While it is widely accepted that breathing depends on a specific region of the brainstem dubbed the preBotzinger complex (preBotC), the mechanisms responsible for rhythm generation remain unclear. In Chapter 1, we examine the pacemaker hypothesis, which posits that pacemaker properties and/or the...

In fact, FRC may also vary with changes in the frequency of breathing in normal subjects and slight amounts of dLH have consistently been found in COPD patients at rest (see below). The definitions of LH used in this article are summarized in Table 1. Table 1. Definitions of lung ...
To assure clinically realistic airflow conditions in the HFOV model global flow monitoring is conducted at the proximal end of the endotracheal tube and visualised in Fig. 1a over six breathing cycles. During the inspiration phase (e.g., t < 33 ms) flow is sinusoidal as prescribed by...

Dao Yin is a form of exercise combining physical movements, mental focus, and breathing originated in ancient China. In this review, we introduce the history in the development and the scope of Dao Yin, the relationship between Dao Yin with Taoist culture and Qigong, and the potential mechanis...
The Klliker–Fuse nucleus (KF) in the pons regulates the postinspiratory activity during breathing and swallowing. Expiratory decrementing neurons of the Btzinger complex may play a role in the arrest of respiratory activity during swallowing. Swallowing preferentially occurs during the postinspiratory ...
1995; Richter 1996). The motor pattern during normal breathing was considered to consist of three phases: inspiration, post-inspiration, and late expiration (Richter 1996; Richter and Spyer 2001), which can be recognized in the integrated activities of the phrenic and cranial (e.g., ...
Breathing complexity therefore arises from respiratory central pattern generators modulated by peripheral and supra-spinal inputs. Very little is known on the brainstem neural substrates underlying breathing complexity in humans. We used both experimental and theoretical approaches to decipher these mechanisms...
