Cerebral cortex Quotes

“I once read that if the folds in the cerebral cortex were smoothed out it would cover a card table. That seemed quite unbelievable but it did make me wonder just how big the cortex would be if you ironed it out. I thought it might just about cover a family-sized pizza: not bad, but no card-table. I was astonished to realize that nobody seems to know the answer. A quick search yielded the following estimates for the smoothed out dimensions of the cerebral cortex of the human brain.An article in Bioscience in November 1987 by Julie Ann Miller claimed the cortex was a "quarter-metre square." That is napkin-sized, about ten inches by ten inches. Scientific American magazine in September 1992 upped the ante considerably with an estimated of 1 1/2 square metres; thats a square of brain forty inches on each side, getting close to the card-table estimate. A psychologist at the University of Toronto figured it would cover the floor of his living room (I haven't seen his living room), but the prize winning estimate so far is from the British magazine New Scientist's poster of the brain published in 1993 which claimed that the cerebral cortex, if flattened out, would cover a tennis court. How can there be such disagreement? How can so many experts not know how big the cortex is? I don't know, but I'm on the hunt for an expert who will say the cortex, when fully spread out, will cover a football field. A Canadian football field.”

“It is an utter insult towards the fascinating neurons of your cerebral cortex, to believe anybody’s words blindly, even if that person is a Scientist or a Philosopher. So, I urge to you, that you must exercise your own reasoning and judgment (that’s what your cerebral cortex is for; to be specific the frontal lobes) at all times.”

“Civilization is a product of the cerebral cortex.”

“The cerebral cortex, the outer ‘skin’ of the brain, contains as many as ten billion neurons. This complexity is daunting. Yet it is out of complex interactions between the billions of neurons that consciousness arises.”

“Destiny is no more than the fulfillment of purposive potentialities within us. The human cerebral cortex is a single sheet composed of more neurons than there are stars in the known universe folded like a paper crane to fit in a quart-sized cubbyhole”

“There is no other species on Earth that does science. It is, so far, entirely a human invention, evolved by natural selection in the cerebral cortex for one simple reason: it works. It is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything.”

“We, through the cerebral cortex, add the consciousness, spirit and rationality, to this dolphin brained human body avatar. We control our destiny and this body can become a servant of our conscious will, once we learn to communicate fully with it. We are called to bridge the gap between our conscious mind and the subconscious mind.”

“We live in the Age of the Higher Brain, the cerebral cortex that has grown enormously over the last few millennia, overshadowing the ancient, instinctive lower brain. The cortex is often called the new brain, yet the old brain held sway in humans for millions of years, as it does today in most living things. The old brain can’t conjure up ideas or read. But it does possess the power to feel and, above all, to be. It was the old brain that caused our forebears to sense the closeness of a mysterious presence everywhere in Nature.”
