Paralyzed man flies drone using his mind

https://dailygalaxy.com/2025/01/paralyzed-man-flies-drone-using-his-mind/

Turning Thought into Action The participant, paralyzed in all four limbs due to a spinal cord injury, successfully navigated a virtual drone through an obstacle course by imagining specific finger movements. This was made possible through electrodes implanted in his motor cortex, the part of the brain responsible for movement. By visualizing movements such as flexing his thumb or pairing fingers, the participant generated neural signals that the BCI decoded in real time.

This innovative device exemplifies the potential of connecting brain activity with external controls to empower individuals with limited mobility. Researchers aim to use similar systems to help people perform everyday tasks, from typing on a keyboard to controlling robotic limbs.

From Training to Precision The journey to mastering this technology required rigorous training. Initially, the participant practiced syncing his imagined movements with a virtual hand displayed on a screen. He achieved an accuracy rate of hitting up to 76 targets per minute, a testament to the system’s precision and adaptability.

Once proficient, his brain signals were linked to the drone’s navigation system. The participant demonstrated impressive control, guiding the drone through a virtual basketball court with pinpoint accuracy.

Matthew Willsey, a neurosurgeon at the University of Michigan and co-author of the study, likened the process to playing a musical instrument.

A Decade of Progress in BCIsThis success builds on decades of research in brain-computer interfaces. The participant’s electrodes were implanted in 2016 during a previous study, and the team has been refining the technology ever since. Algorithms now allow the BCI to interpret subtle neural patterns, translating them into actionable commands with remarkable speed.

Published in Nature, the study highlights the versatility of BCIs for tasks requiring precise and simultaneous movements. Researchers envision future applications where individuals with paralysis could control multiple functions at once, such as typing and interacting with smart devices.
