WebNov 16, 2016 · Results: The changes in heart rate and respiratory frequency variability from slow-wave sleep to REM sleep in healthy controls were no longer detectable in patients with PD. There were significant increases in the mean (p = 0.006), axial (p = 0.006), and radial diffusivities (p = 0.005) in the medulla oblongata of patients with PD. WebRespiratory Control by the Medulla Oblongata. Brainstem areas in the medulla oblongata and pons contain groups of neurons that are particularly important in regulating ventilation. The ventral respiratory group (VRG) and the dorsal respiratory group (DRG) are located in the medulla oblongata and make up the medullary respiratory center.
