In 1989, a chance spreadsheet experiment led mechanical engineer Abraham Thomas to his revolutionary 'xCode' hypothesis. It challenges the prevailing scientific view that the brain's 86 billion neurons use algorithms to sum incoming signals. \Drawing from decades of neuroscience research and recent AI interactions, Thomas weaves a compelling 30-chapter narrative exploring the cellular, neurological and psychological foundations of human cognition. Discover how incoming combinatorial signal patterns are matched against a complex tapestry of genetic instructions, protein memories, subthreshold potentials, and neurochemical signatures. Explore this matching process that exposes the astronomically vast human memory. Glimpse Sigmund Freud's ambitious dreams and the curious philosophical revelations from an ordinary spreadsheet. Uncover amazing transplanted organ memories, the emotional gatekeeper role of the amygdala, and the brilliant bridge between determinism and free will. Unveil the insular cortex's link to self-awareness, how mirror neurons facilitate 90% of communication, and the somatic marker hypothesis' bar chart representation. Ponder consciousness' time lag, the 'thoughts organ', and the 'beliefs organ' sustaining knowledge. Through the 'XCode Mind' lens, Thomas offers a fresh perspective on humor, common sense, savant abilities, and even cosmic intelligence - with insights into mind control techniques and harnessing your own XCode Mind's power. "Taller Than a Tree" is a captivating journey into human cognition, challenging conventions and inspiring a new grasp of what it means to be human.
