AI enables paralyzed man to control robotic arm with brain signals

Researchers from UC San Francisco have achieved an extraordinary breakthrough of brain interface (BCI) technology, allowing individuals with paralysis to control robotic devices only through thought.

This innovation combines artificial intelligence (AI) with neuroscience, allowing a paralyzed man to manipulate the robotic hand by imagining movements, a feat that indicates a significant turning point in restoring autonomy for people with severe motor damage.

Brain-Budel interface: new era of control

Device, known as a computer brain interface (BCI), represents a fusion of advanced AI and neural engineering. The BCI have previously fought for maintaining functionality over a long period, often losing its effectiveness after only one or two days. However, the newly developed BCI set a record functioning flawlessly seven months without the need for great adjustments.

The key lies in the ability of the AI ​​model to adapt to subtle changes in brain activity over time. While individuals repeatedly imagine movements, AI perfects their understanding of these neural signals, allowing more accurate control of robotic devices. Dr. Karunesh Ganguly, a neurologist and professor at UCSF, emphasized that this is an adaptive learning between people and AI critical for achieving life functionality in neuroprostics.

Understanding brain changes: science behind the breakthrough

Research by Dr. Gangaly They discovered that although the form of a national team of brain activity remains consistent, their locations change a bit from day to day. This discovery explains why the previous BCIS quickly lost the ability to interpret neural signals precisely.

To solve this challenge, Gangaly and his team studied a participant who had been paralyzed by a stroke years earlier. The sensors implanted on the surface of his brain recorded neuronic signals as he imagined movements such as capturing or lifting the object. For two weeks, these signals have been used to train the AI ​​model to explain daily shifts in brain activity patterns.

From virtual practice to success in the real world

Initially, the participant practiced the control of a virtual robotic hand that gave feedback on his imagined movements. This training helped perfect his ability to visualize precise actions. Once he moved to the use of a real robot hand, he quickly mastered tasks like lifting blocks, opening of cabinets and even holding a cup under the water sprayer.

Months later, the participant retained his ability to control the robotic hand with minimal reconnection, emphasizing the long -term reliability of this BCI system.

Implications on people with paralysis

This revolutionary technology has deep consequences for individuals with paralysis. Tasks like feeding yourself or regardless of water approach could drastically improve the quality of life. Dr. Ganguly is optimistic about additional AI purification to increase speed and fluidity in movement during the testing of the system in home environments.
