WebDec 28, 2009 · The respiratory neural network is flexible and can undergo neuronal plasticity. Recent work suggests that neurotrophins and their high-affinity tyrosine kinase (Trk) receptors are involved in mediating plasticity of respiratory motor output elicited by intermittent hypoxia. WebThe elimination of respiratory motor output in the human during and after CMV by means of increased ventilator frequency and V t represents a “resetting” of the respiratory rhythm. Two types of powerful influences are responsible for this resetting effect, as previously documented in anesthetized or sleeping dogs and cats ( 3 , 43 ). hollow knight all boss list

WebLastly, viral tracing studies reveals DMH LepRb neurons project to the arcuate nucleus, periaqueductal gray (PAG), and parabrachial nucleus (PBN). Together, these findings highlight a leptin-dependent suprapontine circuit that, along with NTS LepRb neurons, is likely to participate in matching respiratory motor output to metabolism. WebWeakness or mechanical inefficiency of the respiratory muscles results in a mismatch between central respiratory motor output and achieved ventilation. This mismatch may explain the dyspnea experienced by patients with neuromuscular diseases affecting the respiratory musculature ( 68 ) and patients with respiratory muscle fatigue ( 69 ).
