came an exciting day for people interested in science. From today for a few days, every day we will be learned about the following scientists honored with the Nobel Prize in successive fields of science.
Today’s achievements in the field of physiology and Medicine Nobel Prize awarded to:
- John O’Keefe of the University College Of London (half the prize, about 3.6 million)
- May-Britt Moser and Edvard Moser, marriage researchers from the University of Science and Technology in Trondheim – the half of the remaining amount
The researchers worked independently but on the same issue. Interested in their “internal GPS” of our brain, which enables spatial orientation of man.
In support, the members of the Nobel Committee wrote:
How do we know where we are? How we can find our way from one place to another? And how do we store this information, the next time you traverse the same route, we are able to find it immediately? This year’s Nobel laureates have discovered in the brain positioning system that allows us to orient themselves in space.
John O’Keefe began his research in the sixties XX. century. In 1971, describe the activity observed in the hippocampus and related to body position in space. O’Keefe discovered that they are not reactions to stimuli from the environment – it was an activity associated with the creation of environment maps.
In 2005 , directly continuing research O’Keefe, May-Britt Moser and her husband Edvard discovered another element positioning system: grid cells (called. grid cells). The research also focused on Moserów marriage of Alzheimer’s – it turned out that in the course of the disease is the cells are damaged grid cells of the hippocampus and entorhinal cortex. This may explain the spatial orientation disorder, suffered by patients with Alzheimer’s disease.
Tomorrow we will hear from the Nobel Committee of the winners of the Nobel Prize in physics. It should be equally interesting
