Such eye movements, made to change the proximal optic array (or retinalimage), cannot rationally be neglected by any attempt to understand visual perception. The case of the retinalimage produced by a distant object (such as a building) of cubical shape is illustrative. When an object, say a boat on the water, moves away, its retinalimage decreases in size. The answer is that the retinalimage is highly correlated with some behaviors in the world and, to that extent, is relevant. For example, some saccade cells might fire during drift periods when the head is free and retinalimage speeds are higher. For one thing, the representational status of the retinalimage is problematic. Retinalimage size confounds physical size and distance, and the retinal spectrum confounds surface spectral reflectance and the illumination spectrum. Hence, there is behavioral evidence that high-frequency fluctuations in retinalimage motion are smoothed out before the signals are transformed into the compensatory turning responses. Three-dimensional representation of retinalimage movement by climbing fiber activity. Yet, these varying aspects of the retinalimage are not wholly irrelevant for our behaving in the world. When it has to return to this location, it compares this snapshot with its current retinalimage in order to determine a home vector. These include the optics of the eye forming the retinalimage, photoreceptor sensitivity change, and postreceptoral neural processes in retina and cortex. This suggests that real retinalimage dynamics can be closely matched with stimuli that simply flash on and off. The input to the model is an image set in the frontal plane (much like a retinalimage). As a result, the contours become less distinct or blurred in the retinalimage. For example, the retinalimage usually changes en masse only when the body or eyes move. Previously, it was found that glucagon amacrine cells respond to defocus in the retinalimage and even to its sign. Indeed, because we have eyes, the retinalimage size relates to the size and distance of an external object. Position 0drift cells have more sustained responses and are activated by slow retinalimage speeds or by a stationary stimulus. This is no different from the long-resolved issue as to why we don't see the world upside down, given that the retinalimage is inverted! These examples are from corpora and from sources on the web.
