Brain-Computer Interface, BCI
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Establishing a direct communication pathway between the brain and external devices. It is divided into invasive (electrodes implanted in the brain) and non-invasive (scalp EEG) types. The goal is to achieve "mind control" and "sensory input." Scaffold role: Physical breakthrough in bandwidth. The biggest bottleneck in human evolution is the "input/output bandwidth being too low" (speaking and typing are too slow). BCI attempts to break this I/O bottleneck and achieve high-bandwidth integration between humans and machines. This is the only path to transcend biological evolution.
SCAFFOLDING EFFECT
Reduce cognitive load
Physical breakthrough in bandwidth. The biggest bottleneck in human evolution is the "input/output bandwidth being too low" (speaking and typing are too slow). BCI attempts to break this I/O bottleneck and achieve high-bandwidth integration between humans and machines. This is the only path to transcend biological evolution.
Anchor fast decisions
Establish a direct pathway between the brain (neural electrical signals) and external devices: invasive methods use cortical electrodes for high-precision signal acquisition/writing, while non-invasive methods use scalp EEG with low invasiveness but low signal-to-noise ratio; the core is decoding neural intent and encoding sensory feedback, breaking through traditional I/O bandwidth.
