American-British scientist John
O'Keefe and married Norwegians May-Britt Moser and Edvard Moser won the 2014
Nobel Prize for medicine for discovering the brain's "inner GPS" that
makes it possible to orient ourselves in space and help understand diseases
like Alzheimer's, the award-giving body said on Monday, according to Haaretz
and Reuters.
"The discoveries...have solved
a problem that has occupied philosophers and scientists for centuries,"
the Nobel Assembly at Sweden's Karolinska Institute said in a statement when
awarding the prize of 8 million Swedish crowns (US$1.1 million).
The committee recognized the winners
"for their discoveries of cells that constitute a positioning system in
the brain," according to a press release on the Nobel Prize website.
"In 1971, John O ́Keefe
discovered the first component of this positioning system," wrote the
committee. "He found that a type of nerve cell in an area of the brain
called the hippocampus that was always activated when a rat was at a certain
place in a room. Other nerve cells were activated when the rat was at other
places. O ́Keefe concluded that these “place cells” formed a map of the
room."
According to the committee, the
Mosers, the fifth couple in history to share a Nobel Prize, picked up O'Keefe's
work in 2005.
"They identified another type
of nerve cell, which they called 'grid cells' that generate a coordinate system
and allow for precise positioning and pathfinding," according to the
committee. "Their subsequent research showed how place and grid cells make
it possible to determine position and to navigate."
According to the committee, their
discovery is groundbreaking because it "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 committee will announce the
winner of the physics prize on Tuesday, the chemistry prize winner on Wednesday
and the peace laureate on Friday. The economics prize winner will be announced
next week, while the committee has yet to set a date for the literature prize
winner.
The annual award ceremony is set for
December 10 – the anniversary of Alfred Nobel's death – in Stockholm
Thomson Reuters, which has
accurately forecasted 35 Nobel Prize winners since its inception in 2002,
announced its 2014 "Nobel-class" Citation Laureates last month. Its
short list included David Julius, "for elucidating the molecular workings
of how our nerves process the sensation of pain, opening the way to new
advances in pain management" and two professors from New York's
Rockefeller University for physiology or medicine: James E. Darnell, Jr., an
emeritus professor of the Laboratory of Molecular Cell Biology, and Robert G.
Roeder, a professor at the Laboratory of Biochemistry and Molecular Biology.
Last year, Israeli-born Arieh Warshel and South
African-Israeli Michael Levitt shared a Nobel Prize for chemistry, becoming the
11th and 12th Israelis to garner that honour.
