rhinal sulcus - BrainInfo

rhinal sulcus (rhs)

The term rhinal sulcus refers to a groove in the cerebral cortex of the human ( Carpenter-1983 ), macaque ( Martin-2000 ), rat ( Swanson-2004 ) and mouse ( Hof-2000 ). Defined topologically by dissection it is located in the human ( Economo-1927 ) and macaque ( Martin-2000 ) on the ventromedial surface of cerebral cortex where it separates the anterior parahippocampal gyrus of the limbic lobe from the inferior temporal gyrus of the temporal lobe. Some authors regard it to be an extension of the collateral sulcus in the human ( Mai-2004 ). One of only four grooves in the cerebral cortex of the rat ( Swanson-2004 ), it runs longitudinally on the ventrolateral surface, almost the entire length of the cerebral cortex. Rostrally it is more than a groove; it totally separates the olfactory system ventrally from the lateral orbital area dorsally. Progressing caudally, the dorsal and ventral structures join, it becomes a shallow groove separating the olfactory system from the medial orbital area dorsally. Further caudally it shortly disappears from the medial surface of the hemisphere, but continues separating the olactory areas from the lateral orbital area and agranular insular area on the lateral surface of the hemisphere. runs as a groove within that areathe entorhinal cortex ventrally from the ectorhinal area dorsally. More rostrally, the perirhinal area intervenes between those two areas, and the rhinal sulcus runs within it. At about the anterior-posterior level of the hypothalamus, the ectorhinal area disappears and the sulcus separates the entorhinal cortex and the perirhinal area ventrally from the agranular insula dorsally. Rostrally from there, it runs within the agranular insular area and most rostrally it separates the piriform cortex ventrally from the agranular insular area dorsally ( Swanson-2004 ). A similar but less prominent, interrupted sulcus is found in the mouse ( Hof-2000 ).

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
