Retinal visual output undergoes significant feature extraction before reaching the visual cortex.
the verdict
SUPPORTED
the evidence backs this
confidence 89/100
Multiple neuroscientific studies confirm that the retina does not merely act as a passive camera, but actively extracts and transforms visual features through diverse ganglion cell types before the signals reach the visual cortex.
