This study validates an automated seizure detection algorithm for multi-channel neonatal EEG, adapting a previously published method to a dataset with fewer electrodes. The Python-based implementation, SDApy, was applied to EEG recordings from 23 neonates to classify seizure and non-seizure epochs using…
Magnetic nanoparticles (MNP) are of increasing interest for applications in medicine and (bio)technology due to their beneficial properties. Magnetic hyperthermia by heating MNP in tumor tissue with an external alternating magnetic field (AMF), is one of the major fields of research. In a medical setting,…
Introduction: Dry electroencephalography (EEG) allows for recording cortical activity in ecological scenarios with a high channel count, but it is often more prone to artifacts as compared to gel-based EEG. Spatial harmonic analysis (SPHARA) and ICA-based methods (Fingerprint and ARCI) have been separately…

Electrocutaneous stimulation can be employed to alert workers in potentially hazardous situations. Previous parameter studies used TENS electrodes during the developmental process of the electrical warning system. As a step towards more practicability, we now focus on electrocutaneous stimulation through…

Purpose Conventional quantitative susceptibility mapping (QSM) methods rely on simplified physical models that assume isotropic and homogeneous tissue properties, leading to artifacts and inaccuracies in biological tissues. This study aims to develop and evaluate DEEPOLE, a deep learning–based method…
Purpose: The autonomic nervous system interacts with the immune system via the inflammatory response. Heart rate variability (HRV), a marker of autonomic activity, is associated with inflammation, and nosocomial in fections/sepsis, and has clinical implications for the monitoring of at-risk patients.…
Electrocutaneous stimulation can be used to warn workers in hazardous situations. To determine parameters for the operating ranges of such warning systems we investigated the influences of vibrations, temperature, and humidity on the perception, attention, muscle twitch, and intolerance thresholds of…
The detection and quantification of coupling strength and direction are important aspects for achieving a deeper understanding of physiological regulatory processes in the field of network physiology. Due to the limitations of established approaches, we developed directionality indices based on simple…

This study investigates the feasibility of a dry electrode cap design for neonatal electroencephalogram (EEG) recordings. Recordings on a phantom and a real infant are compared between a novel dry electrode cap and a clinically used gel-based electrode cap. The phantom recordings included measuring both…
Die Studie untersucht den Einfluss der Tageszeit auf eine hörbedingte Stressreaktion. Damit schließt sie an Untersuchungen einer Arbeitsgruppe an, die sich mit der Entstehung und Verarbeitung von Stress durch Bewältigung akustischer Diskriminationsaufgaben auseinandersetzen. In dieser Studie wurden 12…
About 80% of the information from interaction with the environment is processed by the human visual system. As people age, the vision quality declines due to physiological and pathological changes. The main factor is the aging progress of the human lens, causing cataracts and increased intraocular stray…
Acoustic or visual warning signals for workers in hazardous situations might fail under loud and/or lowvisibility work situations. A warning system that uses electrocutaneous stimulation can overcome this problem. This study aimed to compare vertical, diagonal, and horizontal current stimulation directions…
Warning of workers in dangerous situations is crucial. With the aim of deriving practical parameters for an electrocutaneous warning stimulation, we explore the design dimensions of pulse intervals, amplitudes, and locations of electrocutaneous stimulation in a study on healthy volunteers. Using biphasic…

Objective. Phrenic nerve stimulation reduces ventilator-induced-diaphragmatic-dysfunction, which is a potential complication of mechanical ventilation. Electromagnetic simulations provide valuable information about the effects of the stimulation and are used to determine appropriate stimulation parameters…
Electroencephalographic (EEG) source localization is a fundamental tool for clinical diagnoses and brain-computer interfaces. We investigate the impact of model complexity on reconstruction accuracy by comparing the widely used three-layer boundary element method (BEM) as an inverse method against a…
The analysis of electroencephalography (EEG)/magnetoencephalography (MEG) functional connectivity has become an important tool in neuroscience. Especially the high time resolution of EEG/MEG enables important insight into the functioning of the human brain. To date, functional connectivity is commonly…
Electrical stimulation (ES) techniques, such as deep brain and transcranial electrical stimulation, have shown promise in alleviating the symptoms of depression and other neurological disorders in vivo . A new noninvasive ES method called temporal interference stimulation (TIS), possesses great potential…
