What does the splenium of the corpus callosum connect?

The splenium of the corpus callosum connects the occipital lobes of both the left and right hemispheres. This structure is located at the posterior part of the corpus callosum and serves as a crucial pathway for communication between the two hemispheres, specifically facilitating visual and spatial information exchange that is processed in the occipital lobes. This connection is vital for integrating visual input and ensuring coherent visual perception across both sides of the visual field. Given its specific role in linking the occipital areas, the choice referencing the occipital parts directly identifies the correct function of the splenium within the broader context of interhemispheric communication.
