Abstract

In adult animals, the nervous system controls the long-term mean blood pressure. The nucleus of the tractus solitarius (NTS) behaves as a comparator between its rostral afferents (the reference) and the cardioreceptor afferents (the feedback). It is hypothesized that, during ontogeny, the nervous system learns the sympathetic efferents from the chemoreceptor feedback. This process is simulated by a neural network model. In a stable metabolism, the model converges to a state in which all the tissues are irrigated with optimal oxygen and carbon dioxide levels.
