Foveal neurons of the monkey superior colliculus signal trans-saccadic prediction errors
Fig 4
Elevations of foveal reafferent response strengths with trans-saccadic image inconsistencies for both neurons preferring low and neurons preferring high spatial frequency textures.
(a) We assessed neuron preferences for low or high spatial frequency textures based on their reafferent responses in the control trials. More neurons preferred low spatial frequencies, as might be expected [12,29]. The different colors are used to help in classifying the different neuron groups in b. (b) For the same neurons, we plotted whether they elevated or decreased their reafferent responses on image-flip trials. Neurons with both preferences in a could elevate their reafferent responses with trans-saccadic image inconsistencies. Thus, there was no systematic dependence of the results of Figs 2–3 on neuron preferences. The figure’s underlying data are included in S4 Data.
