WebAnd just like what we talked about with the saccades, it has to use the same final common pathway. For the vertical gaze center in the thalamo-mesencephalic junction, that's cranial nerves III & IV, but in the pons, the parapontine reticular formation and the sixth nerve are for the horizontal gaze. WebAnalysis of ventilatory response to CO2 before and after morphine demonstrated a depression of ventilatory response (49 to 53% of baseline) and occlusion pressure response (35 to 50% of baseline) to CO2, with a requirement for high doses of naloxone (10 mg IV) to reverse the effect.

WebIn the pons, a dorsal region, including the nucleus of cranial nerve VI, and portions of the parapontine reticular formation showed volume loss (Figure 1B, row 3; Table 4). The left caudate and right thalamus were also atrophied relative to controls. The paramedian pontine reticular formation, also known as PPRF or paraabducens nucleus, is part of the pontine reticular formation, a brain region without clearly defined borders in the center of the pons. It is involved in the coordination of eye movements, particularly horizontal gaze and saccades. pottery toothbrush and toothpaste holders
