Camillo Golgi's image of a dog’s olfactory bulb from his Sulla fina anatomia degli organi centrali del sistema nervoso, 1885. A detailed anatomical illustration on aged cream paper showing layered neural structures of a dog's olfactory bulb. Large, bold black neurons dominate the middle sections, their sprawling dendrites branching upward like bare winter trees. At the top, shaded gray dome-shaped glomeruli are populated with star-shaped red neurons whose processes weave through flowing parallel fiber bundles. Slender blue threadlike fibers run vertically throughout, contrasting with the heavy black axons. At the bottom, finer and more delicate cells scatter into an increasingly sparse network of thin black lines. The overall composition has a striking visual rhythm, moving from dense complexity at the top to open, airy tracery at the bottom, with letters (a, b, d) annotating specific structures throughout. https://commons.wikimedia.org/wiki/Category:Camillo_Golgi#/media/File:Camillo_Golgi's_image_of_a_dog%E2%80%99s_olfactory_bulb_(detail_2).jpg
