The<unk>  and<unk>  bulb lie in the<unk>  sulcus a sulcus formed by the medial orbital gyrus on the inferior surface of each frontal lobe. The<unk> s lie in the sulci which run closely parallel to the midline. Fibers of the<unk>  appear to end in the antero-lateral part of the<unk>  tubercle, the dorsal and external parts of the anterior<unk>  nucleus, the frontal and temporal parts of the prepyriform area, the cortico-medial group of amygdala nuclei and the nucleus of the stria terminalis. The<unk>  divides posteriorly into a medial and a lateral stria. Caudal to this is the<unk>  trigone, and the anterior perforated substance. Medial<unk>  stria The medial<unk>  stria turns medially behind the parolfactory area and ends in the subcallosal gyrus; in some cases a small intermediate stria is seen running backward to the anterior perforated substance. Lateral<unk>  stria The lateral<unk>  stria is directed across the lateral part of the anterior perforated substance and then bends abruptly medially toward the uncus of the parahippocampal gyrus.
