In the 1950s and 1960s, Roger Sperry performed experiments on cats, monkeys, and humans to study functional differences between the two hemispheres of the brain in the United States. The “relatively retarded right hemisphere” by contrast was mute, agraphic, apraxic, and lacking generally in higher cognitive function. Mauriello 2 The Split‐Brain Experiments Typical split‐brain experiments involve presenting the subject with two stimuli simultaneously. In the 1960s, neuroscientist Roger W. Sperry discovered that by cutting the corpus callosum, a large bundle of fibers that connects the right and left hemispheres of the brain, he could reduce seizures in patients with epilepsy. These studies are called "Split-Brain Experiments". Sperry worked with neuropsychologist Michael Gazzaniga who used this effect to demonstrate how each hemisphere could be specialised for different functions. Bogen first suggested to Roger Sperry that he conduct experiments on his so-called "split brained" patients, those whose corpus callosi had been surgically separated to alleviate intractable epilepsy. 1.) Aim: To investigate the functions of separated hemispheres of the brain a severed corpus callosum on the functioning of the 2 brain hemispheres For the next half century, his focus was unwavering and his connection to psychology central to his thinking and research.

Top 10 blogs in 2020 for remote teaching and learning; Dec. 11, 2020 No design or tech skills are necessary - … This essay sketches the import of the work of Sperry and colleagues on patients subjected to callosal section eg., “split brain”. Split-brain patient 'Joe' being tested by Michael Gazzaniga who worked with Roger Sperry The following two links display videos recorded by Baron Wolman of split-brain patients being tested by Michael S. Gazzaniga PhD, one of Roger Sperry’s students. Roger Sperry (who won the Nobel prize in 1981) and Michael Gazzaniga are two neuroscientists who studied patients who had surgery to cut the corpus callosum. To do so he studied the corpus callosum, which is a large bundle of neurons that connects the two hemispheres of the brain. Sperry was imprinted on the mind-brain problem at a very tender age through a chance reading of William James, probably around the age of 10. Roger W. Sperry’s Published Works on Split-Brain research. Sperry wanted to test if his thoughts were true to human split brain patients. The small sample also enabled Sperry to gain more in-depth data See how the patient reacts and try to figure out how come he is acting the way he does. Received the Nobel Prize for Roger Sperry (1913‒1994): Split-brain Research The first experiments into split-brains with humans were conducted in the 1930s in an effort to alleviate severe epilepsy (Sperry, 1975). 11 participants is a very small sample, however Sperry may not have had any control over this - there may not be very many split-brain patients available to study. In the 1950s and 1960s, Roger Sperry performed experiments on cats, monkeys, and humans to study functional differences between the two hemispheres of the brain in the United States. Finally, said Sperry in Stockholm, split-brain research shows that “The whole world of inner experience (the world of the humanities), long rejected by 20th-century scientific materialism, thus becomes recognized and included within the domain of science.” Roger Sperry died in 1994. You should also know that Sperry was awarded the NOBEL PRIZE as a result of his work and findings on the animals. Split-Brain is the lay term to describe a brain that has been severed along the cerebral commissure. Roger Sperry’s Split Brain Experiments (1959–1968) [1] By: Lienhard, Dina A. Keywords: Split Brain [2] Chemoaffinity [3] Brain Function [4] Corpus Callosum [5] In the 1950s and 1960s, Roger Sperry performed experiments on cats, monkeys, andhumans [6] to study functional differences between the two hemispheres of the brain in the United States. The experiments were undertaken on people who had already had their corpus callosum severed as treatment for severe epilepsy. ROGER WOLCOTT SPERRY was born in Hartford, Connecticut on August 20, 1913. (“He deserved it,” Gazzaniga says.) Blog.
