Microtubule dynamics in very old neurons. Microtubules are cylindrical structures found in cells, including neurons, that play a crucial role in various cellular processes, such as maintaining cell shape, intracellular transport, and providing structural support. As neurons age, they undergo changes in their cellular structures and functions, including alterations in microtubule dynamics. The video may showcase the visualization of these microtubule dynamics using specialized imaging techniques,
