Question

Quizplus · Accepted Answer

Cones have higher acuity than rods because there is little convergence in the cone pathways within the retina. This means that each cone communicates with a single bipolar cell and a single ganglion cell, resulting in greater resolution and detail in vision. On the other hand, there is significant convergence in the rod pathways, with many rods communicating with a single bipolar and ganglion cell, leading to less detail in vision but greater sensitivity in low light conditions.
