Computer Architecture for Brain-Computer Interfaces

摘要

Earlier this year, Elon Musk’sNeuralink demonstrated an implantable brain-computer interface (BCI) capable of recording electrophysiological activity fromseveral thousands of biological neurons with high fidelity and signal resolution. Such implantable BCIs ower avenues to treating debilitating neurological disorders (e.g., they are already being used to predict the onset ofseizures, bouts ofanxiety,depression, and risk ofsuicide),controlling prostheses (e.g., by deducing movement intent and thereby controlling prosthetic limbs that mimic the activity of biological limbs),enhancing memory (e.g., via hippocampal BCIs),turning “thoughts” into speech, and much more.
