Relationship between Fractional Anisotropy values and episodic delayed recall performance for CBS-Impaired and CBS-Spared groups. Plotted data indicate a positive relationship between FA values and delayed recall performance for the CBS-Impaired group, with the magnitude of this relationship depicted using Pearson's correlation coefficient (r). Correlations between FA value for all selected tracts and delayed recall performance for the CBS-Spared group were nonsignificant (all P-values >0.1). (FA) fractional anisotropy, (CBS-Impaired) Corticobasal Syndrome-Impaired memory (<−1.5 z-score on delayed recall), (CBS-Spared) Corticobasal Syndrome-Spared memory (≥−1.5 z-score on the delayed recall), (SLF) Superior Longitudinal Fasciculus.
