– the question of how we have a subjective experience of anything at all – it's not too far from the truth.listing 22 theories based in the biology of the brain. In 2024, operating with a less restrictive scope, US public intellectual Robert KuhnWith so many ideas floating around and inherently elusive subject matter, testing theories has been no easy task. Indeed, debate between proponents of different theories has been vigorous and, at times, acrimonious.
Advocates of these two theories, together with a number of unaligned theorists, generated predictions from the two theories about the kinds of brain activity one would expect to be associated with consciousness.The group agreed that integrated information theory predicts conscious perception should be associated with sustained synchronization and activity of signals in a part of the brain called the posterior cortex.
For example, the team failed to find sustained synchronization within the posterior cortex of the kind predicted by integrated information theory. At the same time, global neuronal workspace theory is challenged by the fact that not all contents of consciousness could be decoded from the prefrontal cortex, and by the failure to find neural ignition when the stimulus was first presented.But although this study wasn't a win for either theory, it was a decisive win for science.
