SAN FRANCISCO Cheap Asics Womens Shoes , April 30 (Xinhua) -- A game developed by the University of Washington (UW) Center for Game Science in partnership with the Allen Institute for Brain Science enables citizen scientists to produce complete, three-dimensional reconstructions of neurons from different regions of the brain in animals and people.
With the game, known as Mozak, which was launched in November Cheap Asics Shoes , novice players numbering roughly 200 a day and Allen Institute neuroscientists have been able to reconstruct neurons 3.6 times faster than previous methods.
The players have outperformed computers at tracing the complicated shapes of neurons. They can produce reconstructions that are 70 to 90 percent complete, compared to roughly 10 to 20 percent for the most effective computer-generated reconstructions.
Mozak shows players a magnified volumetric image of a neuron, which a key type of brain cell that transmits information throughout the nervous system, and asks the viewer to trace or draw its visible branches Asics White Shoes Online , which can also appear as disconnected dots in more challenging areas of data.
Many neurons have delicate and highly branched structures that human eyes can distinguish far better than computers alone. People also tend to be much better at inferring the likely detailed structure from faint and sometimes discontinuous data. Yet computers are better at performing tedious tasks that can take humans a long time and are faster at reconstructing from clear and continuous data. Mozak brings together people and computing in a new way, to solve this enormous problem together.
"This is not a story about people beating computers because people are using subsets of these computational tools," said Center for Game Science director Zoran Popovic, a professor at the Paul G. Allen School of Computer Science & Engineering. "This is about leveraging the things that computers can do well and the things that people do really well when they're trained Asics Black Shoes Online , forming a symbiotic superpower capable of solving unsolved challenges in science."
The creation of Mozak was inspired partly by the growing needs for analyzing data generated by global projects like the BRAIN initiative, said neuroscientist Jane Roskams, who served on the BRAIN advisory working group.
Until recently, neuroscience labs were doing well to trace about one neuron a week Asics Kids Shoes Online , said Stephen Smith, senior investigator for the Allen Institute for Brain Science. Mozak can speed that progress, but fully understanding neural networks will require tracing many thousands of neurons.

JUBA, Sept. 7 (Xinhua) -- South Sudan on Thursday regretted the untimely decision by the United States to sanction three senior officials from the South Sudanese government Asics Mens Shoes Online , saying it could scuttle ongoing peace efforts in the war-torn country.
Ministry of Foreign Affairs spokesman Mawien Makol told Xinhua that the Wednesday sanctions by the U.S. Department of the Treasury on two government officials and one former top army official, on ground of undermining security and peace in the country, will harm ongoing peace efforts.
"It means that the government is not being recognized by our (U.S.) allies. The U.S. has declared sanctions at the time we are doing utmost best to bring peace to the country," Makol revealed.
Among the sanctioned are the minister of information Michael Makuei Asics Womens Shoes Online , South Sudan army (SPLA) deputy chief of logistics General Reuben Riak, former SPLA chief Paul Malong, and three companies linked to one of the officials.
The decision came at the time the head of the United States Agency for International Development (USAID) Mark Green revealed last week on visiting Juba that the United States was reviewing its policy toward South Sudan.
"Sanctions are not important. What's important is to support the government. It is actually crippling ongoing peace efforts," Makol added.
President Salva Kiir declared a national dialogue late last year to involve various insurgent groups in round table negotiations in Juba on condition they renounced violence.
The dialogue process is ongoing with some fringe militia groups joining Asics Shoes Online , amid intermittent fighting with the main rebel group Sudan People's Liberation Army-in opposition (SPLA-IO) led by exiled former First Vice President Riek Machar.
The United States also urged South Sudan leaders to honor their declared ceasefire, stop harassment of aid workers and engage constructively and seriously in the peace deal revival roadmap declared in June by the East African bloc the Intergovernmental Authority on Development (IGAD).
Makol also called on the United States to provide more support to peace efforts than pursuing sanctions.
"We have still good relations with the U.S., contacts are still there. But we need their support in positive way," he said.
South Sudan descended into violence in December 2013 after political dispute between President Kiir and his former deputy Machar led to fighting that pitied mostly Dinka ethnic soldiers loyal to Kiir against Machar's Nuer ethnic group.
The 2015 peace agreement to end the violence was again violated in July 2016 when the rival factions resumed fighting in the capital Asics White Shoes Sale , forcing Machar to flee into exile.
The conflict has killed tens of thousands of people and displaced millions that have sought refuge in neighboring countries.
