This line of thought came to me the other day and I thought it would be interesting to discuss. The cerebellum is shown in the figure below. From Wikipedia: The cerebellum (Latin for "little brain") is a region of the brain that plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language, and in regulating fear and pleasure responses; its movement-related functions are the most solidly established. The cerebellum does not initiate movement, but it contributes to coordination, precision, and accurate timing. It receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine tune motor activity. Cerebellar damage does not cause paralysis, but instead produces disorders in fine movement, equilibrium, posture, and motor learning. Please Register or Log in to view the hidden image! The cerebellum, by contributing to coordination, precision and timing, within in movement and within speech is the part of the brain behind so many expressions of culture. It is not so much what goes on in the cerebral matter, but rather how this processed in the cerebellum, that defines the movement of the expert dancer or the fine tuned voice of the singer or orator. We can all lip synch from the cerebral but without the cerebellum cooperating, the sound comes out like noise. The cerebellum allows the coordination for video game champions and is needed for all jobs that use hand eye coordination and timing. It connection to fear and pleasure makes peer pressure connected to cerebellum activity. If the cerebellum was less tuned, so much of culture expression, would be uncoordinated like were apes doing it. This would create the impression the cerebral had a disorder even with the mind clear. The actor in his to her speech and action is very dependent on the cerebellum for timing and polish. What we often contribute to cultural smarts; con artist, actually comes from a cerebellum processing high level output. This is part of the social illusion of an extroverted culture.
