Shade/hatch the VENTRAL lesion zone covering cerebral peduncle and CN III fascicle on the LEFT side. Bold title: WEBER SYNDROME. Two annotation boxes: left side "Ipsilateral CN III Palsy: ptosis, mydriasis, down-and-out eye", right side "Contralateral Hemiplegia (face + limb)". Simple clean educational diagram.

Hand-drawn pencil sketch of midbrain transverse cross-section for Benedikt Syndrome. Medical textbook illustration style, black ink on white. Show oval midbrain shape with: superior colliculus bumps on top, cerebral peduncles at bottom, aqueduct small circle at top center. Label structures: Cerebral Peduncle, CN III Fascicle, Red Nucleus, Substantia Nigra, Brachium Conjunctivum, Aqueduct, Tegmentum. Shade/hatch the TEGMENTAL lesion zone covering Red Nucleus and CN III fascicle on LEFT side, but sparing the cerebral peduncle. Bold title: BENEDIKT SYNDROME. Two annotation boxes: "Ipsilateral CN III Palsy (dilated pupil)", "Contralateral Hemitremor / Hemichorea / Hemiathetosis (Red Nucleus)". Simple clean educational diagram.

Hand-drawn pencil sketch of midbrain transverse cross-section for Claude Syndrome. Medical textbook illustration style, black ink on white. Show oval midbrain shape with: superior colliculus bumps on top, cerebral peduncles at bottom, aqueduct small circle at top center. Label structures: Cerebral Peduncle, CN III Fascicle, Red Nucleus, Brachium Conjunctivum, Superior Cerebellar Peduncle, Aqueduct, Dorsal Tegmentum. Shade/hatch the DORSAL TEGMENTAL lesion zone covering Brachium Conjunctivum, dorsal Red Nucleus and CN III fascicle on LEFT side. Bold title: CLAUDE SYNDROME. Two annotation boxes: "Ipsilateral CN III Palsy", "Contralateral Cerebellar Ataxia: dysmetria, asynergia (Brachium Conjunctivum)". Simple clean educational diagram.

Hand-drawn medical sketch of midbrain cross-section showing Weber Syndrome. Black ink pencil style on white background. Draw an oval midbrain cross-section with these labeled parts: small circle at top center labeled "Aqueduct", two bumps at top labeled "Superior Colliculus", two large rounded lobes at bottom labeled "Cerebral Peduncle (Crus Cerebri)", central round structure labeled "Red Nucleus", darker band below red nucleus labeled "Substantia Nigra", small dots exiting ventromedially labeled "CN III Fascicle". On the LEFT side, draw a large dark shaded irregular patch covering the LEFT cerebral peduncle and LEFT CN III fascicle - label this shaded zone with an arrow saying "LESION SITE". Title at top in bold: "WEBER SYNDROME". Bottom annotations: arrow to CN III fascicle "Ipsilateral CN III Palsy", arrow to cerebral peduncle "Contralateral Hemiplegia". Keep it simple, clean, educational.
