Another startling discovery
about how the brain works has won a Nobel prize, this time for revealing how we
know where we are on the planet.
Once it became possible to
see into the brain with imaging devices discoveries like this began
multiplying.
A British-American and a
Norwegian couple share the prize for medicine for showing how the human GPS
works.
Once again it shows that
artificial intelligence, in movie form or real life, has a long way to go to
get even close to mother nature.
"The
discoveries have solved a problem that has occupied philosophers and scientists
for centuries," the Nobel Assembly said.
May-Britt
Moser and Edvard Moser of Norway share the award with U.K.-based John O'Keefe.
In many
ways the discoveries of these scientists and others show the miracle of
neuroplasticity. It already has been shown how the brain can fix itself.
The trio
has shown from examining how the cells in rat brains can tell when the rodents
have moved.
They have
their own “grid,” a sort of way to tell longitude and latitude. They combine
“place” or location cells with “grid” cells, a sort of map.
In the
popular Johnny Depp movie “Transcendence” some people want to get off the
“grid,” one of the most popular words in books and movies these days.
Once on the
grid anyone can be found. Once a brain has data about locations it can do the
same.
The
potential for treating illnesses like Alzheimers cannot be overestimated.
The Nobel
committee said the combination of grid and place cells "constitutes a
comprehensive positioning system, an inner GPS, in the brain. (This system is]
affected in several brain disorders, including dementia and Alzheimer's
disease.”
Having
identified the system it is only a matter of time before scientists and doctors
can find ways to repair and/or boost the GPS system.
Imagine a
doctor being able to download, or upload, a new human navigational operating
system.
O’Keefe is
from the University College London and the Mosers from Norwegian University of
Science and Technology in Trondheim.
“The
discoveries of John O ́Keefe, May‐Britt Moser and Edvard Moser have
solved a problem that has occupied philosophers and scientists for centuries —
how does the brain create a map of the space surrounding us and how can we navigate
our way through a complex environment?” the Nobel Committee said.
“The
discovery of the brain’s positioning system represents a paradigm shift in our
understanding of how ensembles of specialized cells work together to execute
higher cognitive functions,” the release said. “It has opened new avenues for
understanding other cognitive processes, such as memory, thinking and
planning.”
