In neuroanatomy, the paracentral lobule is on the medial surface of the cerebral hemisphere and is the continuation of the precentral and postcentral gyri.The paracentral lobule controls motor and sensory innervations of the contralateral lower extremity.

The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.

Schematic diagram of the human eye. It shows a horizontal section through the right eye. The eye is made up of three coats, or layers, enclosing various anatomical structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera, which provide shape to the eye and support the deeper structures.

Medial eye fields are areas in the frontal lobe of the primate brain that play a role in visually guided eye movement. [1] Most neuroscientists refer to this area as the supplementary eye fields . Eye fields are divided into two hemispheres regulated by s onic hedgehog ( Shh ) and Six3 .
