There is a separation, called the sulcus limitans, and lateral to this are the sensory nuclei.

Lateral to the sulcus limitans is the area of the vestibular system, which is involved in special sensation.

The sulcus limitans can also be located by searching laterally from the medial eminence.

The alar plate and the basal plate are separated by the sulcus limitans.

Above the superior fovea sulcus limitans presents a flattened grey area called "locus ceruleus".

In the developing nervous system, the basal plate is the region of the neural tube ventral to the sulcus limitans.

Near the sulcus limitans are the visceral afferent nuclei, namely the solitary tract nucleus.

During the maturation of the neural tube, its lateral walls thicken and form a longtitudinal groove called the sulcus limitans.

This nucleus is located beneath the fourth ventricle in the caudal portion of the pons, medial to the sulcus limitans.

Lateral to all these bumps previously discussed is an indented line, or sulcus that runs rostrally, and is known as the sulcus limitans.

On either side of this sulcus is an elevation, the medial eminence, bounded laterally by a sulcus, the sulcus limitans.

In the floor of the fourth ventricle, the sulcus limitans separates the cranial nerve motor nuclei (medial) from the sensory nuclei (lateral).
