Fractional anisotropy (FA) values extracted from the left entorhinal cortices. A) Non-Alzheimer’s disease (AD) brain tissue, which is delineated for each entorhinal cortex. B) Preclinical AD brain tissue. C) AD dementia brain tissue. Cyan: Layer I, Red: Layer II, Green: Layer III–VI. D) The histogram shows the FA value of each entorhinal lamina. Error bars indicate standard error of the mean. Asterisks denote significant differences between the mean of the FA values (^*p value with Bonferroni correction <0.05/18; ^**p value with Bonferroni correction <0.005/18).
