Temporal and Nasal RGC Axons Behave Very Differently in the Stripe

question 12

Essay

Temporal and nasal RGC axons behave very differently in the stripe assay with alternating anterior and posterior tectal membranes, as seen in Figure Q5-4. Figure Q5-4
A. What possible interpretations can be drawn from the selective growth of temporal RGC axons in this assay?
B. What possible interpretations can be drawn from the indiscriminate growth of nasal RGC axons in this assay?
