He identifies how recent neuroscience has shown that consciousness is related to parts of the brain on which information convergences. He also grasps that consciousness has to be a fundamental aspect of reality. However, he seems to cling to the idea that it can somehow arise from individual bits of Read more […]

Tononi has calculated an information integration quantity labelled as ‘phi’, which is seen as the threshold for consciousness. This idea appears compatible Read more […]
