1. The Anatomy of Visual Sensation
Retina – Light-sensitive layer at the back of the eyeball
Photoreceptors – Light-sensitive cells in the retina that convert light energy to neural impulses
Rods – Sensitive to dim light but not colors
Cones – Sensitive to colors but not dim light
Fovea – Area of sharpest vision in the retina

2. The Anatomy of Visual Sensation
Optic nerve – Bundle of neurons that carries visual information from the retina to the brain
Blind spot – Point where the optic nerve exits the eye and where there are no photoreceptors

3. Transduction of Light in the Retina

4. Afterimages
Afterimages – Sensations that linger after the stimulus is removed
