Delft University of Technology Jan 31 2025 Key cells in the brain, neurons, form networks by exchanging signals, enabling the brain to learn and adapt at incredible speed. Researchers of the Delft University of Technology in The Netherlands (TU Delft) have developed a 3D-printed 'brain-like environment' where neurons grow similarly to a real brain. Using tiny nanopillars, they mimic the soft neural tissue and the brain extracellular matrix fibers. This model provides new insights into how
