Spontaneous Firing Characteristics of Cardiovascular Neurons in the Rostral Ventrolateral Medulla during Somatosympathetic Reflex . 11. Minimal Neuronal Model
Park Jeong-Rae


Abstract
Based on the animal experimental results of the companion paper, describing firing response characteristics of cardiovascular neurons in the rostral ventrolateral medulla during the somatosympathetic reflex, the present study developed a neuronal circuit model to provide an insight into arterial blood pressure regulation. Two different kinds of afferent pathways and also two different types of characteristic neurons are postulated, though they are the simplest necessary and physiological as well. Interconnections are structured so that the model satisfies all experimental outcomes. As a result, possible depressor pathway could be derived. The present model describes neuronal response patterns and interacttions between one neuron and another. While the model explains the current experimental results, it warrants further experimental validation.
