Roger Wolcott Sperry pioneered the inception of the chemoaffinity hypothesis following his 1960s experiments on the African clawed frog. [2] He would remove the eye of a frog and reinsert it rotated upside-down—the visual nervous system would eventually repair itself, [3] and the frog would exhibit inverted vision.
Roger Wolcott Sperry (August 20, 1913 – April 17, 1994) was an American neuropsychologist, neurobiologist, cognitive neuroscientist, and Nobel laureate who, together with David Hunter Hubel [1] and Torsten Nils Wiesel, won the 1981 Nobel Prize in Physiology and Medicine for his work with split-brain research.
Germine's theory is similar to other theories of holographic consciousness, but he elaborates on it by drawing on Jason Brown's theory of microgenesis. Microgenetic theory applies an evolutionary paradigm to the development of ideas, concepts, and mental constructs, which Germine applies to theorizing the evolutionary origins of consciousness.
Notable researchers in the field include Roger Sperry, one of the first to publish ideas involving a dual consciousness; and his famous graduate student, Michael Gazzaniga. Their results found a pattern among patients: severing the entire corpus callosum stops the interhemispheric transfer of perceptual, sensory, motor, and other forms of ...
Julian Jaynes hypothesized a bicameral mind theory (which relies heavily on Gazzaniga's research on split-brain patients), where the communication between Wernicke's area and its right-hemisphere analogue was the "bicameral" structure. This structure resulted in voices/images that represented mostly warning and survival instruction, originating ...
Roger Sperry Contribution: Neuropsychologist and Nobel laureate, Sperry's split-brain research contributed to the understanding of consciousness as an emergent property of brain processes. He argued that emergent mental properties have causal efficacy, influencing the lower-level neural processes.
Charles Darwin demonstrates evolution by natural selection using many examples (1859). Louis Pasteur uses S-shaped flasks to prevent spores from contaminating broth. This disproves the theory of Spontaneous generation (1861) extending the rancid meat experiment of Francesco Redi (1668) to the micro scale.
Michael S. Gazzaniga (born December 12, 1939) is an American psychologist who is a professor of psychology at the University of California, Santa Barbara, where he heads the new SAGE Center for the Study of the Mind. [2]
