A paralysed individual, aged 69, has successfully piloted a virtual drone using a brain-computer interface (BCI) that interprets neural signals. This innovative achievement has enabled the participant to navigate a video-game obstacle course by imagining specific finger movements. The breakthrough device, which bridges brain activity and real-time control, demonstrates potential applications for assisting those with mobility challenges to engage in intricate tasks. These developments mark significant progress in the application of BCIs for enhancing motor functions. Breakthrough Detailed in Nature Medicine According to a study published in Nature Medicine, the man, who had been paralysed in all four limbs following a spinal cord injury, controlled the virtual drone using neural signals linked to imagined movements of specific finger groups. The research relied on electrodes implanted in the participant’s left motor cortex, which had been placed during a prior operation in 2016. Algorithms were trained to decode the brain’s signals when he visualised moving his right thumb, different finger pairs, or combinations of them. The researchers reported that the participant initially practised synchronising imagined movements with …
