The Bötzinger complex plays an important role in controlling breathing [3] [4] and responding to hypoxia. [5] [6] The Bötzinger complex consists primarily of glycinergic neurons [7] which inhibit respiratory activity. Of the respiratory cycle phases BötC generates post-inspiratory (Post-I) activity and augmenting expiratory (aug-e) activity ...
The pattern of motor stimuli during breathing can be divided into an inhalation stage and an exhalation stage. Inhalation shows a sudden, ramped increase in motor discharge to the respiratory muscles (and the pharyngeal constrictor muscles). [5] Before the end of inhalation, there is a decline in, and end of motor discharge.
Yogis such as B. K. S. Iyengar advocate both inhaling and exhaling through the nose in the practice of yoga, rather than inhaling through the nose and exhaling through the mouth. [16] [17] [18] They tell their students that the "nose is for breathing, the mouth is for eating." [17] [19] [20] [16]
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
The breathing rhythm emerges spontaneously with robust and continuous motor activity measurable on any cranial or spinal motor nerve that innervates breathing related musculature. [ 3 ] [ 4 ] By isolating a rhythmically active newborn rat brainstem-spinal cord in a microsectioning vibratome, Smith and colleagues performed a series of 75 μm ...
It includes Nestor's first-person experiences with breathing. He also worked with scientists at Stanford University whose research suggests that returning to a state of nasal breathing will improve an individual's health. [1] [2] [3] Nestor wrote the book after ten years of researching the subject. [4]
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma .
Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep. It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1] Catathrenia begins with a deep inspiration.
