“René Descartes’ Model of Sensory Perception and the Pineal Gland”

This classic illustration from Descartes’ “Treatise of Man” (1664) attempts to explain how visual perception and physical movement occur via the nervous system. Light rays enter the eyes, converge within the brain, and transmit signals through hollow nerves to the pineal gland — which Descartes believed was the seat of the soul and the center of thought and consciousness. The dotted lines depict how stimuli trigger motor responses, such as raising a finger.
