Seth argues the brain uses Bayesian inference and predictive modelling [fn 3] to produce a "controlled hallucination" which is a subjective rendering of the inside and outside world. The brain makes predictions, sensory signals keep the predictions tied to their causes, and subjective experiences are created via "top-down" predictions rather ...
Anil Kumar Seth (born 11 June 1972) is a British neuroscientist and professor of Cognitive and Computational Neuroscience at the University of Sussex. A proponent of materialist explanations of consciousness , [ 1 ] he is currently amongst the most cited scholars on the topics of neuroscience and cognitive science globally.
In 2013, Anil Seth proposed that our subjective feeling states, otherwise known as emotions, are generated by predictive models that are actively built out of causal interoceptive appraisals. [19]
Anil Seth defines such models as those that relate brain phenomena such as fast irregular electrical activity and widespread brain activation to properties of consciousness such as qualia. Seth allows for different types of models including mathematical, logical, verbal and conceptual models.
A perceptual illusion that can be precisely controlled is binocular rivalry. Here, a small image, e.g., a horizontal grating, is presented to the left eye, and another image, e.g., a vertical grating, is shown to the corresponding location in the right eye.
However, neuroscientist Anil Seth argued that emphasis on the so-called hard problem is a distraction from what he calls the "real problem": understanding the neurobiology underlying consciousness, namely the neural correlates of various conscious processes. [22] This more modest goal is the focus of most scientists working on consciousness. [133]

Theorists differ in how they relate consciousness to electromagnetism.Electromagnetic field theories (or "EM field theories") of consciousness propose that consciousness results when a brain produces an electromagnetic field with specific characteristics.
