Fig. (1) Ω-6 delayed motor neuron decline. Mice maintained on the indicated diets commencing at 4 weeks of age were subjected to motor function assays at the indicated ages. The 1000xΩ-3,6 diet (Yip et al., 2013) hastened, while the 10xΩ-6 diet delayed, the 50% Survival point (panel C; p<0.05 for both, ANOVA asterisks) as compared to the standard diet (with no supplementation with either Ω). The 10xΩ-6 diet significantly (p<0.05; Student’s t tests; asterisks) sustained motor function for 1-1.5 weeks longer than the 4xΩ-3,6 as assayed by Motor Deficit (panel B), Quadrant test (panel C, trend lines calculated via Excel) and overall Activity (panel D).
