Obviously, such automatic, almost time-invariant response cannot give rise to perceptual awareness, and is rather involved in smooth pursuit initiation.
In short, these theoretical considerations lead to a partition of stimulus-bound eye movements into pursuit initiation, smooth pursuit and anticipatory pursuit, where each mode of oculomotor control calls on formal additions to the underlying generative model.
In short, these theoretical considerations lead to a partition of stimulus-bound eye movements into pursuit initiation, smooth pursuit and anticipatory pursuit, where each mode of oculomotor control calls on formal additions to the underlying generative model; however, they all use exactly the same scheme and basic principles.
At the subsurface crack initiation site, smooth facets were always present regardless of applied stress level.
In a 2AFC design we investigated the contrast sensitivity for threshold-level stimuli during the initiation of smooth pursuit and during saccades.
Here we explore whether a similar suppression changes the perception of briefly presented low contrast targets during the initiation of smooth pursuit eye movements.
We conclude that almost all available directional information could be extracted from the first few spikes of the response of the neuron, on a time scale comparable with the initiation of smooth pursuit eye movements.
Movement: If you're old enough, recall John Travolta walking down the street to the song "Stayin' Alive" in the opening scene of "Saturday Night Fever". Now imagine a patient with Parkinson's disease, a degenerative brain condition that affects the initiation and smooth completion of movement.
The stimulus for the initiation of smooth pursuit is the velocity of the moving object, i.e. the slippage of the image away from the fovea.
While the value for τe is consistent with the latency for the initiation for smooth pursuit, the value for τt clearly is much smaller.
However, in this model we permitted the time delays for target and eye velocity to differ, and the time delay for target velocity that gave the best fit (20 ms) was much less than the time delay for eye velocity (120 ms) and also much less than the latency for the initiation of smooth pursuit (∼100 ms).
