Role of default mode network areas to visual perception
Accumulating evidence implicates regions of the default mode network in perception-related experimental paradigms, especially under ambiguous or noisy conditions. This evidence implies that the default mode network provides top-down information from memory and semantic knowledge to shape the perceptual process.
Fine-scale mapping demonstrates substantial heterogeneity within default mode network nodes in functional responses, connectivity, and cytoarchitecture, making it a challenging system to study but, at the same time, pointing to its integrative role.
The default mode network interacts with the visual system and brain networks that are involved in sensory processing. It also shows extensive subcortical connectivity and has a strong link with the hippocampus, all of which further support its hypothesized integrative role.
