Developmental and experience-dependent regulation of the low affinity neurotrophins receptor, P75^NTR, in mV1 and bV1. (A) P75^NTR mRNA expression decreased right around eye opening in both mV1 and bV1(ANOVA p < 0.001). (B) DR resulted in a 3-fold increase in P75^NTR expression in bV1, but no significant change in mV1. mRNA expression at each developmental time-point was normalized to values at P10. mRNA expression in DR animals was normalized to expression in animals that were raised during the same time period in a 12 hour light/12 hour dark environment. **p < 0.01
