How do you know where your hand is? Kinesthesis
Sense of muscle "tone," and position/motion from the feedback we get from the nerves in our muscles.
How do you know where your eye is going to look? Efference Copy
Copy of efferent motor eye control signal to visual input system. This allows us to move our eyes and not be surprised when the visual image shifts. Importantly, allows us to do eye saccades without getting sick. And is the reason we feel sick when our visual system gets "out of sync."
How do we feel texture? Pressure? Pain?
Different cells for different stimuli
