Questions: 103 of 108 Concepts com Multiple Select Question Select all that apply Which are true about cone cells? Cones exhibit less convergence than rods. Cones exhibit more spatial summation than rods. Cones exhibit more convergence than rods. Cones do not exhibit spatial summation.

The correct answers are:

• Cones exhibit less convergence than rods.
• Cones do not exhibit spatial summation.

Explanation for each option:

1. Cones exhibit less convergence than rods.
   This statement is true. In the human retina, cone cells have less convergence compared to rod cells. This means that fewer cone cells synapse onto a single ganglion cell, which allows for higher visual acuity and better detail resolution in bright light conditions.

2. Cones exhibit more spatial summation than rods.
   This statement is false. Rods exhibit more spatial summation than cones. Spatial summation refers to the ability of the visual system to combine signals from multiple photoreceptor cells. Rods, which are more sensitive to low light, have higher spatial summation because many rods converge onto a single ganglion cell, enhancing sensitivity but reducing acuity.

3. Cones exhibit more convergence than rods.
   This statement is false. As mentioned earlier, cones exhibit less convergence than rods. Rods have a higher degree of convergence, which is why they are more sensitive to light but provide less detailed vision.

4. Cones do not exhibit spatial summation.
   This statement is true. Cones have minimal spatial summation compared to rods. This characteristic allows cones to provide high-resolution vision, which is essential for tasks requiring detailed visual information, such as reading and recognizing faces.

In summary, cones exhibit less convergence and do not exhibit spatial summation compared to rods.
