“The tape measures and weighing scales of the Victorian brain scientists have been supplanted by powerful neuroimaging technologies, but there is still a lesson to be learned from historical examples such as these. State-of-the-art brain scanners offer us unprecedented information about the structure and working of the brain. But don't forget that, once, wrapping a tape measure around the head was considered modern and sophisticated, and it's important not to fall into the same old traps. As we'll see in later chapters, although certain popular commentators make it seem effortlessly easy, the sheer complexity of the brain makes interpreting and understanding the meaning of any sex differences we find in the brain a very difficult task. But the first, and perhaps surprising, issue in sex differences research is that of knowing which differences are real and which, like the intially promising cephalic index, are flukes or spurious.”

“No one's brain is different enough to make constant interruptions, distractions, and task-switching an optimal environment in which to function. No one's.”

“Our metaphors for the operation of the brain are frequently drawn from the production line. We think of the brain as a glorified sausage machine, taking in information from the senses, processing it and regurgitating it in a different form, as thoughts or actions. The digital computer reinforces this idea because it is quite explicitly a machine that does to information what a sausage machine does to pork. Indeed, the brain was the original inspiration and metaphor for the development of the digital computer, and early computers were often described as 'giant brains'. Unfortunately, neuroscientists have sometimes turned this analogy on its head, and based their models of brain function on the workings of the digital computer (for example by assuming that memory is separate and distinct from processing, as it is in a computer). This makes the whole metaphor dangerously self-reinforcing.”

“There is a distinct difference between having an open mind and having a hole in your head from which your brain leaks out.”

“An important verity about knowledge is that the brain works most effectively with consciously retained information. We more easily remember what we want to recall later. When we feed our fourteen billion brain cells with information that will enrich us and help others, we are really learning to Think Big.”

“- My instructors in science and technology have taught us about how the brain works. It's full of electrical impulses. It's like a computer. If you stimulate one part of the brain with an electrode, it...- They know nothing.”
