Tracing Light to the Visual Cortex
Captions available
The idea
Tracing vision means following light from cornea to lens to retina to optic nerve to thalamus to occipital cortex, naming each conversion.
In practice
One photon path worked through in full: refraction at the cornea, focus by the lens, inversion on the retina, transduction by cones, convergence on the optic nerve, the crossing at the chiasm, the relay through the thalamus, and arrival at the occipital lobe. Each step named, including where the image stops being an image.
