Brain regions related to quantum coherence

Common Origins Biological details based on ‘Molecular Biology of the Cell’, Bruce Alberts et al INTRODUCTION: Research since 2007 has shown that quantum coherence is utilised in increasing the efficiency of energy transfer in photosynthetic systems. What has not been emphasised in the discussion of this research is that the mitochondria that produce energy in animals cells probably evolved from the same type of bacteria as the chloroplasts of modern plant systems. Evolution tends to retain Read more […]

Integrated information theory http://en.wikipedia.org/wiki/Integrated_information_theory Summary and review of the above paper INTRODUCTION: Tononi has produced half a theory of consciousness. 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 […]

Into the minds of babes :: Anil Ananthaswamy, based on Stanislas Dehaene, Sid Kouider & Robin Carhart-Harris :: New Scientist, 23 August 2014 Summary and review of the above article Stanislas Dehaene indicates that conscious perception arises through a two stage process. The first stage involves the unconscious processing of an image, and then after about 300 ms a network of brain regions, particularly in the frontal and parietal areas, supports the perception of a conscious image, which Read more […]

His marshmallow test involved leaving young children, typically about four years old, alone in a room with a marshmallow or other goodie. They were told that if they could resist eating it for 15 or so minutes, they could have two instead of one marshmallow. The progress of these children was checked later as young adults. It was found that those who could defer gratification Read more […]
