fusiform gyrus (FuG)

The term fusiform gyrus refers to one of six convolutions of the temporal lobe identified by dissection in the human, four of which are also found in the macaque. In order from the dorsolateral to ventromedial aspect of the hemisphere, the common convolutions are: superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus, and fusiform gyrus ( Crosby-1962 ); Martin-2000 ). Located on the ventral aspect of the cerebral hemisphere, the fusiform gyrus is separated from the inferior temporal gyrus laterally by the occipitotemporal sulcus. The collateral sulcus separates it from the parahippocampal gyrus of the limbic lobe anteromedially and from the lingual gyrus of the occipital lobe posteromedially. In the macaque the adjacent gyri are similar, but their boundaries are only partially defined by the sulci. In particular, the rostral boundaries with the parahippocampal gyrus and the inferior temporal gyrus are ill-defined. Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: T4, fusiform gyrus, Gyrus fusiformis, Gyrus occipito-temporalis lateralis, Gyrus occipitotemporalis lateralis, occipitotemporal gyrus, lateral occipitotemporal gyrus, lateral occipito-temporal gyrus, medial occipitotemporal gyrus-1 (Heimer)

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.
