fusiform gyrus
Acronym:
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: lateral occipitotemporal gyrus, lateral occipito-temporal gyrus, occipitotemporal gyrus, T4, Gyrus fusiformis, Gyrus occipitotemporalis lateralisNeuroNames ID : 139
