In this episode, we speak with Dr. Derek Buchanan about consciousness, brain function, and the clinical uses of neuroscience. We discuss how scientists define and study consciousness in states such as sleep, coma, and unresponsiveness, and how brain scans can reveal retained activity in some patients who appear unresponsive.
We also cover scientific and philosophical theories of consciousness, including ideas about awareness and information integration, and how different fields approach the same question. We then talk about research methods such as dreaming, anesthesia, psychedelics, brain-computer interfaces, and brain stimulation, as well as possible applications for conditions like depression, OCD, Parkinson’s disease, memory, and attention.
We discuss AI and its impact on consciousness. The episode ends with reflections on self-awareness, responsibility, emotional regulation, and the value of flexibility and apology in personal growth.
