Conclusions
• Cerebellar lesions produce
– Incoordination & errors not weakness
– Lose ability to anticipate errors
– Lose ability to correct
• Motor learning
– Requires sensory awareness
– Implemented via the descending cortical and
brain stem pathways
• Cognitive and emotional disturbances
– Anatomical connections to prefrontal and
cingulate cortex (via thalamus)
• No single function
– Clearly mostly motor; learning, optimizes
– Functions may apply to cognitive and emotional
behaviors
