London: Scientists have been able to predict human movements just by analysing a person's brain activity, an advance that could pave the way for computers which can be controlled with our mind.
A team of researchers led by Angelika Lingnau, from the Royal Holloway, University of London predicted participants' movements by analysing their brain activity.
The research is the first human study to look at the neural signals of planned actions that are freely chosen by the participant and could be the first step in the development of brain-computer interfaces.
Ms Lingnau and her team used functional magnetic resonance imaging (fMRI) while participants planned and performed simple hand movements inside the scanner.
Crucially, participants freely chose which of three hand movements to select.
Using machine learning algorithms, the researchers then determined whether they were able to predict which movement the participant was going to perform on the basis of the brain activity measured during the planning phase.
"We are very excited by our findings because it is the first time a human study of this kind has been carried out where the participants were able to choose a movement by themselves and were the only ones who knew what they had planned to do," said Ms Lingnau.
"We were successfully able to predict what action they were going to carry out just from analysing their brain signals," she said.
"This opens up huge possibilities for the future including the development of technology you can control with your mind as well as enabling the development of methods for helping those with paralysis to have direct brain control to the affected areas," Ms Lingnau added.
The study was published in the Journal of Neuroscience.
