Episode notes
How We See
- Visual experience is a brain phenomenon, not just retinal input.
- We see because retinal ganglion cells communicate with the brain.
Color Vision
- Three retinal proteins absorb light at different frequencies, creating color vision.
- The nervous system compares these signals to understand light's wavelength composition.
Dog Vision
- Dogs and cats have two cone types, limiting their color vision like colorblind humans.
- Dr. Berson had a dog who likely saw reds as oranges.
