STOCKHOLM — The Nobel Prize in medicine was given Monday to three experts who built a tool using light to assist solve how the brain performs.
Karl Deisseroth, 54, Peter Hegemann, 71, and Georg Nagel, 73, have carried out checks into light-controlled ion paths and optogenetics.
The Nobel Assembly praised their performance and expressed the method is now being deployed in laboratories around the planet to open the brain’s secrets.
The assembly expressed Deisseroth is working at Stanford University in California, while Hegemann is at Humboldt University in Berlin and Nagel at the University of Würzburg, also in Germany.
Optogenetics opened what the Nobel assembly labeled a fresh era in brain science, the finding of a light-managed switch to turn on and off nerve cells and lines in the brain to better learn how it performs — to start solving the paths that lead to actions and sickness.
It started when Hegemann checked how a single-celled type of green algae can swim toward light. He and Nagel found a particular protein that, when hit by blue light, opens a path to build an electrical current. Putting that protein into alternate cells makes them light-sensitive.
Deisseroth then performed with the gene that manages that protein to build a light-controlled switch for nerve cells in the brains of living mice.
“It’s a very exact set of tools for doing experiments about how the brain performs that remain pretty hard to execute any alternate way,” expressed the University of Pittsburgh’s Jeremy Berg. He stood at the National Institutes of Health in the early 2000s when it gave Deisseroth major funds for “this dream of optogenetics that stood pretty much right on the way it worked out.”
One winner had just gone to bed
Deisseroth, a self-described night owl, expressed he stood up late in his Northern California house performing on papers and emailing his students. He had just gone to lie down when he obtained the call from the Nobel assembly.
“No true sleep stood achieved,” he informed The Associated Press in a phone call an hour after the announcement.
He expressed the upcoming task on his work list stood to pack school food for his youngsters, who were still fast asleep.
“That’s my single duty I hold in the next few hours, to make sure I make their sandwiches,” he expressed.
Thomas Perlmann, the secretary of the medicine committee, expressed he stood able to reach all three winners Monday. The AP’s actions to reach Hegemann and Nagel were not instantly successful.
Medicine prize kicks off Nobels week
The prize stood declared at the Karolinska Institute in Stockholm, launching Nobels week. The prize cash this year is 12 million Swedish kronor (about US$1.2 million).
Last year, the prize went to three experts checking the immune network.
Monday’s medicine prize is followed by the physics prize on Tuesday, chemistry on Wednesday and literature on Thursday.
After Friday’s peace prize is given, the Nobel Memorial Prize in Economic Sciences will be declared on Oct. 12.
The prize cash this year is 12 million Swedish kronor (about $1.2 million), whether for an individual, small group of winners or group.
