Understanding the Pupillary Light Reflex

This chapter explores the intricacies of the pupillary light reflex, emphasizing the roles of intrinsically photosensitive retinal ganglion cells and their pathways through the midbrain. It highlights the significance of bilateral responses and the interconnectedness of various visual processing nuclei, particularly the lateral geniculate nucleus and the superior colliculus. Additionally, the chapter examines the anatomical complexities of the oculomotor nerve and its implications for clinical conditions affecting pupillary function.
