Three quite different types of overshoot occur in saccadic eye movements; each has unique characteristics determined by distinct neuronal control patterns. Most saccades have dynamic overshoot; it is more prevalent among, and more prominent in, small saccades. Dynamic overshoot is caused by non-random reversals of the neuronal control signals. It is a(More)
The deep sea, the largest ecosystem on Earth and one of the least studied, harbours high biodiversity and provides a wealth of resources. Although humans have used the oceans for millennia, technological developments now allow exploitation of fisheries resources, hydrocarbons and minerals below 2000 m depth. The remoteness of the deep seafloor has promoted(More)

The human horizontal eye movement system produces quick, precise, conjugate eye movements called saccades. These are important in normal vision. For example, reading tasks exclusively utilize saccadic eye movements. The majority of saccades have dynamic overshoot. The amplitude of this overshoot is independent of saccadic amplitude, and is such that it(More)
A 3-D visual stimulus deflector has been designed so that a subject can view any stimulus pattern or object through it, and the pattern (up to 25 degrees in diameter) can be moved over a range of 40 degrees horizontally and 30 degrees vertically. The optical distance of the object being viewed can be changed over a 15-diopter range, while the brightness and(More)
The relationships between saccadic velocity, duration, and magnitude have been used to prove the normalcy of saccades with intersaccadic intervals of less than 200 ms. Pairs of normal saccades with small intersaccadic intervals will have the second saccade larger or smaller and going in the same or the opposite direction than the first saccade. These normal(More)
PRIMARY OBJECTIVE The aim of this study was to assess the effect of Botulinum toxin A in the management of spastic equinus resulting from traumatic brain injury. RESEARCH DESIGN A before-after intervention design was used without controls. METHODS AND PROCEDURES Subjects were seven patients suffering from traumatic brain injury of average duration 14(More)

Submarine canyons are dramatic and widespread topographic features crossing continental and island margins in all oceans. Canyons can be sites of enhanced organic-matter flux and deposition through entrainment of coastal detrital export, dense shelf-water cascade, channelling of resuspended particulate material and focusing of sediment deposition. Despite(More)
