It seems like you might be referring to the "splenium of corpus callosum." The corpus callosum is a band of nerve fibers that connects the two hemispheres of the brain and facilitates communication between them. The corpus callosum is divided into four parts: 1. Rostrum 2. Genu 3. Body 4. Splenium The splenium is the thickest and most posterior part of the corpus callosum. It serves as a critical communication pathway by connecting the parietal and occipital lobes of the brain. These lobes play roles in critical processes such as visual perception, spatial awareness, and sensory integration. If you have any questions or are looking for specific advice, feel free to ask!
