Progress in neural networks for EEG signal recognition in 2021 [PDF]

open access: yesarXiv, 2021
In recent years, neural networks showed unprecedented growth that ultimately influenced dozens of different industries, including signal processing for the electroencephalography (EEG) process. Electroencephalography, although it appeared in the first half of the 20th century, was not changed the physical principles of work to this day.

An Accurate Sleep Stages Classification Method Based on State Space Model

open access: yesIEEE Access, 2019
The classification of sleep stages is the process which helps to evaluate the quality of sleep and detect the sleep related disorders. Through analyzing the electroencephalography, the sleep stages can be discriminated manually by specialists.

Open Vocabulary Electroencephalography-To-Text Decoding and Zero-shot Sentiment Classification [PDF]

open access: yesarXiv, 2021
State-of-the-art brain-to-text systems have achieved great success in decoding language directly from brain signals using neural networks. However, current approaches are limited to small closed vocabularies which are far from enough for natural communication. In addition, most of the high-performing approaches require data from invasive devices (e.g.,

A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

open access: yesAdvanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.

Reactive microglia are the major source of tumor necrosis factor alpha and contribute to astrocyte dysfunction and acute seizures in experimental temporal lobe epilepsy

open access: yesGlia, Volume 71, Issue 2, Page 168-186, February 2023., 2023
Main Points Microglia become rapidly reactive in temporal lobe epilepsy (TLE). Microglia are major producers of TNFα during status epilepticus, which impairs astrocyte coupling and promotes gliosis. Depletion of microglia attenuates acute seizure activity in TLE.

Cortical activity evoked by inoculation needle prick in infants up to one-year old [PDF]

open access: yes, 2015
Inoculation is one of the first and most common experiences of procedural pain in infancy. However, little is known about how needle puncture pain is processed by the central nervous system in children.

Alterations in microglial morphology concentrate in the habitual sleeping period of the mouse

open access: yesGlia, Volume 71, Issue 2, Page 366-376, February 2023., 2023
Main Points We found regional differences of microglial morphology between the somatosensory cortex (SC), hippocampus (HC) and basal forebrain (BF). Cortical‐, but not HC‐ or BF microglial cell sizes negatively correlate with non‐REM sleep slow wave activity.
