fovea
cochlea

Explanation:

The fovea is the part of the retina that has only cones. Cones are responsible for sharp, detailed, and color vision. The fovea is the center of focus for the clearest vision. The cochlea is part of the ear (related to hearing), gyri are folds in the brain, lobule can refer to a small lobe (e.g., in the liver or earlobe in a non - academic sense here), and fundus can refer to the base of an organ (like the fundus of the uterus or the ocular fundus which is a broader term for the back of the eye but not the specific cone - only area).

fovea
