Research and discovery of "inner GPS" of brain

Abstract

Since the 20th century, with the progress of brain science research, scientists have discovered the brain GPS, revealing the mechanism of brain spatial cognition. The discovery process of brain GPS has gone through three stages. In 1971, John O'Keefe discovered the position cells in the hippocampus of the brain, which was the beginning of the research on the GPS in the brain; In 1900, James Rank discovered the head direction cells in the medial entorhinal cortex of the brain, and the research on the GPS in the brain made a breakthrough; In 2005, Edvard I. Moser and his wife discovered grid cells, marking the maturity of the research on GPS in the brain. The discovery of intracerebral GPS not only reveals the spatial cognitive function of the brain at the cellular level, but also provides a theoretical basis for the study of diseases related to the nervous system.
