Figure 4. Neuronal degeneration is accelerated in per⁰¹mutants compared to CS^p and flies with restored per function (per⁰¹{per⁺}) on day 50. (A) Mean number of vacuoles (with SEM) representing neuronal degeneration was significantly higher in per⁰¹mutants compared with wild type CS^p and flies with rescued per. Bars with different superscripts are significantly different at p<0.05, data based on 10-15 heads for each genotype. (B-D) Photomicrographs of representative brain sections of CS^p, per⁰¹, and per⁰¹{per⁺} males. Arrows point to vacuolization.
