Human Brain In Axial Section

Description

Cerebral hemispheres are presented in an axial (horizontal) section, with cortical gray matter forming a peripheral ribbon and central white matter occupying the deep centrum semiovale. Medial to the insular cortex, the basal ganglia and thalamus are visible as key subcortical gray matter masses, separated by the internal capsule as a dense white matter corridor running between the caudate nucleus and lentiform nucleus. Lateral ventricles lie near the midline structures, their CSF spaces contrasting with surrounding parenchyma and helping orient left to right anatomy in the fixed slice. Orientation is immediate. Axial brain sections are the daily language of CT and MRI, and this illustration supports direct crosswalk between gross neuroanatomy and imaging anatomy. The relationship of the putamen, globus pallidus, and thalamus to the internal capsule matters in hypertensive intracerebral hemorrhage and lacunar infarction, where a small lesion can interrupt corticospinal fibers and produce dense contralateral weakness. Even without vascular overlays, the lighting and material contrast between gray and white matter make the boundaries of deep nuclei legible, so the reader can localize pathology rather than memorizing isolated labels. Neuroanatomy faculty can place this illustration alongside axial MR examples when teaching subcortical organization, ventricular anatomy, and white matter pathways in medical and graduate neuroscience courses. Neurology and neuroradiology teams can also use it in patient education handouts to explain why basal ganglia or thalamic lesions often present with motor deficits, sensory syndromes, or capsular signs.
