Physics Neuroscience

In Your Brain Is a Time Machine, brain researcher and best-selling author Dean Buonomano draws on evolutionary biology, physics, and philosophy to present his influential theory of how we tell and perceive time. The human brain, he argues, is a complex system that not only tells time but creates it; it constructs our sense of chronological flow and enables "mental time travel" - simulations of future and past events.

For the first time in history, the secrets of the living brain are being revealed by a battery of high-tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist.

In this groundbreaking book, world-renowned Buddhist teacher Yongey Mingyur Rinpoche invites us to join him in unlocking the secrets behind the practice of meditation. With an infectious joy and insatiable curiosity, he weaves together the principles of Tibetan Buddhism, neuroscience, and quantum physics in a way that will forever change the way we understand the human experience.

Throughout history, two perspectives on the world have dueled in our minds: the extrinsic—that of mechanism and physics—and the intrinsic—that of feelings, thoughts, and ideas. The intrinsic perspective allows us to tell stories about our lives, to chart our anger and our lust, to understand our psychologies. The extrinsic allows us to chart the physical world, to build upon it, and to travel across it. These perspectives have never been reconciled; they almost seem to exist on different planes of thought.

The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

From adrenaline to dopamine, most of us are familiar with the chemicals that control us. They are the hormones and neurotransmitters that our brains run on, and Overloaded looks at the role they play in every aspect of our lives, from what we remember, how we make decisions and who we love to basic survival drives such as hunger, fear and sleep.
