Nucleus spherical

The spherical nucleus or oculoid nucleus (lat. corpus globosum nucleus, anatom.) is the shape of the superficial nucleus of the visual thalamus of the brain. It has the appearance of a smooth round formation of solid consistency with a diameter of 0.5-1.0 cm. The outer surface of the kernel is convex and matte. The inner surface is smooth, shiny, various shades of white or yellowish. Behind the central sulcus there is a slightly pronounced elevation. Laterally attached to the lower tangential zone and the posterolateral part of the leash zone.

The kernel substance has a soft consistency, the kernel is divided into lobes. It is adjacent to the posterior surface of the thalamus, optic chiasm and inferior colliculus. In the lower part, its surface comes into contact with the anterior gray commissure. The nucleus is located in the canal of the superior frontal gyrus; above, to the convex of the internal capsule, it passes into the anterior tubercle. The border of the posterior tubercle of the nucleus extends into the canal of the frontal sulcus, but the internal border of the nucleus is not precisely defined. The posterior tubercle is located at the junction of the medial and lateral surfaces of the optic radiation of the visual tract; the nuclei are a continuation of the middle thalamic region in the inferior frontal gyri. Its base has a convex shape, which emerges from the precentral lateral ventricle from below (inward from the subthalamic nucleus) and connects
