Low vagal tone in two rat models of psychopathology involving high or low corticosterone stress responses

Maria del Carmen Sandi Perez, Jocelin Grosse, Damien Sébastien Huzard, Sriparna Ghosal

The two stress-responsive physiological systems, autonomic nervous system (ANS) and hypothalamus-pituitary-adrenal (HPA) axis exert complementary and interrelated actions in the organism. Individuals that suffer stress-related psychopathologies frequently ...

Impact of individual differences in glucocorticoid adaptation to stress on behavior, neurophysiology and metabolism

Damien Sébastien Huzard

The stress system is a key modulator of homeostasis and allows organisms to adapt to environmental changes. Proper survival is dependent on the appropriate stress response, for example initiating food (energy) intake or provoking physical reaction. However ...

Changes in Heart Rate Variability Recorded in Natural Situation with T-Shirt Integrated Sensors and Level of Observed Behavioral Excitation: A Pilot Study of Patients with Intellectual Disabilities and Psychiatric Disorders

Michel Akselrod

Background: The present study investigates the possibilities of using heart rate variability (HRV) parameters as physiological markers that precede increase in observed behavioral excitation of intellectually disabled individuals. The ability to recognize ...

Extraction and Analysis of Short-Time Excursions in RR-interval Time Series

Jean-Marc Vesin, Leila Mirmohamadsadeghi, Sasan Yazdani

RR-interval time series often present impulses corresponding to short-duration increases or decreases in the heart rate, most probably due to bursts in autonomic activity. The time-domain heartrate variability index pNN50 is obviously linked to these spike ...

Respiratory rate estimation from the ECG using an instantaneous frequency tracking algorithm

Jean-Marc Vesin, Leila Mirmohamadsadeghi

Monitoring the respiratory rate (RR) is important in many clinical and non-clinical situations but it is difficult in practice, for existing devices are obtrusive, bulky and expensive. The extraction of the RR from the routinely acquired electrocardiogram ...

Influence of atrial substrate on local capture induced by rapid pacing of atrial fibrillation

Jean-Marc Vesin, Vincent Jacquemet, Alexandru Rusu

Preliminary studies showed that the septum area was the only location allowing local capture of both the atria during rapid pacing of atrial fibrillation (AF) from a single site. The present model-based study investigated the influence of atrial substrate ...
