Neuroscientist Dean Buonomano presents a revolutionary perspective on the relationship between the human brain and time, weaving together findings from evolutionary biology, physics and philosophy. His research reveals a fascinating truth: our brain is not a mere passive observer of time, but its active architect. Through rigorous exploration, Buonomano demonstrates how the human brain has evolved to become a sophisticated builder of temporal experiences. This capacity allows us not only to measure the passage of time, but also to project ourselves mentally and emotionally into the future or the past, an ability that proved crucial to the development of humanity. Without this capacity for temporal anticipation, fundamental advances such as the creation of tools or the development of agriculture would have been impossible. The book combines neuroscience with a multidisciplinary approach to address some of the most profound questions that have intrigued humanity: the nature of time, the mysteries of consciousness and the existence of free will. Buonomano examines how our understanding of space-time and relativity is intrinsically linked to the neural mechanisms that have evolved to help us navigate in an ever-changing universe. With a masterful balance between scientific rigor and accessibility, this work guides us through the intricate brain mechanisms that allow us to perceive, process and predict the flow of time. The result is a fascinating exploration that reveals how our brain has become a true time machine.
