Core Tip
Core Tip: This study presents a lightweight FusedNeXt-based framework for anxiety detection using electroencephalography (EEG) topographic map images. Instead of relying on handcrafted numerical features, alpha, beta, and theta frequency bands were converted into spatial scalp maps and evaluated under the same architecture, data split, and test protocol. The theta band achieved the best overall performance, while the beta band reduced false anxiety predictions in control samples. The proposed model provides competitive accuracy with low computational cost, supporting its potential use in fast EEG-based decision-support systems.
