In a new paper published in Philosophical Transactions of the Royal Society B with Professor Adam Zaidel, we debunk the fallacy of ‘unisensory’ stimulation and discuss why the brain needs a self to sense the world. In a nutshell, we maintain that there is no true ‘unisensory’ stimulation, nor has there ever been. To enable causal inference on multisensory stimuli, the brain must initially learn to discriminate between sensory streams through marginalization—a challenging task given the dimensionality of multisensory signals. We suggest that this challenge is addressed through the implicit learning of a fundamental statistical model of multisensory dependencies, including interoceptive and sensorimotor aspects, which gives rise to the basic sense of Self.
