Human and Human-Interfaced AI Interactions: Modulation of Human Male Autonomic Nervous System via Pupil Mimicry

open access: yesSensors, 2021
Pupillary alterations in virtual humans induce neurophysiological responses within an observer. Technological advances have enabled rapid developments in artificial intelligence (AI), from verbal systems, to visual AI interfaces with the ability to ...

Cardiac vagal afferent neurotransmission in health and disease: review and knowledge gaps

open access: yesFrontiers in Neuroscience, 2023
The meticulous control of cardiac sympathetic and parasympathetic tone regulates all facets of cardiac function. This precise calibration of cardiac efferent innervation is dependent on sensory information that is relayed from the heart to the central ...

Association of Cardiac Autonomic Function Derangement with Obesity and Glycated Haemoglobin: A Cross-sectional Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2023
Introduction: Hyperglycaemia (as assessed by Glycated haemoglobin (HbA1c)) and obesity lead to the production of advanced glycation end products in blood, which are responsible for damage to the microvasculature, slowly leading to cardiac autonomic ...

Alternate Nostril Breathing at Different Rates and its Influence on Heart Rate Variability in Non Practitioners of Yoga [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2016
Introduction: Heart rate variability is a measure of modulation in autonomic input to the heart and is one of the markers of autonomic functions. Though there are many studies on the long term influence of breathing on HRV (heart rate variability ...

ON THE SPINAL PARASYMPATHETIC. Fifth Article. PHYSIOLOGICAL SIGNIFICANCE OF THE SPINAL PARASYMPATHETIC. THE SPINAL PARASYMPATHETIC AS VASODILATOR FOR THE STOMACH AND INTESTINES [PDF]

open access: yesQuarterly Journal of Experimental Physiology, 1931
Stimulation of the splanchnic after nicotine‐application to the cœliac ganglion and to the superior mesenteric ganglion causes marked dilatation of the vessels of the stomach and intestine. This vasodilatation is usually veiled by the peristaltic contraction of the coat of the stomach and intestine, which is simultaneously produced by stimulation of ...

A new mode of pancreatic islet innervation revealed by live imaging in zebrafish

open access: yeseLife, 2018
Pancreatic islets are innervated by autonomic and sensory nerves that influence their function. Analyzing the innervation process should provide insight into the nerve-endocrine interactions and their roles in development and disease. Here, using in vivo

Optical Imaging of Pancreatic Innervation

open access: yesFrontiers in Endocrinology, 2021
At the time of Ivan Pavlov, pancreatic innervation was studied by looking at pancreas secretions in response to electrical stimulation of nerves.

Heart rate variability, thyroid hormone concentration, and neuropsychological responses in Brazilian navy divers: a case report of diving in Antarctic freezing waters [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2022
Open-water diving in a polar environment is a psychophysiological challenge to the human organism. We evaluated the effect of short-term diving (i.e., 10 min) in Antarctic waters on autonomic cardiac control, thyroid hormone concentration, body ...

Vagus Nerve Cross-Sectional Area in Patients With Parkinson's Disease—An Ultrasound Case-Control Study

open access: yesFrontiers in Neurology, 2021
Background: Vagal parasympathetic neurons are prone to degeneration in Parkinson's disease (PD). High-resolution ultrasound can precisely estimate the cross-sectional (CSA) area of peripheral nerves.
