About the Cover
Cover legend: Well practiced movements can be remarkably precise, but as a quick trip to the neighborhood driving range will make abundantly clear, there are limits to this precision. Each cyan squiggle in the cover image indicates the trajectory of the club's head during a particular golf swing. Like snowflakes caught on a frozen spider web, no two swings will ever be exactly alike. Trial-to-trial behavioral variability is a universal, often frustrating, feature of every movement we make. An article in this week's Journal examines how the neural processing of signals and noise in the cerebellum of monkeys contributes to behavioral variability during smooth tracking eye movements. For more information, see the article by Medina and Lisberger for details (pages 6832–6842).
