Background:

Cognitive impairment research is advancing, with electroencephalography (EEG) showing promise for early detection in the elderly.
Changes in neural activity and functional connectivity patterns correlate with cognitive decline.
Identifying cognitive states is crucial for timely intervention and management of cognitive impairment.

Purpose of the Study:

To introduce PowerSyncNet, a novel deep learning framework for cognitive state identification using EEG functional connectivity.
To develop a framework that effectively extracts and analyzes functional connectivity features across different frequency bands.
To enhance the accuracy of cognitive state identification compared to existing deep learning methods.

Main Methods:

Developed PowerSyncNet, a framework comprising three modules: Channel-Pair Feature Sequences Builder, Encoder4Band, and Classifier.
Extracted features characterizing functional connectivity across various frequency bands.
Utilized temporal-frequency representations and cross-band information for improved feature clarity.

Main Results:

PowerSyncNet demonstrated superior performance in cognitive state identification on both the CAUEEG and ECED datasets.
The framework effectively captured temporal-frequency representations indicative of cognitive states.
Results indicate enhanced feature clarity through combined cross-band information.

Conclusions:

PowerSyncNet offers a powerful tool for accurate cognitive state identification based on EEG functional connectivity.
The framework facilitates early assessment and timely intervention for individuals with cognitive impairment.
This approach holds significant potential for improving patient outcomes in cognitive decline research.
