Retinotopic visual receptive fields move
WebOct 27, 2016 · These mismatch receptive fields are aligned to the retinotopic map of visual cortex and are similar in size to visual receptive fields. Thus, neurons with mismatch receptive fields signal local deviations of actual visual flow from visual flow predicted based on self-motion and could therefore underlie the detection of objects moving relative to the … WebDec 11, 2024 · Feedback connections from extrastriate visual areas onto orientation-selective cells in V1 are topographic and extend classic receptive fields to regions of space of up to ~15 dva in diameter 14 ...

Retinotopy (from Greek τόπος, place) is the mapping of visual input from the retina to neurons, particularly those neurons within the visual stream. For clarity, 'retinotopy' can be replaced with 'retinal mapping', and 'retinotopic' with 'retinally mapped'.
