Tailored for both consumers and NeuroTech developers/researchers, this evidence book offers a comprehensive exploration of the scientific foundation of NeuroTech based on systematic reviews. It highlights the importance of caution when approaching these technologies, due to the current lack of evidence supporting many of the claims. Compared to the original version 1.2, this updated edition includes answers to five additional questions related to neurofeedback, non-invasive brain stimulation, and EEG psychophysical markers. The book aims to provide accurate information to the public, enhance transparency, and help consumers make informed decisions about the use of NeuroTech products.

This evidence book was developed as part of the "Liberation from Biological Limitations via Physical, Cognitive and Perceptual Augmentation (Project Manager Ryota Kanai)" project for Goal 1 of the Cabinet Office Moonshot Research and Development Program, "Overcoming limitations of body, brain, space, and time" by 2050. The funders, the Japan Science and Technology Agency, and the Cabinet Office, had no involvement in the development or content of this book.
