Reasoning about pain and itch neural activity detection

This reasoning chain synthesizes why label-free neuroimaging in anesthetized mice reliably detects brain activity for pain but fails for itch. It cites robust brain oscillations following pain stimuli and rarity of reliable neural patterns to itch, considering both biological and experimental factors.
