From Organoids to Functional Neural Networks: What Limits Reliability, and How Can We Engineer Toward Intelligence?

Brain organoids reproduce key features of human neural development, yet generating stable and reproducible functional networks remains challenging. This review examines the gap between spontaneous electrical activity and organized network function, focusing on neuronal maturation, batch variability, and synaptic organization. Topics include vascularization and perfusion, the assembly of region-specific organoids into interconnected circuits, and advanced electrophysiological recording technologies. These developments are considered alongside closed-loop stimulation and feedback approaches for investigating learning-like adaptation.
The presentation concludes with an integrated framework linking maturation, circuit assembly, synaptic organization, and functional assessment, highlighting synapse-organizing molecules such as CPTX as potential tools for engineering more reliable and controllable organoid networks.
