Questions 6-8 refer to the figure below, which represents neurofibrillary tangle densities in neocortical layers in three areas of the brain. 6. What would the neurons, which are represented by the triangles in layer III of area 20, most likely look like? (2 points). 7. Name one characteristic of a neuron in layer III of area 18 that would probably never be represented as a triangle (2 points). 8. What does the pattern of NFT densities tell us about the vulnerability of hierarchical processing in Alzheimer’s Disease? (6 points). 9. Why do you think Alzheimer’s disease is so prevalent?
