Neurobiologist Quotes

The neurobiologist Harry Jerison has made a long study of the trajectory of brain evolution since the advent of life on dry land. ...the origin of new faunal groups is usually accompanied by a jump in the relative size of the brain, known as encephalization. ...the first archaic mammals... were equipped with brains four to five times bigger than the average reptilian brain... primates are twice as encephalized as the average mammal. Within primates, the apes... are some twice the average size. And humans are three times as encephalized as the average ape. (Richard Leakey)
From the point of view of the modern neurobiologist, the question whether the mind exists as an autonomous being or is simply a derivative of the coordinated action of the brain cells is unscientific and irrelevant. Regardless of the possibility of an independent existence of the soul, it has no chance to express itself without a functioning brain. View quote
