Chinese scientists have successfully conducted the world’s first interventional brain-computer interface (BCI) experiment on a human subject, marking an advancement in the global development of neurotechnology. This is reported by
CGTN, a partner of TV BRICS.

According to the source, the procedure enabled a 67-year-old man with paralysis to regain partial control over his upper limb through a minimally invasive BCI system.

The patient had suffered six months of left-side paralysis following a cerebral infarction. After undergoing the novel procedure, he regained the ability to perform basic actions such as grasping objects and taking medication with his left arm, a milestone achievement for patients affected by stroke and motor impairment.

Unlike previous BCI methods involving open-skull neurosurgery, the team employed an interventional technique using vascular access.

Since the operation, the implanted system has remained stable, free from complications such as infection or signal degradation. The technique significantly lowers surgical risks while achieving high-fidelity brain signal acquisition. The minimally invasive approach also results in a shorter recovery time and reduced patient trauma.

Experts believe that the recent human trial represents a critical step toward broader clinical applications and paves the way for large-scale rehabilitation programmes targeting stroke survivors and individuals with neuromuscular disorders.
