WebJun 15, 2024 · Pre-Bötzinger complex (PBC) neurons located in mammalian brain are the necessary conditions to produce respiratory rhythm, which has been widely verified experimentally and numerically. At present, one of the two different types of bursting mechanisms found in PBC mainly depends on the calcium-activated of non-specific … The preBötzinger complex, often abbreviated as preBötC, is a functionally and anatomically specialized site in the ventral-lateral region of the lower medulla oblongata (i.e., lower brainstem). The preBötC is part of the ventral respiratory group of respiratory related interneurons. Its foremost function is to … See more The initial description of the preBötC was widely disseminated in a 1991 paper in Science, but its discovery predates that paper by one year. The team was led by Jack L. Feldman and Jeffrey C. Smith at the University of … See more Excitatory (glutamatergic) neurons The rhythm-generating core of preBötC incorporates glutamatergic interneurons that express the … See more The preBötC produces two types of breathing rhythm in the presence of physiological levels of oxygen and carbon dioxide. In See more The exact mechanism of the rhythm generation and transmission to motor nuclei remains controversial and the topic of much research See more The first definition of the preBötC was based largely on functional criteria. If the central neuraxis from pons to lumbar spinal cord is removed from a newborn rodent, then basic neural … See more Anatomical observations advanced understanding of the preBötC by providing specific markers expressed by its constituent neurons, which helped understand its approximate borders. The superset of markers is based largely on neuropeptides and … See more Located within the ventrolateral medulla, the pre-Bötzinger complex contains subnetworks that hold distinct synapses and intrinsic … See more
