cerebellum

• What is nystagmus?

  Jerky eye movements
• What connects the cerebellum to the brainstem?

  Three cerebellar peduncles
• What are the characteristics of feedback control in movement?

  It is simple, accurate, slow, and causes oscillations
• What is feedforward control in movement?

  It requires experience and learning to adapt future movement programs
• What is the relationship between complex spikes and movement?

  Complex spikes might signal error in movement
• How do feedback and feedforward control work together?

  They work together to compare sensory input with feedforward commands
• What does the cerebellum send projections to?

  Basal ganglia
• What percentage of the brain's neurons are contained in the cerebellum?

  80%
• Name the three cerebellar nuclei.

  Fastigial, globose (interpositus), and dentate
• What is the function of Purkinje cells?

  They integrate information from mossy and climbing fibers and send inhibitory signals to cerebellar nuclei
• How does motor learning affect complex spikes?

  The rate of complex spikes increases with errors and decreases after learning corrects errors
• What do mossy fibers generate?

  Simple spikes
