7. Translate the text into Russian:

“In other words, each hemisphere [of the

brain] seems to have its own separate and private

sensations; its own perceptions; its own concepts;

and its own impulses to act. . . . Following surgery, each hemisphere also has

thereafter its own separate chain of memories

that are rendered inaccessible to the recall

processes of the other.”

Roger Sperry first became well-known in the specialized area of developmental neurobiology. He devised experiments that helped establish the means by which nerve cells become wired in particular ways in the central nervous system. Sperry is probably best known for his pioneering split-brain research. In the 1950s and 1960s, Sperry devised a number of experiments to test the functions of each hemisphere of the brain. He argued that two separate hemispheres of consciousness could exist under one skull. Sperry pioneered the behavioral investigation of split-brain animals and humans. His experiments and techniques laid the groundwork for constructing a map of mental functions.
