But human perception isn’t just a passive conveyor belt. It’s heavily top-down. When you imagine an apple (your “mind’s eye”), your brain runs the process in reverse. Your higher-level executive networks and memory centers (the embedding layer) send a signal backward down into your Primary Visual Cortex (V1), forcing those early edge-and-color neurons to fire. You literally simulate the sensory experience. (Fun fact: if this feedback loop is physically missing or disconnected, you have Aphantasia—a complete inability to voluntarily visualize mental imagery [1].)
