The cone pathway is also affected by ApoER2 and VLDLR deficiency. A, The amplitude of synaptic transmission through the cone pathway was enhanced in VLDLR KO (MA, p < 0.05). In addition, there were delayed response intervals in VLDLR KO mice (MA, p < 0.05) and a faster interval in ApoER2-EIG mice (YA, p < 0.05). B, The 30 Hz CFR amplitude was impaired in ApoER2 KOs (MA, p < 0.01) and VLDLR KOs (MA, p < 0.01), with an age-dependent reduction seen in both ApoER2 and VLDLR KOs (p < 0.01). No significant strain- or age-dependent differences were detected in the response interval of 30 Hz cone flicker responses (p > 0.05). Error bars indicate SEM. *p < 0.05 (significance when compared to within age-group wild-type controls indicated by two-tailed Student's t test); #p < 0.05 (significance when MA compared to same YA group indicated by two-tailed Student's t test).
