Active Inspiratory-Expiratory Phase Switching Mechanism Exists in the Neonatal Nucleus Parabrachialis
The nucleus parabrachialis complex (NPB) which contained with nucleus parabrachialis lateralis, nucleus parabrachialis medialis and Kölliker-Fuse nucleus of the pons is known as a respiratory modulating center and the NPB plays a crucial role in the inspiratory off-switch (von Euler 1983; Feldman 1986; Bianchi et al. 1995; Alheid et al. 2004; Chamberlin 2004; Dutschmann et al. 2004, 2008). The NPB/KF complex is connected reciprocally to medullary respiratory groups, including the ventral respiratory column and the nucleus tractus solitarii, which serves as the first relay of afferents from pulmonary stretch receptors (Ezure 2004; Ezure and Tanaka 2006; Cohen and Shaw 2004).
