The book begins by laying a foundation in neuroscience, explaining how neural signals are generated and interpreted, then progresses to the different types of BCIs, from non-invasive EEG to implanted electrodes. It also examines signal processing algorithms and machine learning techniques essential for decoding neural signals, and hardware components of BCIs.
The book then explores the ethical and societal implications of BCIs, such as privacy, security, and autonomy, prompting consideration about consciousness, identity, and free will. The book aims to provide a balanced perspective on these brain technologies and the challenges that must be addressed to ensure their responsible development and deployment.
