Limbic system

Simplified medial or side view anatomical depiction of the human limbic system as a ring-like or C-shaped loop of interconnected deep and medial brain structures arching around the central brain, especially the thalamic or diencephalic region. Show a pale beige, tan, or pink-gray brain silhouette or surrounding brain tissue, with the limbic components highlighted as a distinct internal circuit in warm coordinated tones such as dark pink, muted pink, mauve, tan, orange, purple, and reddish-pink. The highlighted structures may include a curved hippocampus, almond-shaped amygdala, hypothalamus, mammillary bodies, septal area, and connecting fornix, rendered with smooth soft contours rather than detailed cortical folds. The overall appearance should emphasize the recognizable curved inner border or nested loop of the limbic circuit within the brain.
