Descending occipital gyrus
Gyrus occipitalis descendens
- Eponym: Gyrus of Ecker
Definition
The descending occipital gyrus (of Ecker) is located posteriorly to the middle and inferior occipital gyri and appears as a thin cortical strip lying just anterior to the apex of the occipital pole.
The descending occipital gyrus is inconstant (9% in some studies) and appears when both the retrocalcarine and occipitopolar sulci are present.
