Analysis of miniaturization effects and channel selection strategies for EEG sensor networks with application to auditory attention detection.

IEEE Trans Biomed Eng 2019 Apr 17. Epub 2019 Apr 17.

Objective: Concealable, miniaturized electroencephalography ('mini-EEG') recording devices are crucial enablers towards long-term ambulatory EEG monitoring. However, the resulting miniaturization limits the inter-electrode distance and the scalp area that can be covered by a single device. The concept of wireless EEG sensor networks (WESNs) attempts to overcome this limitation by placing a multitude of these mini-EEG devices at various scalp locations. Read More

Multimodal wrist-worn devices for seizure detection and advancing research: Focus on the Empatica wristbands.

Epilepsy Res 2019 Feb 27. Epub 2019 Feb 27.

Empatica, Milan, Italy; Empatica, Cambridge, MA, USA; MIT Media Lab, Massachusetts Institute of Technology, Cambridge, MA, USA.

Wearable automated seizure detection devices offer a high potential to improve seizure management, through continuous ambulatory monitoring, accurate seizure counts, and real-time alerts for prompt intervention. More importantly, these devices can be a life-saving help for people with a higher risk of sudden unexpected death in epilepsy (SUDEP), especially in case of generalized tonic-clonic seizures (GTCS). The Embrace and E4 wristbands (Empatica) are the first commercially available multimodal wristbands that were designed to sense the physiological hallmarks of ongoing GTCS: while Embrace only embeds a machine learning-based detection algorithm, both E4 and Embrace devices are equipped with motion (accelerometers, ACC) and electrodermal activity (EDA) sensors and both the devices received medical clearance (E4 from EU CE, Embrace from EU CE and US FDA).

Addition of frontal EEG to adult home sleep apnea testing: does a more accurate determination of sleep time make a difference?

Sleep Breath 2018 Dec 11;22(4):1179-1188. Epub 2018 Oct 11.

Division of Pulmonary, Critical Care, and Sleep Medicine, New York University School of Medicine, New York, NY, USA.

Rationale: Home sleep apnea testing (HSAT) typically does not include electroencephalogram (EEG) monitoring for sleep assessment. In patients with insomnia and low sleep efficiency, overestimation of the sleep period can result from absence of EEG, which will reduce sleep disordered breathing (SDB) indices and may lead to a false-negative result.

Objective: To validate a single channel frontal EEG for scoring sleep versus wake against full EEG during polysomnography, and then to examine the utility of adding this single channel EEG to standard HSAT to prevent false-negative results. Read More

Neuromonitoring in the ambulatory anesthesia setting: a pro-con discussion.

Curr Opin Anaesthesiol 2018 Dec;31(6):667-672

Department of Anesthesiology.

Purpose Of Review: Various neurologically focused monitoring modalities such as processed electroencephalography (pEEG), tissue/brain oxygenation monitors (SbO2), and even somatosensory evoked responses have been suggested as having the potential to improve the well tolerated and effective delivery of care in the setting of outpatient surgery. The present article will discuss the pros and cons of such monitors in this environment.

Recent Findings: There is a paucity of evidence from rigorous, well designed clinical trials demonstrating that the routine use of any neuromonitoring technique in an ambulatory surgery setting leads to meaningful cost savings or a reduction in morbidity or mortality. Read More

Human emotion classification based on multiple physiological signals by wearable system.

Technol Health Care 2018 ;26(S1):459-469

School of Electrical Engineering and Automaton, Harbin Institute of Technology, Harbin, Heilongjiang, China.

Background: Human emotion classification is traditionally achieved using multi-channel electroencephalogram (EEG) signal, which requires costly equipment and complex classification algorithms.

Objective: The experiments can be implemented in the laboratory environment equipped with high-performance computers for the online analysis; this will hinder the usability in practical applications.

Methods: Considering that other physiological signals are also associated with emotional changes, this paper proposes to use a wearable, wireless system to acquire a single-channel electroencephalogram signal, respiration, electrocardiogram (ECG) signal, and body postures to explore the relationship between these signals and the human emotions.

Surrogate-Based Artifact Removal From Single-Channel EEG.

IEEE Trans Neural Syst Rehabil Eng 2018 03;26(3):540-550

Objective: the recent emergence and success of electroencephalography (EEG) in low-cost portable devices, has opened the door to a new generation of applications processing a small number of EEG channels for health monitoring and brain-computer interfacing. These recordings are, however, contaminated by many sources of noise degrading the signals of interest, thus compromising the interpretation of the underlying brain state. In this paper, we propose a new data-driven algorithm to effectively remove ocular and muscular artifacts from single-channel EEG: the surrogate-based artifact removal (SuBAR). Read More

Characteristics of Epileptiform Discharge Duration and Interdischarge Interval in Genetic Generalized Epilepsies.

Front Neurol 2018 19;9:36. Epub 2018 Feb 19.

Department of Medicine, St. Vincent's Hospital, University of Melbourne, Melbourne, VIC, Australia.

We sought to investigate (1) the characteristics of epileptiform discharge (ED) duration and interdischarge interval (IDI) and (2) the influence of vigilance state on the ED duration and IDI in genetic generalized epilepsy (GGE). In a cohort of patients diagnosed with GGE, 24-h ambulatory EEG recordings were performed prospectively. We then tabulated durations, IDI, and vigilance state in relation to all EDs captured on EEGs.

Cardiac measures of nuclear power plant operator stress during simulated incident and accident scenarios.

Psychophysiology 2018 07 1;55(7):e13071. Epub 2018 Mar 1.

VTT Technical Research Centre of Finland, Espoo, Finland.

Maintaining optimal performance in demanding situations is challenged by stress-induced alterations in performance. Here, we quantified the stress of nuclear power plant (NPP) operators (N = 20) during a full-scale simulator training for incident and accident scenarios. We compared the ambulatory electrocardiography measurements of heart rate (HR) and heart rate variability (HRV), and self-reported stress during baselines and simulated scenarios. Read More

Diagnostic challenges in epilepsy: seizure under-reporting and seizure detection.

Lancet Neurol 2018 03;17(3):279-288

Department of Epileptology, University of Bonn Medical Centre, Bonn, Germany. Electronic address:

Epileptic seizures vary greatly in clinical phenomenology and can markedly affect the patient's quality of life. As therapeutic interventions focus on reduction or elimination of seizures, the accurate documentation of seizure occurrence is essential. However, patient self-evaluation compared with objective evaluation by video-electroencephalography (EEG) monitoring or long-term ambulatory EEG revealed that patients document fewer than 50% of their seizures, on average, and that documentation accuracy varies significantly over time.

Seizure clustering during presurgical electroencephalographic monitoring in children.

Epilepsy Behav 2018 03 3;80:291-295. Epub 2018 Feb 3.

Division of Clinical Neurophysiology, Department of Neurology, Boston Children's Hospital, Harvard Medical School, Boston, MA, United States. Electronic address:

Background: Presurgical evaluation with antiseizure medication tapering in patients with refractory epilepsy places them at risk for seizure clustering or prolonged seizures. We looked at the occurrence of seizure clustering (3 or more seizures within 24h) and prolonged seizures and the factors that influence seizure clustering and affect length of stay (LOS) in pediatric patients during presurgical monitoring.

Methods: We retrospectively reviewed the medical records of all consecutive admissions to the epilepsy monitoring unit (EMU) and included patients undergoing noninvasive presurgical evaluation. Read More
