Your brain in the palm of your hand?
For the first time, a brain scanner powered by a cellphone lets you monitor your neural signals at home or on the go, New Scientist reports.
To create the fully portable Smartphone Brain Scanner, a team led by Jakob Eg Larsen at the Technical University of Denmark hooked up a commercially available EEG headset to a Nokia N900 (watch a quick video intro here).
An EEG, or electroencephalogram, monitors the electrical activity of the brain. Normally, it’s connected wirelessly to a USB receiver plugged into a PC. But with this new system, a phone provides the power.
The smartphone EEG allows researchers to study our brain signals away from labs and hospital waiting rooms and in more natural and comfortable environments. By cutting down the number of hospital visits, the system can also help people with conditions like epilepsy or ADHD.
Some other features:
But other researchers warn, while this home-based system is convenient, it can’t compare with the simulation and data-processing of more sophisticated medical devices.
The work will be presented at Affective Computing and Intelligent Interaction (ACII 2011) conference in Memphis next month.
