What happens when the brain can still form an intention, but the body can no longer carry it out?For people living with severe paralysis, the ability to communicate, move, or interact with the world can be profoundly affected. Yet advances in neuroscience and biomedical engineering are opening an extraordinary new possibility: using neural signals to create alternative pathways between the brain, computers, robotic systems, and the human body.The Brain-Computer Revolution explores the rapidly developing field of brain-computer interfaces (BCIs) and the technologies being investigated to restore communication and movement after neurological injury and disease.From the electrical activity of individual neurons to artificial intelligence capable of decoding complex neural patterns, this book explains how researchers are transforming signals from the brain into commands that can operate computers, robotic limbs, communication systems, and other assistive technologies.Inside, readers will discover how: Brain-computer interfaces detect and interpret neural activityResearchers decode movement intentions from the brainNeural signals can support communication when speech is impairedExperimental speech neuroprostheses are converting brain activity into text and synthesized speechBrain-controlled robotic arms and prosthetic systems are being developedFunctional electrical stimulation and brain-spinal interfaces may help reconnect the nervous system with the bodyArtificial intelligence is improving neural signal decoding and adaptive controlSensory feedback could make future neuroprostheses more natural to useResearchers are moving BCI technology from laboratory demonstrations toward clinical applicationsNeural implants raise important questions about privacy, autonomy, safety, cybersecurity, and informed consentThe next generation of neurotechnology could create increasingly sophisticated connections between biology and machinesRather than treating brain-computer interfaces as science fiction or promising a cure for paralysis, this book examines what the technology has actually demonstrated, where researchers are making progress, and where significant challenges remain.It explores the science behind neural recording, signal processing, machine learning, neuroprosthetics, brain-controlled communication, robotic movement, rehabilitation, and emerging brain-spinal technologies in language that readers without an advanced neuroscience background can understand.The Brain-Computer Revolution offers an informative look at one of the most important intersections of modern neuroscience, medicine, artificial intelligence, and engineering-and considers what it could mean for the future of people living with paralysis and other neurological disabilities.
