Fig 4.
Task-based PLS results from four conditions.
(A) Brain scores associated with visual imagery (LV1) differentiate object, scene, and scenario construction from the control task. Bar graphs display means with 95% bootstrapped confidence intervals. (B) Bootstrap Ratios (BSR) are displayed on a single-subject 1T template ni standard space. Warm colors indicate increased activity during imagery tasks, while cool colors represent increased activity during the control condition. The statistical map is thresholded at BSR = ±2.5.
Fig 5.
Task-based PLS results from the imagery conditions.
(A) Brain scores associated with the first latent variable (LV1) differentiating scene from object construction, and (C) the second LV2 differentiating scenario from both object and scene construction. Bar graphs display means with 95% boot-strapped confidence intervals. (B) Bootstrap Ratios (BSR) are displayed on a single-subject 1T template ni standard space. Warm colours reflect activity during scene construction, whereas cool colours reflect activity during object construction. (D) Warm colours reflect activity during scenario construction, whereas cool colours reflect activity during object and scene construction. The statistical map is thresholded at BSR = ±2.5.

Extracted signal intensities from brain regions associated with autobiographical memory taken from NeuroSynth.
Violin plots display the distribution of individual signal intensities. Box plots display the median and the interquartile range of voxel intensities. *p < .05, **p < .01, ***p < .001.
Fig 7.
Correlations associated with the significant latent variables LV1 (A) & LV2 (C) differentiating object, scene and scenario imagery. Bar graphs in (A) and (C) display means with 95% boot-strapped confidence intervals.(B) and (D) Bootstrap Ratios (BSR) are displayed on a single-subject T1 template in standard space. (B) Warm colours reflect connectivity during object and scene construction. (D) Warm colors reflect connectivity during scene and scenario construction. The statistical map is thresholded at BSR = ±2.0.
