In rods, rhodopsin breaks down in low light, causing hyperpolarization and an action potential in the bipolar neuron, which transmits the impulse to the brain.
- rhodopsin breaks down at low light intensities - hyperpolarisation - action potential forms in bipolar neurone - impulse passed to brain via bipolar neurone
