First Intracortical BCI (Utah Array)
Connecting silicon directly to the brain.
Explore this event on the interactive timeline →The Utah Intracortical Electrode Array (UIEA) was developed, creating the first standardized silicon-based microelectrode array for Brain-Computer Interfaces.
Key Numbers
- Architecture
- 10x10 Silicon Microelectrodes
Verified Facts
- The array looks like a tiny bed of nails (typically 10x10 silicon spikes) that physically penetrates the brain tissue to record the electrical firing of individual neurons.
- While crude by 2026 Neuralink standards, it proved that direct, high-fidelity neural recording was possible, serving as the foundational architecture for all modern BCIs.
