Anatomical Diagram: A mid-sagittal illustration of the human brain, highlighting regions vulnerable to thiamine deficiency and Wernicke-Korsakoff Syndrome. The diagram depicts the frontal lobe with its characteristic gyri and sulci occupying the anterior and superior portions of the cerebrum. Key labeled structures in the central and posterior regions include the thalamus and hypothalamus, located superior to the small, rounded mamillary body. The brain stem is shown extending inferiorly, connecting to the spinal cord. Posterior to the brain stem is the cerebellum, illustrating its distinctive arbor vitae branching pattern. The lateral ventricle is represented as a blue, C-shaped structure above the thalamus. This illustration serves an educational purpose in neurology and nutrition, demonstrating the spatial relationships and functional anatomy of subcortical and brainstem structures often involved in metabolic encephalopathies.

This medical anatomical diagram provides a lateral view of the human brain, utilizing color-coding to delineate primary functional regions and lobes. The frontal lobe is highlighted in light blue at the most anterior position. Progressing posteriorly, the diagram identifies the motor cortex (purple) and the sensory cortex (yellow), which are separated by the central sulcus. The parietal lobe (yellow) follows posteriorly to the sensory cortex, while the occipital lobe is marked in pink at the most posterior pole. The temporal lobe is shaded in green, situated inferior to the frontal and parietal lobes. Below the occipital and temporal regions, the cerebellum is depicted with a distinct striated texture, contrasting with the gyri and sulci patterns of the cerebral cortex. The illustration is designed to teach regional brain anatomy and the spatial relationships essential for understanding corticomuscular coherence (CMC), movement planning, and tactile processing. The labels and color differentiation emphasize the distinct boundaries of these functionally specialized neural structures.

This anatomical diagram provides a lateral view of the human brain, specifically illustrating the cortical regions associated with the mirror neuron system. The line drawing highlights three key functional areas using shaded gray overlays and text labels: the premotor area in the frontal lobe, the primary motor cortex (M1) along the precentral gyrus, and the inferior parietal lobule in the parietal lobe. The diagram clearly depicts the complex surface anatomy of the cerebral cortex, including its gyri and sulci, which define the boundaries of these functional regions. The cerebellum is also visible inferiorly to the occipital and temporal lobes. This illustration is designed to teach the neuroanatomical basis of action-observation processing, demonstrating how the brain bridges visual perception of others' actions with its own motor representation. It is an educational resource suitable for neuroscience and clinical neurology, focusing on sensory-motor integration and the physiological mechanisms of social cognition.

This anatomical diagram provides a lateral view of the human brain, specifically the right cerebral hemisphere, illustrating the concept of neuro-functional reorganization. The background is a detailed medical illustration of the cerebrum, showing prominent gyri and sulci rendered in brownish-red tones. Superimposed on this anatomy are two 3D oval markers. A silver-white oval is positioned over the frontal lobe (specifically the prefrontal cortex area), and a light-blue oval is positioned over the parietal lobe (specifically the inferior parietal region). Two parallel horizontal arrows with circular endpoints connect these regions, pointing from the frontal marker to the parietal marker. This visual represents a 'network translation' or a posterior shift in brain activation patterns often observed during aging. The diagram illustrates how executive functions may shift from frontal resources to parietal regions to maintain cognitive performance as part of a compensatory mechanism in the aging brain. This educational graphic is relevant to neuroanatomy, geriatric psychology, and functional neuroimaging studies.

This medical anatomical diagram features a 3D surface-rendered model of the human brain, focusing on the cortical anatomy of the parietal lobe. The brain is presented in two panels: (A) a superior (top-down) view and (B) a lateral (side) view. The rendering utilizes a semi-transparent brown texture that highlights the gyri and sulci of the cerebral cortex. Specific anatomic regions associated with language and cross-modal processing are color-coded for educational identification. The supramarginal gyrus (SMG) is highlighted in opaque white, while the angular gyrus (AG) is highlighted in semi-transparent gray. In the lateral view (B), labels and indicator lines clearly demarcate these two adjacent regions, showing the SMG situated anteriorly to the AG within the inferior parietal lobule. This visualization is designed for neuroanatomical education, specifically to demonstrate the spatial relationship of parietal lobe structures involved in phonological processing and semantic integration, often studied via functional magnetic resonance imaging (fMRI) in clinical contexts like epilepsy or speech-language pathology.

Anatomical diagram of the medial aspect of the human brain, illustrating the major gyri and sulci labeled for neuroanatomical education. The diagram uses color-coding to differentiate cerebral lobes: frontal (blue), parietal (pink), and occipital/temporal (yellow/green). Key landmarks include the cingulate sulcus (cs) and its ascending branch (csab), which separate the superior frontal gyrus (sfg) and paracentral lobule (pcl) from the cingulate gyrus (acg, pcg). The central sulcus (ces) is visible superiorly. In the posterior region, the parieto-occipital sulcus (pos) separates the precuneus (pcun) from the cuneus (cun). The calcarine sulcus (calcs) is shown within the occipital lobe. Inferior structures depicted include the parahippocampal gyrus (phg), uncus (unc), collateral sulcus (cols), and the lateral occipitotemporal gyrus (lotg). This educational resource is designed for advanced neuroanatomy study, providing a standardized map of cortical folding and lobular divisions.

This anatomical diagram illustrates the superolateral surface of the human cerebral hemisphere, highlighting the primary gyri and sulci using a alphanumeric labeling system. The frontal lobe is categorized by gyri F1 (superior), F2 (middle), and F3 (inferior), with F3 further subdivided into orbital (a), triangular (b), and opercular (c) parts. The parietal lobe displays the superior (P1) and inferior (P2) parietal lobules. The temporal lobe contains the superior (T1), middle (T2), and inferior (T3) temporal gyri, while the occipital lobe shows the superior (O1), middle (O2), and inferior (O3) occipital gyri. Major landmark sulci are numbered, including the central sulcus (9), lateral sulcus (10), and parietooccipital sulcus (12). Secondary features such as the subcentral gyrus (d), transverse temporal gyri of Heschl (e, f), and the diagonal sulcus of Eberstaller (2) are also indicated. This schematic provides a foundational reference for neuroanatomical classification and functional localization within the human cerebral cortex.
