Full-Cortical Brain Interfaces

Full-cortical brain interfaces use surgically implanted electrode arrays that interface directly with the cerebral cortex, achieving high signal fidelity by placing thousands of microscale electrodes in contact with brain tissue. Unlike non-invasive BCIs, these systems capture individual neuron firing patterns and enable bidirectional communication, allowing users to control external devices and receive sensory feedback.

The technology aims to restore lost functions in individuals with paralysis, amputation, or neurological disorders. Advanced systems feature biocompatible materials, flexible substrates, wireless power transmission, and sophisticated signal processing. Beyond medical applications, these interfaces generate high-resolution neural datasets that could accelerate AI development. Key challenges include long-term biocompatibility, stable recordings over years, and developing safe surgical techniques.
