Which of the following is the incorrect difference between rods and cones?

The transduction of sound waves to action potentials takes place:

1. Within the tectorial membrane as it is stimulated by the hair cells.

2. When hair cells are bent against the tectorial membrane causing them to depolarize and release neurotransmitter molecule that stimulates sensory neurons.

3. As the basilar membrane becomes more permeable to sodium ions and depolarizes, initiating an action potential in sensory neurons.

4. Within the middle ear as the vibration is amplified by the malleus, incus, and stapes.
