Differences between rods and cones Rods are much more sensitive than cones. They generate large responses to single quanta of light but their response saturates in daylight. Rods are slower than cones (linked to higher amplification). They take longer to respond and their response lasts longer – less temporal sensitivity. Rods are mostly found in the peripheral retina – the
