Now that you understand the process of adding new receptors, new synapses, and new neurons, let’s see it happen in real life. It is hard to put a microscope and video camera inside your brain, but we can put them around a petri dish. This video is taken by a research team under Dr. Popescu in Illinois, USA. The team put neurons inside a petri dish and filmed them for 24 hours as they reached out and formed networks. Watch the long, thin processes forming a web of connections.
