Here, we present a standardized series of protocols to observe the superior ocular sulcus, a recently-identified, evolutionarily-conserved structure in the vertebrate eye. Using zebrafish larvae, we demonstrate techniques necessary to identify factors that contribute to the formation and closure of the superior ocular sulcus.

The present work provides a comprehensive set of guidelines for manually tracing the medial temporal lobe (MTL) structures. This protocol can be applied to research involving structural and/or combined structural-functional magnetic resonance imaging (MRI) investigations of the MTL, in both healthy and clinical groups.
FAQs
Cortical folding increases the cerebral cortex’s surface area without requiring a proportionate expansion of the brain’s overall dimensions. In this arrangement, the parieto-occipital sulcus helps organize neighboring gyri and separates cortical territories that belong to the parietal and occipital lobes. This folding pattern therefore links brain shape with the spatial arrangement of nearby functional regions.
Its position on the medial surface provides a consistent anatomical reference for relating nearby tissue to the visual and parietal cortices. Because it marks the transition between the parietal and occipital lobes, researchers can use it to orient anatomical observations and interpret the location of cortical regions involved in visual-spatial organization.
The sulcus illustrates how anatomical boundaries can support the study of functional organization. Its location helps researchers examine how neighboring parietal and occipital regions are arranged in relation to visual-spatial processing. It does not by itself describe every function of those regions, but it supplies a structural landmark for investigating how cortical form corresponds with functional areas.
Researchers examine the medial surface of a cerebral hemisphere and locate the prominent groove separating the parietal and occipital lobes. They can then use its position to orient surrounding gyri and identify nearby visual and parietal cortical areas. This landmark-based approach supports systematic examination of brain organization in anatomical specimens.
In neuroimaging, the sulcus serves as an anatomical landmark for locating and comparing nearby cortical regions. Its relationship to the parietal and occipital lobes helps researchers interpret the position of visual and parietal areas in images. This makes it useful when studying cortical organization, visual-spatial processing, or structural differences across examined brains.
Because the parieto-occipital sulcus has a recognizable position, researchers can use it to describe the location of structural changes or lesions relative to neighboring lobes and cortical regions. Such localization is relevant to clinical neuroscience, where distinguishing whether an abnormality lies near visual or parietal tissue can support the study of its anatomical context.
The parieto-occipital sulcus is relevant because sulci arise as part of cortical folding, a developmental process that shapes surface area and organizes gyri. Examining this landmark allows researchers to consider how the medial cerebral cortex becomes spatially arranged and how developmental patterns relate to the later identification of visual, parietal, and visual-spatial regions.
