This monograph offers a cross-system exchange and cross-modality investigation into brain-heart interplay. Brain-Heart Interplay (BHI) is a highly interdisciplinary scientific topic, which spreads from the physiology of the Central/Autonomous Nervous Systems, especially Central Autonomic Network, to advanced signal processing and modeling for its activity quantification. Motivated by clinical evidence and supported by recent findings in neurophysiology, this monograph first explores the definition of basic Brain-Heart Interplay quantifiers, and then moves onto advanced methods for the assessment of health and disease states. Non-invasive use of brain monitoring techniques, including electroencephalogram and function Magnetic Resonance Imaging, will be described together with heartbeat dynamics monitoring through pulseoximeter and ECG signals.

The audience of this book comprises especially of biomedical engineers and medical doctors with expertise in statistics and/or signal processing. Researchers in the fields of cardiology, neurology, psychiatry, and neuroscience in general may be interested as well.

Diese Monographie bietet einen systemübergreifenden Austausch und eine modalitätsübergreifende Untersuchung des Zusammenspiels von Gehirn und Herz. Das Zusammenspiel von Gehirn und Herz (Brain-Heart Interplay, BHI) ist ein hochgradig interdisziplinäres wissenschaftliches Thema, das sich von der Physiologie des zentralen/autonomen Nervensystems, insbesondere des zentral-autonomen Netzwerks, bis hin zu fortgeschrittener Signalverarbeitung und Modellierung zur Quantifizierung seiner Aktivität erstreckt. Motiviert durch klinische Befunde und unterstützt durch die neuesten Erkenntnisse der Neurophysiologie, untersucht diese Monographie zunächst die Definition grundlegender Quantifizierer des Zusammenspiels von Gehirn und Herz und geht dann zu fortgeschrittenen Methoden für die Bewertung von Gesundheits- und Krankheitszuständen über. Der nicht-invasive Einsatz von Techniken zur Überwachung des Gehirns, einschließlich des Elektroenzephalogramms und der funktionellen Magnetresonanztomographie, wird zusammen mit der Überwachung der Herzschlagdynamik durch Pulsoximeter und EKG-Signale beschrieben.Das Buch richtet sich insbesondere an biomedizinische Ingenieure und Mediziner mit Fachkenntnissen in Statistik und/oder Signalverarbeitung. Aber auch Forscher in den Bereichen Kardiologie, Neurologie, Psychiatrie und Neurowissenschaften im Allgemeinen können sich für dieses Buch interessieren.

This book explores Autonomic Nervous System (ANS) dynamics as investigated through Electrodermal Activity (EDA) processing. It presents groundbreaking research in the technical field of biomedical engineering, especially biomedical signal processing, as well as clinical fields of psychometrics, affective computing, and psychological assessment. This volume describes some of the most complete, effective, and personalized methodologies for extracting data from a non-stationary, nonlinear EDA signal in order to characterize the affective and emotional state of a human subject. These methodologies are underscored by discussion of real-world applications in mood assessment. The text also examines the physiological bases of emotion recognition through noninvasive monitoring of the autonomic nervous system. This is an ideal book for biomedical engineers, physiologists, neuroscientists, engineers, applied mathmeticians, psychiatric and psychological clinicians, and graduate students in these fields.

This book reports on the latest advances in complex and nonlinear cardiovascular physiology aimed at  obtaining reliable, effective markers for the assessment of heartbeat, respiratory, and blood pressure dynamics. The chapters describe in detail methods that have been previously defined in theoretical physics such as entropy, multifractal spectra, and Lyapunov exponents, contextualized within physiological dynamics of cardiovascular control, including autonomic nervous system activity. Additionally, the book discusses several application scenarios of these methods. The text critically reviews the current state-of-the-art research in the field that has led to the description of dedicated experimental protocols and ad-hoc models of complex physiology. This text is ideal for biomedical engineers, physiologists, and neuroscientists.
