Depression is like a dark cloud that hangs over many people, affecting their daily lives. Just as a skilled detective analyzes clues to solve a mystery, scientists have developed SparNet, a powerful tool for understanding major depressive disorder (MDD) using electroencephalogram (EEG) measurements. By combining advanced deep learning techniques with the unique abilities of SparNet, researchers were able to train the model to identify depression with an incredible accuracy of 94.37%! It’s like having a magnifying glass that can spot even the tiniest details in the brain. The SparNet model uses convolutional filters in different brain regions to learn about space-frequency features in EEG signals, allowing it to distinguish between depressive and normal control subjects. The results of the study not only validate the effectiveness of SparNet but also emphasize the importance of incorporating spatial and frequency domain information to successfully detect depression.

Depression affects many people around the world today and is considered a global problem. Electroencephalogram (EEG) measurement is an appropriate way to understand the underlying mechanisms of major depressive disorder (MDD) to distinguish depression from normal control. With the development of deep learning methods, many researchers have adopted deep learning models to improve the classification accuracy of depression recognition. However, there are few studies on designing convolution filters for spatial and frequency domain feature learning in different brain regions. In this study, SparNet, a convolutional neural network composed of five parallel convolutional filters and the SENet, is proposed to learn EEG space-frequency domain characteristics and distinguish between depressive and normal control. The model is trained and tested by the cross-validation method of subject division. The results show that SparNet achieves a sensitivity of 95.07%, a specificity of 93.66%, and an accuracy of 94.37% in classification. Therefore, our results can conclude that the proposed SparNet model is effective in detecting depression using EEG signals. It also indicates that the combination of spatial information and frequency domain information is an effective way to identify patients with depression.
