🧠 THE SCIENCE
Bistable Imagery & Border Ownership: This famous portrait shows how a single contour is mapped differently based on top-down mental models.
The young woman's cheek and jawline become the old woman's nose. The young woman's ear is the old woman's eye, and the young woman's neckband represents the old woman's mouth. The brain cannot hold both schemas in focus simultaneously. Once you recognize one face, it is easier to trigger it again, illustrating how neural networks consolidate templates and filter raw inputs.
