Basal view of the neural visual pathways. The temporal gyrus has been removed bilaterally, preserving the optic radiations (OptRad). The temporal stem has been removed, exposing the Meyer loop and the trajectory of its fibers that reach the inferior lip of the calcarine fissure (InfLipCaF). In the left temporal horn, the ependyma has been removed, and the tapetum can be seen along the atrium. (Image courtesy of E de Oliveira)
