The Cerebellum

The cerebellum at the back of the neck coordinates muscle motion. The motor area sends a
command to reach for a glass of water. If the cerebellum is well developed, then it intercepts
the muscle signals and modifies them so that the hand slowly accelerates smoothly to start with,
then slows down smoothly as it gets near the glass. If the cerebellum is weak, then the arm may
shoot out awkwardly and knock the glass over.

A good cerebellum action produces...

· Fluid, graceful, cat-like motion.

· Good balance
· Speed of repetitive motion (important for typing speed and playing music)

A weak cerebellum can show up as being awkward, clumsy, falling easily, and typing slowly.

Brain-Intensive Activities

Einstein is often quoted as saying that "We only use 5% of our brain." This is wrong. Many activities
use much more of the brain. (Einstein knew almost nothing about the brain, because at the time
no one knew much.)

When a study was conducted of how different activities used different talents, the results were
surprising. Some activities normally considered "simple" in fact were very brain-intensive, using far
more than 5% of the brain. Some of the highlights are…

1. Cooking

Cooking a large meal, such as a Christmas Dinner for a large family, uses nearly 100% of
the brain. Almost every patch of the brain is firing away, like light bulbs flashing on and off
all over the head.

2. Hockey

American hockey players are often cartooned as dumb hunks of muscle. In fact, hockey is
probably the second most brain-intensive human activity. Cooking needs more talents, but
hockey needs faster-acting talents. It is also mostly right-brain talents without much
language needed.
