The posterior visual spatial attention system involves a number of separable computations that allow orienting to visual locations. We have studied one of these computations, inhibition of return, in 3-, 4-, 6-, 12-, and 18--month-old infants and adults. Our results indicate that this computation develops rapidly between 3 and 6 months, in conjunction with the ability to program eye movements to specific locations. These findings demonstrate that an attention computation involving the mid-brain eye movement system develops after the third month of life. We suggest how this development might influence the infant's ability to represent and expect visual objects.

Working memory is a system that keeps limited information on-line for immediate access by cognitive processes. This type of active maintenance is important for everyday life activities. The present study shows that maintaining a location in spatial working memory affects the trajectories of saccadic eye movements toward visual targets, as the eyes deviate away from the remembered location. This finding provides direct evidence for a strong overlap between spatial working memory and the eye movement system. We argue that curvature is the result of the need to inhibit memory-based eye movement activity in the superior colliculus, in order to allow an accurate saccade to the visual target. Whereas previous research has shown that the eyes may deviate away from visually presented stimuli that need to be ignored, we show that the eyes also curve away from remembered stimuli.

Developing Muscle

Oculomotor plant and saccade generator are the basics of the saccadic system. The purpose of this paper is mainly focused on mathematical models of horizontal eye movement system. In this respect, it is presented a model for the mechanics of horizontal eye movement. The oculomotor system is presented incorporates known physiological dynamics and musculotendon complex geometry. Developing muscle strength can be described by a two-component version of the model Hill and consists of a passive and active contractile component. The active component includes force-velocity and force-length characteristics of the muscle. Passive component accounts for elastic and viscous effects. Couple neuronal activation dynamics controls that is appropriate for judder from muscle mechanics.
