The paper introduces a platform for label-free electrophysiological live-cell imaging of neuronal networks, demonstrating its capabilities with long-term recordings and analysis tools.

The paper shows that the axon initial segment, not the soma or dendrites, is the main source of the extracellular action potential in neurons.

The paper introduces a new method for segmenting axons from HDMEA data and analyzes neuronal network connectivity, finding that one third of connections are putative chemical synapses and no polychronisation is observed.
