"If we memorise something shortly, in that case, the working memory areas will be activated. By using the near infrared light we can detect the activation of such the brain area. And we can create the signal, by using the blood flow. So, we can just control the model train, only by thinking.

"This method can be applied to various fields. For example, this brain machine interface is already used in the fields of communication with completely locked in ALS patient".

Ever wished you had the power to move things using just your mind ?
A new technology in Japan that reads brain activity could let you control electronic devices without lifting a finger.
STORYLINE:
Scientists in Japan have developed a "brain-machine interface", which analyses slight changes in the brain's blood flow to detect brain motion and translate it into electric signals.
The technology is being pioneered at Hitachi's Advanced Research Laboratory in Hatoyama, just outside Tokyo.
Patients are fitted with a cap connected by optical fibres to a mapping device, which in turn is linked to a toy train set via a control computer.
Once patients are asked to move a finger, the toy train they are connected to immediately springs forward along the tracks, apparently indicating activity in the brain's frontal cortex.
Monitors show blood flow activity in different parts of the brain: green for low blood flow, or little activity, and pink for high blood flow and activity.
Hideaki Koizumi, a project leader at Hitachi's Advanced Research Laboratory, says they are now able to detect the brain activity responsible for moving the model train.
Underlying Hitachi's brain-machine interface is a technology called optical topography, which sends a small amount of infrared light through the brain's surface to map out changes in blood flow.
While brain-machine interface technology has traditionally focused on medical uses, makers like Hitachi and Honda Motor Co. have been racing to refine the technology for commercial application.
Kozumi says the technology is being already used as a means of communication.
The technology could also be used to assist people operate electric wheelchairs, beds or artificial limbs.
Kozumi says he hopes to use the his "brain interface" to rehabilitate people with disabilities like Amyotrophic lateral sclerosis (ALS), often referred to as "Lou Gehrig's disease," is a progressive neurodegenerative disease which leads to paralysis.
