End Point

As part of an investigation into real-world drawing, eye movements and eye – hand interactions have been recorded for twenty subjects of varying drawing experience drawing simple straight and curved lines and a square. Two modes of eye — hand behaviour were observed. In the first, named ‘close pursuit’, fixations closely followed the pencil with a sequence of small saccades. In the second, named ‘target locking’, a stable fixation was made on the end-point of the line throughout the entire drawing action. Depending on subject and type of line, close pursuit, target locking, or a combination of these modes was used regardless of previous drawing experience. The results are discussed in terms of the role of the eye in the control of the movement trajectory of the hand.

Controversial Nature

This chapter analyses the ways in which the collaborative drama The Travels of the Three English Brothers defends the Sherley brothers’ real-world political endeavours across Europe and Persia through its intertheatrical negotiations. Explaining the political background of those endeavours and their controversial nature, it illustrates how the playwrights liken the Sherleys to the heroes of dramas that had been popular on the early modern stage over the preceding twenty years, in particular Tamburlaine and The Merchant of Venice. It also examines the significance of Francis Beaumont’s specific parody, in The Knight of the Burning Pestle, of an episode in Travels in which the Persian Sophy acts as godfather to the child of Robert Sherley. The chapter concludes with a discussion of the role of playing companies in shaping dramatic output.

Catch Up

The anatomical connection between the frontal eye field and the cerebellar hemispheric lobule VII (H-VII) suggests a potential role of the hemisphere in voluntary eye movement control. To reveal the involvement of the hemisphere in smooth pursuit and saccade control, we made a unilateral lesion around H-VII and examined its effects in three Macaca fuscata that were trained to pursue visually a small target. To the step (3°)-ramp (5–20°/s) target motion, the monkeys usually showed an initial pursuit eye movement at a latency of 80–140 ms and a small catch-up saccade at 140–220 ms that was followed by a postsaccadic pursuit eye movement that roughly matched the ramp target velocity. After unilateral cerebellar hemispheric lesioning, the initial pursuit eye movements were impaired, and the velocities of the postsaccadic pursuit eye movements decreased. The onsets of 5° visually guided saccades to the stationary target were delayed, and their amplitudes showed a tendency of increased trial-to-trial variability but never became hypo- or hypermetric. Similar tendencies were observed in the onsets and amplitudes of catch-up saccades. The adaptation of open-loop smooth pursuit velocity, tested by a step increase in target velocity for a brief period, was impaired. These lesion effects were recognized in all directions, particularly in the ipsiversive direction. A recovery was observed at 4 wk postlesion for some of these lesion effects. These results suggest that the cerebellar hemispheric region around lobule VII is involved in the control of smooth pursuit and saccadic eye movements.
