explored how people organize visual information into patterns and forms. Gestalt psychologists noted that the perceived whole is sometimes more than the sum of its parts. A
Photoreceptors
cells that respond to light stimuli
Cones
cone-shaped cells that can distinguish between different wavelengths of light, allowing people to see in color.

rods
highly sensitive to light and allow vision even in dim conditions.
