Area of Science:

Cognitive Neuroscience
Neuroimaging
Machine Learning

Background:

Traditional brain mapping uses general linear models.
Multivariate pattern analysis (MVPA) and functional connectivity analyses are emerging techniques.
These methods identify cognitive states and brain networks, respectively.

Purpose of the Study:

To introduce a novel analysis combining MVPA and functional connectivity.
To explore insights from mutual constraint within a single model.
To investigate multisensory semantic representations of object concepts.

Main Methods:

Utilized a self-paced multisensory imagery task.
Applied multilayer neural networks to cortical BOLD activity patterns.
Incorporated regional functional connectivity into the models.
Replicated findings using an open fMRI dataset.

Main Results:

Models encoding functional connections showed superior classification accuracy.
These models exhibited more pronounced category-specific impairments after simulated lesions.
The integrated approach yielded parsimonious and biologically plausible models.

Conclusions:

Mutually constrained network analyses offer a powerful approach to brain mapping.
This method enhances model accuracy and biological plausibility.
The findings facilitate discovery in cognitive neuroscience and neuroimaging.
