Smooth saccades
Webtypes of eye movements, such as during smooth pursuit attempts. Saccadic intrusions are mainly categorized into two types – those with an intersaccadic interval and those without one. In the first case, each abnormal unwanted saccade of the intrusion is separated by a brief interval called the intersaccadic interval (Fig. 2 left). Web1.4 Corrective saccades. An interesting feature of the corrective saccade is that its latency (L2, Fig. 1 A) is only 130 ms (e.g., Becker and Fuchs, 1969 ), leaving only 50 ms for central processing. So built-in is the hypometria of primary saccades that corrective saccades can continue to occur even in the dark (ibid.).
