2-Minute Neuroscience: The Cochlea

In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss the cochlea. I describe the passage of sound waves through the ear, which leads to the depression of the oval window, a structure found in the wall of the cochlea. I cover the three main cavities in the cochlea: the scala vestibuli, scala media, and scala tympani.
