3D Neurospheroids Reach Cortex-Like Complexity, Outperforming 2D Brain Cell Models

Summary
Parodi and colleagues showed human-derived 3D modular neurospheroids generate far richer network activity than standard 2D cultures, with complexity approaching levels measured in animal cortex.
The gain came from combining 3D structure, cell diversity and modular organization—features the team says better mimic real brain tissue than flat lab-grown cell systems.
The model used induced pluripotent stem cell-derived neurons with tunable excitation-inhibition ratios, letting researchers simulate different brain states and diseases.
High-density microelectrode arrays captured spontaneous and electrically evoked activity across the spheroids, while future work aims to record inside the structures and refine module scaling and interactions.
The advance could make human-derived neural cultures a more physiologically relevant platform for studying brain disorders and testing therapies.
