In this super-short, unlisted YouTube video, we can see something fantastic that happens every day. A neuron just being a neuron.
At 10 nanometers (billionths of a meter) brain cells look pretty huge. This is a neuron going about its day. You can actually see comings and goings of proteins around the cell. This video reveals the reconstruction and assembly of proteins in brain cells. Don Arnold, associate professor of molecular and computational biology at the USC Dornsife College of Letters, Arts and Sciences writes: "Your brain is being disassembled and reassembled every day. One week
from today, your brain will be made up of completely different proteins
than it is today. This video shows the process. We've known that it was
happening, but now we can watch it happen."
According to the source, a "new imaging technique was used to cast new light on how proteins are directed to one of the two types of compartments inside the neuron: the axon or the dendrites. The axon is the region of the cell responsible for transmitting electrical signals to other cells, while the dendrites receive signals from other cells." via Science, Space & Robots
