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.

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. From his experiments with cats, Sperry knew that there was no sharing of information from right and the left hemispheres, so he made the monkeys memorize two different scenarios at the same time. From his previous experiments with cats and monkeys, Sperry knew that one, the opposite, hemisphere of the brain would only analyze information from one eye and the hemispheres would not be able to communicate to each other what they saw.

Roger W. Sperry (1913-1994) Roger Wolcott Sperry made titanic contributions to neurobiology [1]. He did so by challenging some of the existing scientific dogmas and making discoveries that revolutionised the fields of neural development and hemispheric specialisation [2], Fig. 1. Sperry was born on the 20th of August 1913 in Hartford ...
