Human Brain's Temporal Pole, Inferior View

Description

Temporal pole cortex forms the blunt anterior extremity of the temporal lobe and is seen here from an inferior (basal) perspective. Medially, the anterior parahippocampal gyrus and uncus curve toward the midline, with the rhinal and collateral sulci marking the transition to the ventral temporal surface. Laterally, the inferior temporal gyrus sweeps anteriorly toward the pole, while the fusiform (occipitotemporal) gyrus occupies the ventromedial aspect, separated by the occipitotemporal sulcus. Gyri and sulci are modeled with enough relief to appreciate how the pole rounds forward relative to the more posterior inferior temporal cortex. Temporal pole anatomy matters in epilepsy, neuro-oncology, and neurodegeneration because it sits at the anterior margin of the mesial temporal network that includes the amygdala and hippocampal head just posterior and superior to the uncus. Small lesions in this region can present with focal impaired awareness seizures, olfactory or gustatory auras, or semantic and social-emotional changes, and the basal view helps orient the surgeon or reader to the ventral landmarks used when describing an anterior temporal lobectomy or selective amygdalohippocampectomy corridors. Orientation is explicit. The inferior viewpoint clarifies the relationship of the uncus and parahippocampal gyrus to the temporal pole without the distraction of lateral opercular structures. Neuroanatomy instructors can drop this illustration into lectures on cerebral lobes and basal surface topography, and it also fits well in neurosurgical teaching files that explain seizure semiology localization or operative reports that reference the uncus, fusiform gyrus, and collateral sulcus. Medical publishers will find it useful for atlas plates and review articles discussing temporal pole involvement in temporal lobe epilepsy or frontotemporal dementia variants.
