2. Where are somatosensory areas mainly found?
3. From the nuclei, where next?
- The cortex, first the primary sensory cortex and then to the appropriate cortex for the representation (e.g visual)
- The cortex, first the somatosensory cortex and then to the appropriate cortex for the representation (e.g visual)
- The primary visual cortex
4. 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
5. Which of these options measure electrical and magnetic rather than neural activity in the brain?
