Art depends on our brains. By understanding what goes on in our brains...we can hope to deepen our appreciation of both the art and science." David Hubel, neuroscientist, Nobel Laureate Drawing: The Art-Science Connection; Pens, Pencils, and Neurons. With the advent of Cognitive Neuroscience, the divide between art and science is narrowing as the two domains explore their common interests - the human brain. Recent developments in imaging technology is making correlations that heretofore were not possible, providing us with answers as to the "what, why, and how" we do things - including the making of art. Hence the theme, purpose, and intent of this book, supplemented with over 300 informative illustrations.
