Revolutionizing Brain Connectivity Analysis with Interpretable Deep Learning
This research introduces FCNet, an innovative deep learning framework designed to analyze spectral directed functional connectivity from EEG data. Unlike traditional methods, FCNet employs an interpretable convolutional neural network to optimally discriminate brain states, providing novel non-linear inflow and outflow measures. By integrating DeepLIFT for explainability, the framework pinpoints the most relevant frequency components and connectivity patterns driving network decisions. Applied to motor imagery tasks at both scalp and cortical levels, FCNet demonstrates superior predictive performance and offers neurophysiologically plausible insights into brain dynamics, capturing connectivity changes with high statistical significance similar to established graph theory measures.

FCNet introduces a novel interpretable Convolutional Neural Network (CNN) that processes directed spectral connectivity. It features a spectral block for frequency-domain analysis and a spatial block that learns non-linear inflow and outflow measures. These measures optimally combine information across brain regions and frequencies, providing superior discrimination of brain states compared to linear graph theory methods.
The framework leverages DeepLIFT, an explanation technique, to reveal which specific frequency contents and connectivity inflow/outflow patterns are most relevant for the network's decisions. This provides crucial insights into the neurophysiological markers of different cognitive states, making the model transparent and trustworthy.
FCNet was rigorously applied to EEG functional connectivity data during motor imagery tasks, analyzed at both scalp and cortex levels. The framework successfully captured known spectral connectivity changes associated with motor imagery, such as increased inflow/outflow in sensorimotor regions during ipsilateral movement imagination, providing results with high statistical significance.

DeepLIFT analysis confirms that alpha and beta band oscillations are most crucial for discriminating motor imagery states, aligning with established neurophysiological findings. FCNet's ability to automatically identify these bands underscores its data-driven power.
FCNet's Impact: Personalized Neurological Analysis
Imagine a patient undergoing rehabilitation for motor function. Current diagnostic tools provide general insights. With FCNet, clinicians could analyze patient-specific EEG functional connectivity, identifying precise, non-linear inflow and outflow patterns and their most relevant frequency components. This level of detail enables personalized treatment plans, monitoring the effectiveness of therapies by tracking changes in these highly discriminative neural network measures. This translates to more targeted interventions and a faster path to recovery for the patient.
