The diagram illustrates how rod and cone cells in the retina connect to bipolar neurones and ganglion neurones.
Which of the following statements correctly explains how these synaptic connections determine the sensitivity and visual acuity of the human eye?
Multiple rod cells share a single bipolar neurone, leading to spatial summation which gives high sensitivity in low light, but results in low visual acuity.
Multiple rod cells share a single bipolar neurone, leading to temporal summation which gives low sensitivity in low light, but results in high visual acuity.
Each cone cell synapses with a single bipolar neurone, meaning no spatial summation occurs, which gives high sensitivity in low light and high visual acuity.
Each cone cell synapses with a single bipolar neurone, leading to high synaptic convergence which gives low sensitivity in low light and low visual acuity.
