Alterations in electrodermal activity and cardiac parasympathetic tone during hypnosis [PDF]

open access: yes, 2015
Exploring autonomic nervous system (ANS) changes during hypnosis is critical for understanding the nature and extent of the hypnotic phenomenon and for identifying the mechanisms underlying the effects of hypnosis in different medical conditions.

Autonomic nervous system response to remote ischemic conditioning: heart rate variability assessment

open access: yesBMC Cardiovascular Disorders, 2019
Background Remote ischemic conditioning (RIC) is a procedure applied in a limb for triggering endogenous protective pathways in distant organs, namely brain or heart. The underlying mechanisms of RIC are still not fully understood, and it is hypothesized

Photoplethysmography for Quantitative Assessment of Sympathetic Nerve Activity (SNA) During Cold Stress [PDF]

open access: yes, 2019
The differences in the degree of sympathetic nerve activity (SNA) over cutaneous blood vessels, although known to be more prominent in the periphery than the core vasculature, has not been thoroughly investigated quantitatively.

Anticholinergic Drugs in Nonallergic Rhinitis

open access: yesWorld Allergy Organization Journal, 2009
Background: The parasympathetic nervous system contributes to the pathophysiology of multiple forms of allergic and nonallergic rhinitis. Stimulation of the parasympathetic nervous system leads to glandular activation, which produces watery secretions ...

The binding of botulinum neurotoxins to different peripheral neurons [PDF]

open access: yes, 2017
Botulinum neurotoxins are the most potent toxins known. The double receptor binding modality represents one of the most significant properties of botulinum neurotoxins and largely accounts for their incredible potency and lethality.

Time Series Analysis using Embedding Dimension on Heart Rate Variability [PDF]

open access: yes, 2018
Heart Rate Variability (HRV) is the measurement sequence with one or more visible variables of an underlying dynamic system, whose state changes with time. In practice, it is difficult to know what variables determine the actual dynamic system.
