Nokia applications have mobile brain scanning capabilities

Now you can 'hold' your brain in your own palm. For the first time, a smartphone-powered scanner allows you to monitor nerve signals on the way.

By attaching a commercially available electroencephalic headset to the Nokia N900 smartphone, Jakob Eg Larsenn and colleagues at the Danish Technical University in Kongens Lyngby have created a complete mobile system.

This is the first time the phone has provided power for an EEG headset that monitors brain electrical activity, Larsen said. Normal headphones will be connected wirelessly to a USB plugged into the computer.

Wear headphones and start the app designed by researchers to create a simplified 3D model of the brain, which lights up like a brain wave and can be rotated with a scan screen. Applications can also connect to a remote server that specializes in digitizing, then display the results on a mobile phone.

"Normally, to do all kinds of EEG measurements, you have to set up a large lab very expensive," Larsen said. "You have to get people in there, isolate and give them specific tasks." Smartphone EEG will allow researchers to consider human brain signals in natural environments such as at home or at work. They can also use other smartphone features to conduct experiments such as displaying images or videos that create specific brain reactions, or monitoring groups of people when they perform a task together.

The system also supports people with epilepsy, neurological disorders, and hyperactivity to reduce the number of hospital visits they need to perform with home conditions.

Arkadiusz Stopczynski, who worked on the project with Larsen, said: " We think that EEG will become a popular thing in your home." "It's much better to go to the lab, sit there for 1 hour to run the EEG and come home."

Gunther Krausz of Schiedlberg, Austria, medical engineering firm G. Tec, which provides EEG systems for researchers, said: 'Realizing the real-time brain system on mobile phones is a great job. ' But as a research tool, he said, phones cannot be compared to specialized medical devices. " You need sophisticated stimulation devices and data processing. " " which cannot make this application alone.
