Inferior optic radiations synapse in which region of the LGN?

Explanation:
Inferior optic radiations are the Meyer loop, which carry information from the superior visual field and travel through the temporal lobe to reach the primary visual cortex. The LGN is arranged retinotopically, with a lateral portion receiving input from the temporal retina (the part of the retina that aligns with fibers looping through the temporal lobe). Therefore, the signals that form the inferior radiations synapse in the lateral LGN. This fits the path of the Meyer loop and the way the LGN maps retinal input, unlike other regions that correspond to different retinal sectors.
