State of Brain Emulation Report 2025

The State of Brain Emulation Report 2025 provides a comprehensive reassessment of the field’s progress since Sandberg and Bostrom’s 2008 Whole Brain Emulation roadmap. The report is organized around three core capabilities required for brain emulation: recording brain function (Neural Dynamics), mapping brain structure (Connectomics), and emulation and embodiment (Computational Neuroscience). It also identifies ongoing challenges and outlines strategic priorities to help the field move forward.
