Abstract
Our eyes never remain still. Even when we stare at a point, small involuntary movements move our eyes in an imperceptible manner. Researchers agree on the presence of three main contributions to eye movements when we fix the gaze: microsaccades, drifts and tremor. These small movements carry the image across the retina stimulating the photoreceptors and thus avoiding fading. Nowadays it is commonly accepted that these movements can improve the discrimination performance of the retina. In this paper, several retina models with or without fixational eye movements were implemented by mean of RetinaStudio tool to test the feasability of these models to be incorporated in future neuroprosthesis. For this purpose each retina model have been stimulated with the same natural scene sequence of images. Results are discussed from the point of view of a neuroprosthesis development.
