nervous system anatomy

There are about 85 billion neurons in your brain neurophysiology, and they’re sending electrical signals in your body right now! They tell your eyes to move across this page, interpret the words that you read, maintain your posture physiology ... all in a fraction of a second. In this section we’ll explore this vast, complex system from the cellular to the sensory level.
