CPG15 does not affect tectal interneurons. (A) Drawings of interneurons from β-gal– infected animals (left) and CPG15VV-infected animals (right) with a TDBL closest to the mean branch length of each group. (B) The growth rate (TDBL on day 2 – TDBL on day 1) is significantly greater (P < 0.01) for CPG15 projection neurons (n = 17) than control neurons (n = 41). Such a difference in growth rate is not seen between interneurons from control 155 ± 48 μm/day (n = 13) and CPG15VV-infected animals 185 ± 81 μm/day (n = 9) (P > 0.7).
