Brain-Computer Interface - Mysteries of the Brain

The video explores the concept of brain-computer interfaces (BCI), a technology that allows the brain to communicate with computers. Dr. Rajesh Rao, a neural engineer, is developing non-invasive BCI devices to control prosthetics and computers. The video explains how neurons control body functions and how researchers use this knowledge to control machines. A demonstration using an EEG cap shows how BCIs can interpret brain signals for nonverbal communication. Advanced techniques like electrocorticography provide clearer signals for imagined movements. The future of BCI involves seamless integration of brain and technology, enhancing adaptability and control.

Explain the process of how a student uses an EEG cap to answer questions.
