Common Practices in Clinical Electroencephalography

open access: yesKorean Journal of Clinical Laboratory Science, 2021
Electroencephalography (EEG) provides the most accurate and quickest diagnosis of epilepsy. It is also an important examination for the real-time evaluation of brain function and seizures, no matter where.

Multifractal and Entropy-Based Analysis of Delta Band Neural Activity Reveals Altered Functional Connectivity Dynamics in Schizophrenia

open access: yesFrontiers in Systems Neuroscience, 2020
Dynamic functional connectivity (DFC) was established in the past decade as a potent approach to reveal non-trivial, time-varying properties of neural interactions – such as their multifractality or information content –, that otherwise remain hidden ...

Supervised ANN vs. unsupervised SOM to classify EEG data for BCI: why can GMDH do better? [PDF]

open access: yes, 2013
Construction of a system for measuring the brain activity (electroencephalogram (EEG)) and recognising thinking patterns comprises significant challenges, in addition to the noise and distortion present in any measuring technique.

A real-time wireless wearable electroencephalography system based on Support Vector Machine for encephalopathy daily monitoring

open access: yesInternational Journal of Distributed Sensor Networks, 2018
Wearable electroencephalography systems of out-of-hospital can both provide complementary recordings and offer several benefits over long-term monitoring. However, several limitations were present in these new-born systems, for example, uncomfortable for

Time-varying parametric modelling and time-dependent spectral characterisation with applications to EEG signals using multi-wavelets [PDF]

open access: yes, 2008
A new time-varying autoregressive (TVAR) modelling approach is proposed for nonstationary signal processing and analysis, with application to EEG data modelling and power spectral estimation.

AR-PCA-HMM approach for sensorimotor task classification in EEG-based brain-computer interfaces [PDF]

open access: yes, 2010
We propose an approach based on Hidden Markov models (HMMs) combined with principal component analysis (PCA) for classification of four-class single trial motor imagery EEG data for brain computer interfacing (BCI) purposes. We extract autoregressive (AR)

Protocol for electrophysiological monitoring of carotid endarterectomies. [PDF]

open access: yes, 2010
Near zero stroke rates can be achieved in carotid endarterectomy (CEA) surgery with selective shunting and electrophysiological neuromonitoring. though false negative rates as high as 40% have been reported.

Dissociation of Cerebral Blood Flow and Femoral Artery Blood Pressure Pulsatility After Cardiac Arrest and Resuscitation in a Rodent Model: Implications for Neurological Recovery. [PDF]

open access: yes, 2020
Background Impaired neurological function affects 85% to 90% of cardiac arrest (CA) survivors. Pulsatile blood flow may play an important role in neurological recovery after CA.

Laserlight visual cueing device for freezing of gait in Parkinson's disease: a case study of the biomechanics involved [PDF]

open access: yes, 2015
Background: Freezing of gait (FOG) is a serious gait disorder affecting up to two-thirds of people with Parkinson's disease (PD). Cueing has been explored as a method of generating motor execution using visual transverse lines on the floor.

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.
