Art style: Cinematic Realistic.
Vertical 9:16. Hyper-realistic scientific visualization of a sleeping human brain inside the skull. The brain is shown during the final stage of sleep before waking. Neural activity gradually increases, with subtle waves of blue and warm golden electrical signals spreading through neural networks. Around the brain, a faint visualization of circadian rhythm signals and biological clock activity appears. Realistic anatomy, scientifically inspired visualization, cinematic volumetric lighting, extremely detailed neurons, shallow depth of field, Unreal Engine 5 quality, premium Netflix science documentary aesthetic.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
