RBFOX3 and Alzheimer disease: Stereological neuronal counting of NeuN‐positive cells showed a non‐significant trend for neuronal loss in the two CA1 layers in AD‐tau/Aβ macaques only (Figure S1; stratum pyramidal: Mann‐Whitney test: “Pooled CTL” vs. AD‐tau/sham, p = 0.37; “Pooled CTL” vs. AD‐tau/Aβ, p = 0.19; SRLM: Mann‐Whitney test: “Pooled CTL” vs. AD‐tau/sham, p = 0.31; “Pooled CTL” vs. AD‐tau/Aβ, p = 0.19).
