- Middle English, from Old English brægen. (American Heritage® Dictionary of the English Language, Fourth Edition)
“As to the divisions of the greater brain or cerebrum, we want you to note that the _lower brain_ serves a double purpose.”
“Instantly the tiny nerve bulbs in the skin of the sole of your foot are stimulated, or set in vibration, and they send these vibrations up the sciatic nerve, into and up the whole length of the spinal cord, through the medulla, which switches them over to the other side of the brain up through the _brain stalk_, and out to the part of the surface (cortex) of the brain which controls the movements of the foot.”
“I think I can answer this question in a satisfactory manner, difficult though it seems; but in order that I may do so, I would ask the reader to lend me his attention for a few moments while we regard the brain simply _as brain_, and have no other idea concerning it than we can derive from inspection and reflection.”
“Having right timing 'connections' in brain is key to overcoming dyslexia”
“And honestly, I don't believe the general public is able to accept the truth of their own book because they have been so brain-trashed (I don't use the term brain-washed, because that means cleansed) with myths and lies as though they were truths.”
“David Kessler, author of the recent The End of Overeating, would say that my brain is a tool of the food industry, which rewires people to crave ever more of the sugar, salt, and fat it pumps into everything.”

“Its exam time at university and my brain is a little fried.”
“The other most important thing for survival besides your brain is your instincts and then all you need is a knife, a gun is more of a luxury and really a big help.”
“It seems that since the brain is anticipating a vibration from calls and text messages, it interprets the slightest friction as a phone vibration.”
