1 Make a thorough inventory of any of the symptoms that I mentioned in the previous hypothyroidism blog to see if you might suffer from hypothyroidism.  Get the right thyroid tests including TSH, free T3, free T4, TPO, and anti-thyroglobulin antibodies.
The splenium is part of the corpus callosum, a structure of the brain that enables communication between the brain's two hemispheres. Its underside connects with a brain structure called the fornix, which a fibrous and arch-shaped formation of the brain.he brain's fourth ventricle is located in the back of the brain and connects to the spinal cord. The brain's corpus callosum holds the splenium. Each side of the brain is responsible for different tasks and modes of thought, and the corpus callosum, containing the spienium, allows communication between them.
Abstract. The splenium of the corpus callosum connects the posterior cortices with fibers varying in size from thin late-myelinating axons in the anterior part, predominantly connecting parietal and temporal areas, to thick early-myelinating fibers in the posterior part, linking primary and secondary visual areas.ccording to anatomical tracing studies, the fiber composition of the splenium is heterogeneous: its anterior part includes thin late-myelinating fibers from parietal and medial temporal association areas, while the posterior part contains thick early-myelinating fibers linking primary/secondary visual areas [ 1 â 5 ].
