1. What makes neurons responsible for transduction suitable for the changing environmental conditions in which we live?
- They have a sliding range that they operate over, so in vision, you can see from one to a million photons
- They have a set range that they uniquely operate over.

2. Which one of these is a modular layer?
3. Functional distinctions in layers correspond to...?
- Lateral differences
- Anatomical differences
- Functional differences
4. What happens after transduction?
- Receptor signals are combined to capture different properties of the physical stimulus. They transform from graded to action potentials
- Receptor signals are combined to capture different properties of the physical stimulus. They transform from action to graded potentials
- Receptor signals are transmitted to the cortex through the different relative pathways
5. How are receptors distributed?
- Non-uniformly. For example, there is a high density cones approx 5 degrees from fovea (good vision), but inside there are 0 (blind spot)
- Non-uniformly. For example, there is a high density cones approx 10 degrees from fovea (blind spot), but inside there are 0 (good vision)
- Uniformly. For example, there is an equal distribution of rods and cones on the neural retina
