Rods are more sensitive due to convergence; summation of signals from multiple rods means each rod requires less neurotransmitter release and a smaller generator potential to trigger an action potential.
- convergence - summation means each rod must release less neurotransmitter to form action potential - smaller generator potential needed in each rod
