    • Based on a magnification factor of 10 mm per degree in mouse V1 (42), 200 mm of cortical distance corresponds to 20° of visual angle. A previous study (26) showed that for most neurons, the preferred size of visual stimulus was <15° in radius, and stimuli beyond this radius suppressed neuronal responses. This suggests that surround suppression for top-down modulation and bottom-up processing occur on similar spatial scales. The same inhibitory circuits could also contribute to decreased receptive field similarity and signal correlation between V1 neurons over ∼200 μm (42).
