Auditory Processing under Cross-Modal Visual Load Investigated with Simultaneous EEG-fMRI
Figure 5
Functional connectivity of left auditory cortex (PPI seed region) in different visual WM-load conditions.
The top display reflects the parametrically increasing functional connectivity with core regions from the visual WM-load (p<.05, MC-corrected, k>125). The red circled region survives inclusive masking with the initial GLM testing for a parametric WM.-load increase. Lower displays show task-dependent functional connectivity of left AC in different conditions. All contrasts resulted from a group-level random-effects GLM analyzing effects for PPI interaction parameters (task by seed region) (p<.05, FWE-corrected, k>20).
