Anatomical Presentation Of The Brodmann Areas, Inferior View

Description

Brodmann area parcellation is mapped across the inferior (basal) surface of the human cerebrum, spanning the orbital frontal cortex anteriorly and the ventral temporal cortex posteriorly. Orbitofrontal regions along the gyrus rectus and orbital gyri occupy the anterior midline and anterolateral base, with labeled fields consistent with areas 10, 11, 12, and 47 arranged around the olfactory sulcus. Posterior to the temporal pole, the ventral temporal lobe shows the inferior temporal gyrus and occipitotemporal (fusiform) gyrus lateral to the parahippocampal gyrus and uncus, where you would expect to see allocations that correspond to areas 20, 21, 37, 38, 28, 34, 35, and 36 approaching the occipital underside. Basal cortical topography matters. Lesions along the orbitofrontal surface (for example, meningioma at the olfactory groove or traumatic contusion against the anterior cranial fossa) often produce disproportionate changes in executive control, social behavior, and olfaction, and a Brodmann map helps tie symptoms to cytoarchitectonic territory rather than gross gyri alone. On the ventromedial temporal side, the entorhinal and perirhinal regions (areas 28, 34, 35, 36) form a gateway to hippocampal circuitry and are early sites of Alzheimer pathology, while fusiform and inferior temporal territories (areas 37 and 20) are frequently discussed in reading networks and visual object recognition; the fixed inferior perspective keeps these basal landmarks contiguous, which is hard to appreciate in standard lateral views. Spatial relationships read quickly. Use this illustration for neuroanatomy and neuropsychology teaching when introducing cortical mapping, for atlas plates in neuroscience publishing, or for clinical education handouts that correlate basal-frontal and ventral-temporal lesions with deficits in olfaction, memory, and recognition.
