Functional Connectivity of the Scene Processing Network at Rest Does Not Reliably Predict Human Behavior on Scene...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Neuroimaging

Background:

• Scene perception involves a network of scene-selective brain regions with a posterior-anterior organization.
• Posterior regions link to visual processing, while anterior regions connect to memory and control networks.
• Previous research suggests functional connectivity within this network is crucial for cognitive scene processing.

Purpose of the Study:

• To investigate the relationship between interindividual variations in scene processing abilities and the functional connectivity of the scene network.
• To examine scene recognition, spatial memory, and navigational abilities in relation to brain network connectivity.
• To test the hypothesis that functional connectivity differences underlie behavioral performance in scene processing.

Main Methods:

• Utilized resting-state functional magnetic resonance imaging (fMRI) data from a large-scale public dataset.
• Collected cognitive behavioral measures for scene recognition, spatial memory, and navigation.
• Analyzed resting-state functional connectivity within the scene-selective network.

Main Results:

• Confirmed substantial individual differences in scene recognition, spatial memory, and navigational abilities.
• Replicated the known posterior-anterior bias in functional connectivity within the scene network.
• Did not find consistent associations between interindividual variation in functional connectivity and behavioral performance, contrary to the hypothesis.

Conclusions:

• Individual differences in scene processing abilities exist but are not consistently explained by resting-state functional connectivity within the scene network.
• Further research is needed to understand the role of these connections, possibly using task-based or naturalistic fMRI.
• The findings underscore the complexity of brain mechanisms underlying cognitive scene processing.
