Figure 3. PLS Analysis Investigating Associations Between Narrative Verbal Memory Scores, Clinical Covariates, and Connectomic Data.

Figure 3

(A) Contributions of clinical covariates and narrative/verbal memory scores to the latent variable (LV). LV accounts for 52% of the total variance and is significant (p = 0.00). LV weights are in gray. Correlations (95% CI) between the behavioral data and the extent to which individual patients express the brain connectivity patterns shown in panel B are in black. Preoperative and postoperative scores for narrative memory, age, type of pathology, and extent of epilepsy are significant behavioral components of the LV. (B) Brain activity associated with the LV. Important nodes include the left temporal lobe in the left insula and right superior frontal gyrus in the theta band, the left fusiform and right temporal lobe in the alpha band, the right precuneus and right pars triangularis in the beta band, and the left temporal lobe and right lingual gyrus in the low gamma band. DEL = delayed; IMM = immediate; PLS = partial least-squares; STORY = narrative/verbal memory for stories.
