Men of science can anticipate actions using brain activity

Fetching the real life into the brain digital scanner, men of science at The University of Western Ontario from The Centre for Brain and Mind can at present ascertain the action an individual was planning, bare moments ahead that action is actually accomplished.




You can find this discovery in the Journal of Neuroscience.

"This is a considerable step forward in our understanding of how the human brain plans actions," alleged Jason Gallivan, a Western Neuroscience PhD student, who was the first author on the paper.

This was a study that lasted over an year. Human subjects let their brainpower activity scanned applying functional magnetic resonance imaging (fMRI) when they executed hand motions: apprehending the top of an object, seizing the bottom of the object, or simply extending and touching the object. The group discovered that by utilising the signals from numerous brain areas, they could anticipate, better than chance, which of the activities the volunteer was just thinking to do moments later.



"Neuroimaging allows us to look at how action planning unfolds within human brain areas without having to insert electrodes directly into the human brain. This is obviously far less intrusive," explains Western Psychology professor Jody Culham, who was the paper's senior author.

This discovery can be used in prosthetic limbs control. "Being able to predict a human's desired movements using brain signals takes us one step closer to using those signals to control prosthetic limbs in movement-impaired patient populations, like those who suffer from spinal cord injuries or locked-in syndrome." said Gallivan
