  2. Roger Wolcott Sperry - Wikipedia

    en.wikipedia.org/wiki/Roger_Wolcott_Sperry

    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.

  3. Chemoaffinity hypothesis - Wikipedia

    en.wikipedia.org/wiki/Chemoaffinity_hypothesis

    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.

  4. Corollary discharge theory - Wikipedia

    In doing this he would move the image across his retina. A signal was then sent to the brain saying that the image had moved and because there was no efference copy signal sent as well, his brain perceived motion. [7] The term corollary discharge was finally coined in 1950 by Roger Sperry while doing studies on fish. [8]

  5. Split-brain - Wikipedia

    en.wikipedia.org/wiki/Split-brain

    Roger Sperry and his colleagues pioneered research showing that creating another lesion (done to relieve otherwise untreatable epilepsy), in the connections between the left and right hemispheres, revealed that the right hemisphere can allow people to read, to understand speech, and to say some simple words. Research over the next twenty years ...

  6. Dual consciousness - Wikipedia

    en.wikipedia.org/wiki/Dual_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 ...

  7. Law of specific nerve energies - Wikipedia

    en.wikipedia.org/wiki/Law_of_specific_nerve_energies

    In 1945, Roger Sperry showed that it is the location in the brain to which nerves attach that determines experience. He studied amphibians whose optic nerves cross completely, so that the left eye connects to the right side of the brain and the right eye connects to the left side of the brain. He was able to cut the optic nerves and cause them ...

  8. Functional specialization (brain) - Wikipedia

    en.wikipedia.org/wiki/Functional_specialization...

    During the 1960s, Roger Sperry conducted a natural experiment on epileptic patients who had previously had their corpora callosa cut. The corpus callosum is the area of the brain dedicated to linking both the right and left hemisphere together.

  9. Common coding theory - Wikipedia

    en.wikipedia.org/wiki/Common_coding_theory

    From the year 2000 onwards, a growing number of results have been interpreted in favor of the common coding theory. For instance, one functional MRI study demonstrated that the brain's response to the 2/3 power law of motion (i.e., which dictates a strong coupling between movement curvature and velocity) is much stronger and more widespread tha
