splenium

Another area, the splenium, was found to be larger in women in some studies.

They found that the larger the splenium in the women, the better they were on tests of verbal fluency.

Both the splenium and the isthmus are located toward the rear of the corpus callosum.

The genu, body, and splenium were identified to confirm complete development of the corpus callosum.

After perfusion the brains were visually inspected to determine whether or not the splenium was fully developed.

The part between the body and the splenium is often markedly thinned and thus referred to as the "isthmus".

However, the splenium and the isthmus subregions of the corpus callosum are larger in females.

In 1982 a different area of the corpus callosum, the splenium, was reported by researchers to be larger in women than in men.

Near the splenium the fimbria separates from the hippocampus as the crus fornicis.

Alexia without agraphia (seen with damage to splenium of corpus callosum)

Alexia without agraphia results from a left occipital splenium of the corpus callosum lesion.

This difference is evident in the anterior and posterior regions of the corpus callosum but not in the splenium.

Reduced anisotropy levels of white matter integrity and decreased anisotropy in the splenium of the corpus callosum.

Left and right angular gyri are connected by the dorsal splenium and isthmus of the corpus collosum.

Further evidence of laterality disruption was manifested by incomplete splenium development in 8 of the 10 EtOH-exposed rats.

Although the callosotomy was reported to be complete, follow-up MRI in 1984 revealed spared fibers in the rostrum and splenium.

The body of lateral ventricle (cella) extends from the interventricular foramen to the splenium of the corpus callosum.

The in utero effect of EtOH on splenium development has also been observed in humans with FAS.

Posterior cingulate gyrus is connected with retrosplenial cortex and this connection is part of the dorsal splenium of the corpus callosum.

"The size of the splenium," Dr. Hines said, "may provide an anatomical basis for increased communication between the hemispheres, and perhaps as a consequence, increased language abilities."

Its caudal and splenium portions contain fibres that originate from the primary and second auditory cortices, and from other auditory responsive areas.

These include hypoplastic corpus callosum with a missing rostrum and posterior part of the splenium with bulbous caudate nuclei bulging towards the frontal horns.

A sagittal section of the splenium shows that the posterior end of the corpus callosum is acutely bent forward, the upper and lower parts being applied to each other.

Sowell et al. [ 22 ] , using MRI analytic methods determined that EtOH-related callosal area reductions were most severe in the splenium.

Pure alexia almost always involves an infarct to the left posterior cerebral artery (which perfuses the splenium of the corpus callosum and left visual cortex, among other things).
