The names of the Nobel Prize winners were announced Monday in Stockholm.
“This year’s Nobel laureates have discovered in the brain positioning system, internal GPS + +, which allows us to orient themselves in space” – wrote in support of its decision, the members of the Committee.
As noted by the Committee, from the 20s of the last century spatial orientation has been the subject of experiments. The first component of “cognitive maps” in the brain discovered in 1971. John O’Keefe. He observed that a certain type of neurons in the part of the brain called the hippocampus – “cell site” is always active when the rat is in a particular place of peace. More than 30 years later, in 2005., May-Britt and Edvard Moser discovered grid cells (grid cells). Examining the connections in the hippocampus of rats showed a specific activity of neighboring cells of the brain – entorhinal cortex (entorhinal cortex.)
Similar mechanisms have been observed in humans. In people with Alzheimer’s disease is often at an early stage there is a deterioration of spatial memory. Such people can easily be lost even in a well-known environment. The findings of this year’s Nobel Prize winners may facilitate the understanding of the mechanism of spatial memory impairment observed in this disease.
John O’Keefe from the beginning of his career he was fascinated by the scientific study of the brain in terms of behavior. For many years conducted research in London, but was born in New York City to Irish immigrants. He currently serves as director of the Sainsbury Wellcome Centre in Neural Circuits and Behaviour at University College London. The fact that the Nobel Prize winner learned while working at his desk in his own home in London. “I have an opinion quite patient – said Adam Smith of Nobel Media, referring to the 43 years of his research. – In the beginning most people were skeptical about the idea that you can find in the brain of binding elements with aspects of the environment.”
In turn, Dr. Luke Badowski Copernicus Science Centre believes that the winner of the Nobel medical unveiled another piece of “theory of mind”. Perhaps in the future, thanks to, among others, their discoveries, you will be able to control and influence what we want and what we do not want to remember.
“It was a test so important that they belonged Nobel Prize” – rated in an interview with PAP prof. Jerzy Vetulani from the Institute of Pharmacology, Polish Academy of Sciences. According to him, although the research of this year’s Nobel Prize winners are not yet direct applications in the long run to understand the mechanisms of the brain will make it possible. Effectively prevent aging of the brain and result in rehabilitation after strokes.
Vetulani reminded experiment Briton Richard Frackowiak. The London taxi drivers – who every day make up in your head spatial maps have larger hippocampi than the average Londoners, and the size of this part of the brain is correlated with experience in the profession.
