Consciousness Detection Techniques

The video discusses consciousness research, focusing on disorders like coma and vegetative state. It explains the use of fMRI to detect consciousness in patients who appear unresponsive. The method involves asking patients to imagine activities, which show distinct brain patterns. The video also covers the potential applications and challenges of this research, including its use in medical decisions.
