Mirror draw

When the hand doesn’t know what the brain wants…

How to use?

Try copying a simple drawing available in front of you with your hands under the shelf, so you can see what you actually draw only in the mirror. Don’t cheat!

What happens?

Not an easy task, is it? We are able to draw by coordinating our movements with our senses – this called sensorimotor ability. Our muscles are controlled by the feedback of our sensory system. As a result of this when somebody moves his hand to the right, but his eyes see that the hand moved left, the body tries to correct automatically. The coordination between the hand and eyes is confused. Lots of practice can make this task easier, because our brain adapts to changed conditions based on experiences.

Our movements are controlled by our cerebellum (“little brain”). Sensory “input” from our muscles is received here, and this organ is responsible for precisely controlling fine movements and coordinate movements of the head and eyes. When cerebellum is injured, movements become clumsy, slow and uncoordinated.
