This chapter unfolds the remarkable journey of neurotechnology—a field at the confluence of neuroscience and engineering, transforming our interaction with machines and profoundly enhancing human capabilities. Through captivating accounts of individuals overcoming neurological conditions with cutting-edge devices, we dive into the heart of neurotechnology’s promise and its realization. From brain implants enabling communication for those paralyzed by amyotrophic lateral sclerosis, to robotic arms granting independence to individuals with tetraplegia, and the empowerment of those with spinal cord injuries to walk again, these narratives are not mere stories but milestones in neurotechnology’s evolution from fantasy to reality. In this chapter, we explore the historical context of tools and techniques that have facilitated the reading, modulation, and augmentation of brain activity. As we journey through neurotechnology’s past and present and envisage its future, this chapter serves as a starting point to explore the tools, techniques, and applications encompassing the field of neurotechnology throughout the two volumes of this book series.
