Autonomic Disturbances

Autonomic disturbances are disorders of the autonomic nervous system, which regulates involuntary functions such as heart rate, blood pressure, digestion, sweating, and pupil responses. They arise when communication between central autonomic centers, peripheral nerves, and target organs is disrupted, producing excessive, reduced, or poorly coordinated sympathetic and parasympathetic activity. Symptoms may include dizziness on standing, abnormal heart-rate control, gastrointestinal dysfunction, altered sweating, and bladder problems. In neuroscience, studying autonomic disturbances helps researchers connect neural circuits with visceral regulation, distinguish central from peripheral dysfunction, and evaluate conditions such as autonomic neuropathy, neurodegenerative disease, and dysautonomia.

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...

Standardized, comprehensive and fully quantitative testing of autonomic functions is described. The autonomic tests consist of evaluation of all three major autonomic domains including cardiovagal, adrenergic and sudomotor. The severity and distribution of dysautonomia is quantitated using Composite Autonomic Severity Scores.

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias. Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

A Hemocyte Disturbance Assay to Assess Hemocyte Re-Adhesion to Hematopoietic Pockets

This video demonstrates the hemocyte disturbance assay, evaluating hemocyte re-adhesion in Drosophila larvae's hematopoietic pockets. Mechanical disturbance releases resident hemocytes, elevating circulating hemocyte counts. Post-recovery, re-adherence of resident hemocytes is confirmed, illustrating reversibility.

Autonomic Nervous System

The autonomic nervous system (ANS) is a critical component of the peripheral nervous system, primarily responsible for regulating involuntary bodily functions and maintaining homeostasis. It functions in tandem with the central nervous system (CNS) to seamlessly coordinate various physiological processes without the need for conscious control. The ANS comprises two main divisions: the sympathetic and parasympathetic divisions. These divisions function antagonistically to maintain a dynamic...
