Going from a retinotopic to a spatiotopic coordinate system for spatial attention.
The perpetual distortions lead to a lack of retinotopic correspondence between the stimulation site and the perceived location of the phosphenes in visual space [28-30].
So, visual depth information must be initially coded in retinotopic space, while that information must be ultimately coded in head-centred and/or body-centred representations.
A recent study has shown that, along the dorsal pathway, the anterior intraparietal area and the ventral premotor cortex extract sensorimotor information from perceptual stimuli, making it possible to detect action possibilities from the information detected through the retinotopic map [33].
For example, evidence from honeybees that approach novel environments from a fixed magnetic direction suggests that magnetic cues may help to organize spatial behaviour, possibly by standardizing the vantage point for retinotopic maps in unfamiliar habitats (Collett & Baron 1994).
Due to the highly retinotopic organisation of these cells in the retina (that is to say, neighbouring objects in the visual field are processed by neighbouring cells in the retina and cortex) the signals derived at this stage are able to contribute towards processing the direction of a moving object.

In the "retinotopic" condition, the FOE of the optic flow stimulus was presented in one of nine locations in a 3x3 grid at 15[degrees] distance each, while the monkey looked at the FP presented in the center of the screen (Figure 1(b)).

Retinotopic distribution of axons continues in optic chiasma
Attention leaves a "retinotopic trace": the retinal position of attention before a saccade can be seen in the same retinal location after a saccade [19].
