We have demonstrated respiratory chemosensitivity to changes in (H+) and Pco2 of the cerebrospinal fluid (CSF) in the subarachnoid space on the ventrolateral surface of the medulla. Respiratory stimulation was elicited from this region by increased P

Central respiratory drive responding to pH changes was eliminated by bilateral coagulation or cold block of area S (intermediate area) on the ventral medullary surface in 7 anaesthetized cats. Arterial pH, PCO2, and PO2 (4 cats) and the respiratory r

Mathematical Simulation of the Respiratory System. The respiratory system is described as a feedback control system. The controller consists of the peripheral chemoreceptors and the central chemosensitive structures, the respiratory centre in the med

1. Cholinomimetic and adrenomimetic substances were tested on the chemosensitive zones of the ventral surface of the medulla oblongata using a plexiglas ring method. Tidal volume and respiratory frequency, arterial pressure and heart frequency were o

Ventilatory responses to stimulation of chemoreceptor afferents were studied in the anesthetized, spontaneously breathing cat. Short bursts of electrical stimuli were applied, at various times in the inspiratory or expiratory phase of consecutive bre

The mathematical model of the respiratory control system in man of Middendorf and Loeschcke (1976 a, b) opens the possibility to stimulate the constellation of parameters in non-respiratory acidosis. Several investigators agree that the pH in CSF or

The extracellular pH, $$P_{CO_2 } $$ , and [Cl−] at the surface of the brain cortex, expiratory $$P_{CO_2 } $$ and arterial blood pressure were continuously recorded in anaesthetized and artificially ventilated cats. The observations from such a pr
