Brain augmentation refers to the different approaches which are aimed at improving the performance of the brain. These can be aimed at people who suffer from neurological problems as well as healthy people. The three major areas which can be augmented are classified as cognitive, motor and sensory domains. The performance of the brain can also be supplemented through brain-machine interfaces (BMI). These refer to the pathways that join neuronal circuits external assistive devices. A few of such devices are communication aids, exoskeletons and prosthesis of the limbs. Brain-machine interfaces are also useful for establishing communication in both directions, wherein artificial signals are sent to the brain while information from neural recordings is being decoded. The topics included in this book on brain augmentation are of utmost significance and bound to provide incredible insights to readers. It presents researches and studies performed by experts across the globe. Those with an interest in brain-machine interfaces would find this book helpful.
