Updating the Location of Visual Objects in Space Following Vestibular Stimulation
When updating the location of a visual object in space while moving around, we have to rely on sensory information from different modalities. Retinal signals provide us with a notion of the object’s position on the retina, but we also have to take into account eye position in the head and head position in space. In other words, we perform a coordinate transformation from a retinotopic reference frame via a craniotopic to a spatiotopic reference frame (e.g. Andersen et al. 1993). Human psychophysical studies indicate that these transformations show specific errors under certain conditions, from which we may learn how the brain performs these complex neuronal computations.
