"Does the primary visual cortex contribute to conscious experience or not? Are areas of the brain that project directly to the prefrontal cortex more relevant than those that do not? Does only a particular subset of cortical neurons play a role? If so, are these neurons characterized by a special property or location? Do cortical neurons need to oscillate at 40 Hz or fire in bursts to contribute to conscious experience? Do different areas of the brain or groups of neurons generate different conscious fragments - a kind of microconsciousness? ... By what mysterious transformation would the firing of neurons located in a particular place in the brain or endowed with a particular biochemical property become subjective experience, while the firing of other neurons would not?"
