Neurophysiological Response Based on Auditory Sense for Brain Modulation Using Monaural Beat

no code implementations15 Nov 2023 Ha-Na Jo, Young-Seok Kweon, Gi-Hwan Shin, Heon-Gyu Kwak, Seong-Whan Lee

For analysis, we calculated the power spectral density (PSD) of EEG for each session and compared them in frequency, time, and five brain regions.

Impact of Nap on Performance in Different Working Memory Tasks Using EEG

no code implementations15 Nov 2023 Gi-Hwan Shin, Young-Seok Kweon, Heon-Gyu Kwak, Ha-Na Jo, Seong-Whan Lee

Electroencephalography (EEG) has been widely used to study the relationship between naps and working memory, yet the effects of naps on distinct working memory tasks remain unclear.

Multi-Signal Reconstruction Using Masked Autoencoder From EEG During Polysomnography

no code implementations14 Nov 2023 Young-Seok Kweon, Gi-Hwan Shin, Heon-Gyu Kwak, Ha-Na Jo, Seong-Whan Lee

Polysomnography (PSG) is an indispensable diagnostic tool in sleep medicine, essential for identifying various sleep disorders.

Changes in Power and Information Flow in Resting-state EEG by Working Memory Process

no code implementations12 Dec 2022 Gi-Hwan Shin, Young-Seok Kweon, Heon-Gyu Kwak

Here, we identified frequency-specific power and information flow patterns among three RS EEG before and after WM encoding and WM retrieval.

Development of Personalized Sleep Induction System based on Mental States

no code implementations12 Dec 2022 Young-Seok Kweon, Gi-Hwan Shin, Heon-Gyu Kwak

We aim to develop a personalized sleep induction system based on mental states using electroencephalogram and auditory stimulation.

Siamese Sleep Transformer For Robust Sleep Stage Scoring With Self-knowledge Distillation and Selective Batch Sampling

no code implementations12 Dec 2022 Heon-Gyu Kwak, Young-Seok Kweon, Gi-Hwan Shin

These results could show that SST extracted effective learning features against the bias of labels in datasets, and the selective batch sampling strategy worked for the model robustness in training.

Self-Knowledge Distillation

Automatic Micro-sleep Detection under Car-driving Simulation Environment using Night-sleep EEG

no code implementations10 Dec 2020 Young-Seok Kweon, Gi-Hwan Shin, Heon-Gyu Kwak, Minji Lee

We pre-trained the U-Net to classify the 5-class sleep stages using night-sleep EEG and used the sleep stages estimated by the U-Net to detect micro-sleep during driving.

Predicting the Transition from Short-term to Long-term Memory based on Deep Neural Network

no code implementations7 Dec 2020 Gi-Hwan Shin, Young-Seok Kweon, Minji Lee

So far, many studies have analyzed electroencephalogram (EEG) signals at encoding to predict later remembered items, but few studies have predicted long-term memory only with EEG signals of successful short-term memory.

Assessment of Unconsciousness for Memory Consolidation Using EEG Signals

no code implementations15 May 2020 Gi-Hwan Shin, Minji Lee, Seong-Whan Lee

Seven participants performed two memory tasks (word-pairs and visuo-spatial) before and after the nap to assess the memory consolidation during unconsciousness.
