while the right is more visually and conceptually oriented. They also work in opposites – you stub your left toe and the “pain” is processed on the right side. And they put right-side-up whatever is upside-down – the image in your eyes is actually received inverted and the brain corrects it. But here's the REALLY weird thing – even if you were to lose one-half of your brain, you would be able to survive without it. Well, maybe that's not so weird – look at all those stupid politicians!

Sorry Ladies, Men's Brains are 10% Bigger

So there you go – concrete proof that men are smarter than women. But before you go patting yourselves on the back, dudes, note that although women's brains are smaller, they have more nerve cells and connectors and work more efficiently than men's. And, true to the stereotype, they tend to process on the more “emotional” right side of the brain, while men process on the “logical” left. Also, an area known as the straight gyrus, responsible for nurturing, feminine traits, is proportionately larger in women. Does this mean there ARE indeed brain-related differences between the sexes? You WOULD think that, wouldn't you?! Typical… (Source 1 | Source 2)
