Document Summary
The cerebellum accounts for around 10% of the total brain volume, but more than half of the brains neurons: around 100 billion neurons, mostly of one type. Compares differences between intention and action, and makes appropriate adjustments in motor centers of the cortex. The cerebellar cortex consists of a large number of virtually identical functional units, suggesting that it performs similar functional operations on different inputs. Like a computer with row after row of the same processors: so the cortex must be doing the same type of transformation of all information, even though different parts of the cerebellum have different inputs and outputs. It receives massive input from sensory systems and from systems involved in planning and execution of movement. Input from the somatic sensory system, from the proprioceptive system from the spinal cord (position of arms and legs in space: from sensory regions of the cortex, as well as from the motor.
