The book "Lectures on the work of the cerebral hemispheres" with a handwritten appeal to physiologist Polonsky and an autograph by physiologist Ivan Pavlov

On the title page — "Polonsky N.V. the fruit of my work
Academician Ivan Pavlov in 1927."

Ivan Pavlov is an outstanding physiologist, the first Russian Nobel laureate. He made a significant contribution to the study of reflex activity and the functioning of the cerebral hemispheres. His research has become the basis for many fields of neurophysiology and psychology.

Pavlov is best known for his research on conditioned reflexes. He conducted experiments with dogs, showing how a neutral stimulus can be associated with an unconditional one, which leads to the appearance of a conditioned reflex.

In 1904, Ivan Petrovich received the Nobel Prize for his research on the mechanisms of the digestive glands. His work on digestive physiology was revolutionary and provided a new understanding of how the body works.

The recipient of the donation inscription was Nikolai Vasilyevich Polonsky— a physiologist and Pavlov's student. Polonsky was one of Ivan Petrovich's closest students and colleagues. While working in his laboratory, he participated in the research of conditioned reflexes and brain functions.

The book "Lectures on the work of the cerebral hemispheres" is a scientific legacy that has shaped modern physiology and a number of related fields — biology and medicine. The lectures provide a complete systematic presentation of the results of work in the field of the physiology of the large hemispheres of the dog's brain. It was during the writing of these works that the foundation of such a scientific discipline as the physiology of higher nervous activity was laid.
