Circadian rhythms in voluntary wheel-running activity in mammals are tightly coupled to the molecular oscillations of a master clock in the brain. As such, these daily rhythms in behavior can be used to study the influence of genetic, pharmacological, and environmental factors on the functioning of this circadian clock.

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

We recently identified a novel Drosophila circadian output, temperature preference rhythm (TPR), in which the preferred temperature in flies rises during the day and falls during the night. TPR is regulated independently from another circadian output, locomotor activity. Here we describe the design and analysis of TPR in Drosophila.

Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA High-quality cardiopulmonary resuscitation (CPR) and defibrillation are the most important interventions for patients with cardiac arrest, and should be the first steps that rescuers perform. This is reflected in the American Heart Association's new "CAB" mnemonic. While rescuers were once taught the "ABCs" of cardiac arrest, they now learn "CAB" -...
FAQs
Cycle duration, breathing rate, and phase relationships provide complementary measures of respiratory timing. Cycle duration shows how long each inhalation-exhalation cycle lasts, while breathing rate summarizes the frequency of cycles. Phase relationships describe how respiratory phases align with other measured events, helping investigators examine coordination between respiration, brain activity, autonomic regulation, or behavior.
Changes in respiratory timing and variability can be compared across behavioral states to examine how breathing regulation relates to arousal, autonomic control, and brain activity. This approach does not treat breathing as isolated from the nervous system; instead, it uses shifts in respiratory patterns as measurable indicators of interactions between physiological state and neural regulation.
Variability captures changes from one respiratory cycle to the next rather than reducing breathing to a single average rate. Examining this variation can help characterize how respiration is regulated under different conditions, including stress, sleep, or altered neurological and psychiatric states. It therefore adds information about respiratory organization that a rate measurement alone may miss.
A typical workflow records airflow, chest movement, abdominal movement, or a combination of these signals. Researchers identify inhalation and exhalation events, determine respiratory timing, and calculate cycle duration, breathing rate, and variability. They then compare these measures across conditions or behavioral states, allowing respiratory changes to be related to neural, autonomic, or behavioral observations.
Researchers can apply the method when they need to relate respiration to brain activity, autonomic regulation, arousal, or coordinated behaviors such as speech and movement. Comparisons across behavioral states also make it useful for investigating sleep and stress responses. The measurements provide a quantitative respiratory framework for studying how neural systems generate and modulate rhythmic behavior.
Altered breathing patterns can support investigations of neurological and psychiatric disorders, stress responses, and sleep-related changes. Analysis may reveal differences in rate, cycle timing, or variability across conditions, while phase relationships can show changes in coordination with behavior or other physiological processes. These outcomes help researchers examine neural circuits involved in generating and modulating rhythmic activity.
