As can be seen in the rose histograms for each subject, there are significant differences (P < 0.05 or <0.01) in the topographic representation of memory-guided saccadic endpoints for LG and RG shifts within the same hemisphere.
Note that in Fig. 3, each of the 61 (panel a) or 103 (panel b) responses are shown in approximately correct topographic representation.
In particular, the topographic representation of visual space within a hemisphere differed depending on whether observers shifted their gaze slightly to the left or right of a central point aligned to the midline of the head and body.
Electrophysiological recordings have indicated a topographic representation of visual space in both, the pigeon [36] [40] and the zebra finch [41], but high resolution information is lacking.
We investigated these alternative hypotheses in the barn owl, Tyto alba, an auditory predator whose sound localization is guided by activity on a topographic representation of auditory space in the external nucleus of its inferior colliculus [ICx], [18,19].
We quantified the capacity for reorganization of the topographic representation of area V1 in adult monkeys.
The relationship between neuronal acuity and behavioral performance was assessed in the barn owl (Tyto alba), a nocturnal raptor renowned for its ability to localize sounds and for the topographic representation of auditory space found in the midbrain.
If, in future experiments, one could demonstrate that a topographic representation at some place exists also at the lateral side of the lamina frontalis suprema, this would be an indicator in favour of the view presented by Medina and Reiner [68].

This creates a topographic representation of the visual field in the superficial layers of the SC, also called retinotopy.
