A map of brainstem circuits reveals which neurons control the fine motor skills of the arm and hand. Picking up a pen and writing our name or reaching for a fork to eat spaghetti with tomato sauce ...

or the motor itself. In Part 2, we’ll address reading basic to more complex control circuit diagrams and show you how to develop a logical and systematic approach to troubleshooting control circuits.
