All of modern society relies upon a seemingly simple but surprisingly complex unit of measurement: the second. But knowing exactly what a “second” is is more complicated than you might think!

In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also describes how neurons are classified both structurally and functionally.

Like an actor's script, a sheet of music instructs a musician on what to play (the pitch) and when to play it (the rhythm). Sheet music may look complicated, but once you've gotten the hang of a few simple elements like notes, bars and...
