In the second episode of this 12-part podcast series, Tales from the Synapse, neuroscientist Anil Seth describes his research into consciousness, which he describes as “insurance against falling into a single, disciplinary hole.”

Alongside neuroscientists, Seth’s research group at the University of Sussex in Brighton, UK, also includes string theorists, mathematicians and psychologists. The team also collaborates with academics in the arts and humanities.

His 2021 book Being You: A New Science of Consciousness. begins by challenging the idea that consciousness is beyond the reach of science, and concludes with a look at consciousness in non-human animals, before asking if artificial intelligence will one day become both sentient and conscious.

Seth’s own academic career path demonstrates the many disciplines with an interest in consciousness. He began studying physics but transitioned to psychology, computer science and artificial intelligence, the subject of his PhD at Sussex. He returned there to set up his neuroscience group after completing a postdoc at the The Neurosciences Institute in San Diego, California, from 2001-2006.

He admits to an ongoing sense of wonder that that the self is experienced through brain activity, the “tofu-textured electrical wetware inside our skulls” with its “86 billion neurons and 1000 times more connections,” adding: “It seems like a miracle. But that’s the point of science, isn’t it, to preserve the wonder of a phenomenon, but to explain it too?"

Tales from the Synapse is produced in partnership with Nature Neuroscience and introduced by Jean Mary Zarate, a senior editor at the journal. The series features brain scientists from all over the world who talk about their career journeys, collaborations and the societal impact of their research.
