Culturing Primary Cortical Neurons for Live-Imaging.

Primary neuronal cultures allow for in vitro analysis of early developmental processes such as axon pathfinding and growth dynamics. When coupled with methods to visualize and measure microtubule dynamics, this methodology enables an inside look at how the cytoskeleton changes in response to extracellular signaling cues. Here, we describe the culturing conditions and tools required to extract primary cortical neurons from postnatal mouse brains and visualize cytoskeletal components.
