The video, The Secret You, looks at the topic of the difference in consciousness between waking and sleeping. Marcus de Sautoy undergoes an experiment that measures the consciousness in our brain when we are awake and asleep. The experiment involves a cap of electrodes that is onto his head and a trans cranial magnetic stimulation (TMS) that discharges electrical shocks. From this, we can measure how the electrical shocks spread and the difference of when we lose consciousness.The data recorded while we are awake showed different areas away from the stimulated side being active and are described as an interacting network. But, while we are asleep the stimulation remains local and ultimately the communication networks in the brain shut down. The researcher's results were both reliable and repeatable. Therefore, our consciousness can be explained as parts of our brain integrating and communicating together as part of a network. I found this really interesting because it shows the difference of consciousness between being awake and being asleep and that even though our brains are active while we are asleep, we are not nearly at the consciousness as we are when we are awake.
