Abstract
Sensory neurons innervating the lower airway provide essential feedback information that regulates respiratory physiology. These neurons synapse with second-order neurons in the central nervous system, which project directly or indirectly to the respiratory and autonomic centers. Both primary sensory neurons and second-order neurons within these circuits exhibit significant heterogeneity, and the precise roles of individual neuronal subtypes in coding the airway's internal states and modulating respiratory and autonomic outputs remain incompletely understood. In this review, we summarize recent advances in understanding the neuronal diversity along sensory circuits of the lower airway and their physiological functions. We also highlight the challenges in elucidating the roles of specific neuronal subtypes due to the extensive molecular and anatomical diversity among these neurons. Improving targeting specificity for neuronal manipulation, combined with the development of a comprehensive connectivity map, will be critical for revealing the coding and wiring logics that underlie the precise control of respiratory physiology.
期刊介绍:
Current Opinion in Neurobiology publishes short annotated reviews by leading experts on recent developments in the field of neurobiology. These experts write short reviews describing recent discoveries in this field (in the past 2-5 years), as well as highlighting select individual papers of particular significance.
The journal is thus an important resource allowing researchers and educators to quickly gain an overview and rich understanding of complex and current issues in the field of Neurobiology. The journal takes a unique and valuable approach in focusing each special issue around a topic of scientific and/or societal interest, and then bringing together leading international experts studying that topic, embracing diverse methodologies and perspectives.
Journal Content: The journal consists of 6 issues per year, covering 8 recurring topics every other year in the following categories:
-Neurobiology of Disease-
Neurobiology of Behavior-
Cellular Neuroscience-
Systems Neuroscience-
Developmental Neuroscience-
Neurobiology of Learning and Plasticity-
Molecular Neuroscience-
Computational Neuroscience
