Title

"Building the Infinite Brain"

Abstract

Interfacing brains and computers helps advance our understanding of the brain and mind, treat their disorders, and when combined with artificial cognitive frameworks, can push the frontier of human ability. Realizing this goal requires new computer architectures—both close to the brain to process and stimulate neural activity, and far from the brain, to run more complex cognitive frameworks, working together. In this talk, I will present my research on the first distributed brain-computer interfacing architecture, SCALO, which processes neural activity from multiple regions of the brain in real time, while being safe for implantation. SCALO is a template for distributed multi-accelerator systems that must meet extreme design constraints. I will also describe the research into accelerating computationally hard models of human cognition, how this might require leveraging novel accelerators like quantum computers, and outline an end-to-end design connecting these with brain interfaces. Meeting the challenging constraints of brain interfacing and complex cognitive modeling required novel system design, leading to fundamental contributions to computer architecture, and sparking a virtuous cycle of innovation between computer architecture and the brain sciences.
