Abstract: Understanding evolution and how subcellular events influence complex neuronal networks remains a key challenge in neuroscience. This work introduces a method to simultaneously probe electrical activity at micro- and macroscale levels. The study offers new insights into neural dynamics, first by interfacing neurons with graphene field-effect transistors, then by coupling complementary techniques such as calcium imaging and electrical recordings. This correlative approach holds promise for exploring complex biological systems and bridging nanoscale and mesoscale activities.
