"The shaman and physician for millennia were the same person until the 19th century when they were split apart in the name of science. Now through the lens of 21st-century science, Villoldo and Perlmutter bring them back together, illuminating the web that links together our physical and metaphysical energy. For anyone feeling a loss of energy of body or soul, Power Up Your Brain is your guide to restoration and rejuvenation of your deepest energies."
-- Mark Hyman, M.D., New York Times best-selling author of The UltraMind Solution

"This is the book we've been waiting for! With leading-edge information that's easy to understand, Alberto Villoldo and David Perlmutter have masterfully woven 21st-century science with the indigenous wisdom of the past to reveal the 'missing link' in the modern story of life--the role of our brain's health in the quality of our spiritual experience. In doing so they offer us a practical wisdom that we can use to empower our lives immediately! This book is a must for anyone seriously interested in moving beyond the conventional ideas of what enlightenment is and how to achieve it."
-- Gregg Braden, New York Times best-selling author of The Divine Matrix and Fractal Time

"This book is a treasure. It is a guidebook to enlightenment filled with the wisdom and experience of the authors. It relates the practical aspects of science to the spiritual and mystical realities of the nature of life. It clarifies what our potential is as human beings and directs us in the steps we need to take to achieve our potential and utilize the healing energy available to us all."
-- Bernie S. Siegel, M.D., author of Love, Medicine & Miracles and 365 Prescriptions for the Soul

"I seldom use the word 'brilliant, ' but this book is. It expands our awareness of the untapped potential of our brain, offers cutting-edge neuroscience, and is written by two experts with decades of hands-on clinical practice. See for yourself why Dr. Perlmutter is my personal neurologist and mentor."
-- Naomi Judd, singer, songwriter, and author of Naomi's Guide to Aging Gratefully

"This is one of the most important books I've ever read. Combining modern scientific knowledge and shamanic practices, it lucidly explains how to restore the health of the brain at the cellular level."-- David R. Hamilton, Ph.D., author of How Your Mind Can Heal Your Body
