我们在细胞外记录了pre-Bötzinger复核中的15个吸气前(i)神经元,并测试了它们参与前庭(VN)和喉上(SLN)神经反射以及吞咽和呕吐的情况。I型(9个中的1个)和II型(6个中的1个)前I神经元均可投射到对侧腹呼吸组区。前i神经元在VN和SLN呼吸反射和有效吞咽和呕吐过程中改变了放电;在不同的i前神经元之间观察到不同的反应特性。这些结果表明,前i神经元是一个异质性和多功能的本体球神经元群体。
Fifteen pre-inspiratory (pre-I) neurons were extracellularly recorded in the pre-Bötzinger complex and their involvements in vestibular (VN) and superior laryngeal (SLN) nerve reflexes and in fictive swallowing and vomiting were tested in decerebrated and artificially ventilated cats. Both type I (1 of 9) and type II (1 of 6) pre-I neurons could project to the contralateral ventral respiratory group region. Pre-I neurons changed their firing during VN and SLN respiratory reflexes and fictive swallowing and vomiting; different response properties were observed among individual pre-I neurons. These results suggest that pre-I neurons are a population of heterogeneous and multifunctional propriobulbar neurons.
