Cortical mouse neurons at 7 days in vitro 7 (DIV7) are well polarized with a single, long, branched axon and shorter dendrites arising from the cell body. The cortical neurons were cultured from E17 m...

Time lapse recording showing the development of neuron polarity in a hippocampal neuron growing in vitro. This recording captures not only the formation of the axon (the longest process, oriented down...
