The human brain is a part of the human nervous system. This organ is responsible for controlling almost all the activities of the body. The augmentation of the brain refers to the different ways in which the performance of the brain can be boosted. It can also be used to repair the brain of a person who suffers from a neurological disease. This can be done through a variety of methods such as through brain implants, brain-machine interfaces (BMI), or through pharmacological or electrical stimulation. There are also non-invasive techniques which can activate specific areas of the brain. This book unfolds the innovative aspects of brain augmentation which will be crucial for the progress of this field in the future. The recent studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
