Trancred 2005 The Superior Temporal Gyrus contains the auditory (primary and association) areas of the cortex, which are involved in the interpretation of sounds. Structures: Collateral Sulcus Corpus Callosum Hippocampal Gyrus Inferior Temporal Gyrus Inferior Temporal Sulcus Lateral Fissure Lateral Ventricle Middle Temporal Gyrus Occipitotemporal Gyrus Parahippocampal Gyrus Parieto-occipital Sulcus Primary Auditory Area Primary Olfactory Area Superior Temporal Gyrus Superior Temporal Sulcus Transverse Temporal Gyrus Uncus Information: Boundaries: On the lateral surface the temporal lobe is bounded posteriorly by the imaginary line extending downwards from the parieto-occipital sulcus to the preoccipital notch. It is bounded superiorly by the lateral fissure and a horizontal line extending from the lateral fissure to meet the imaginary line just described. On the medial surface it is bounded posteriorly by a line extending from the splenium of the corpus callosum to the preoccipital notch. Gyri and Sulci: The lateral surface of the temporal lobe is formed by the superior, middle and inferior temporal gyri, which are separated from each other by the superior and inferior temporal sulci. The superior surface of the superior temporal gyrus, which forms the floor of the lateral fissure, is thrown into several transversely oriented folds, which are called the transverse temporal gyri (of Heschl). The inferomedial surface of the temporal lobe is formed by (from medial to lateral) the parahippocampal gyrus, the occipitotemporal gyrus and the inferior temporal gyrus. The occipitotemporal gyrus is separated from the parahippocampal gyrus by the collateral sulcus and from the inferior temporal gyrus by the occipitotemporal sulcus. The rostral part of the parahippocampal gyrus hooks backward to form a bump on its medial surface called the uncus. Above the parahippocampal gyrus (not visible from the inferior surface) is the hippocampal gyrus, which actually forms the medial wall of the inferior (temporal) horn of the lateral ventricle. Specific Functional Areas: (1) Primary Auditory Area - located on the transverse temporal gyri. (2) Primary Olfactory Area - located on the uncus. |
