'If the human brain were so simple that we could understand it, we would be so simple that we couldn't,' wrote George M. Pugh, quoting his father in his book 'The Biological Origin of Human Values'. Ever since its discovery, the brain has been speculated about. Scientific papers that discuss the properties of the brain date back to an Egyptian doctor 3000 BC.
＂If the human brain were so simple that we could understand it, we would be so simple that we couldn＇t,＂ wrote George M. Pugh, quoting his father in his book ＂The Biological Origin of Human Values＂. Ever since its discovery, the brain has been speculated about. Scientific papers that discuss the properties of the brain date back to an Egyptian doctor 3000 BC. Aristotle thought that the brain＇s primary use was cooling the blood after the heart did all of the thinking in the body, though Hippocrates was much more appreciative. One of the biggest barriers to understanding the brain is the huge number of constantly shifting pathways within it, containing around one hundred billion neurons, each having thousands of connections to others. The Brain is mainly composed of two components： Grey Matter and White Matter.
