On May 28, 2026, the Chey Institute and the Korea Foundation for Advanced Studies co-hosted a special lecture at KFAS. Professor Donhee Ham (Harvard University, School of Engineering and Applied Sciences) introduced iMEA (Intracellular Microelectrode Array), a semiconductor-based neural recording platform his team has spent over a decade developing to resolve neuroscience's long-standing precision-versus-scale dilemma. Integrating roughly 4,000 micrometer-scale hole electrodes on a single chip, iMEA captured intracellular signals from up to 97% of electrodes simultaneously in cultured rat neurons, enabling the reconstruction of a functional synaptic map spanning approximately 70,000 connections. Professor Ham's team is now extending this work to in vivo recordings, tackling challenges such as tissue micromotion and immune response. In the discussion moderated by with Professor Chang-Hwan Shin (Korea University, Electrical Engineering), Professor Ham observed that unlike the Von Neumann architecture, the brain integrates memory and computation within a single network—an insight he believes could inform next-generation neuromorphic chip design and ultimately illuminate how the brain learns, remembers, and decides.
