Plr pathway
Webb28 sep. 2024 · PLR is mediated from the retina through the optic nerve, opt, pretectal nucleus, and oculomotor nerve to the pupillae muscle (Fig. 1). Because LAG intake improved PLR in the model, it should protect axons involved in the PLR pathways. Therefore, injury reduction in the opt by LAG intake should help improve the PLR. Webb13 apr. 2024 · Bromate formation is a complex process that depends on the properties of water and the ozone used. Due to fluctuations in quality, surface waters require major adjustments to the treatment process. In this work, we investigated how the time of year, ozone dose and duration, and ammonium affect bromides, bromates, absorbance at 254 …

The OPN is a midbrain nucleus, the shell of which plays a central role in PLR pathway. Neurons in the OPN shell project to the Edinger–Westphal nucleus which in turn sends projections to the ciliary ganglion.
