TL;DR: Self‐organizing maps are shown to be an attractive option in detecting functional connectivity using a model‐free approach and were comparable to results from a reference‐based approach.
Abstract: Low-frequency oscillations (0.08 Hz) have been detected in functional MRI studies, and appear to be synchronized between functionally related areas. A current challenge is to detect these patterns without using an external reference. Self-organizing maps (SOMs) offer a way to automatically group data without requiring a user-biased reference function or region of interest. Resting state func- tional MRI data was classified using a self-organizing map (SOM). Functional connectivity between the left and right motor cortices was detected in five subjects, and was comparable to results from a reference-based approach. SOMs are shown to be an attractive option in detecting functional connectivity using a model-free approach. Hum. Brain Mapp. 20:220 -226, 2003. © 2003 Wiley-Liss, Inc.
