This is a vintage, black and white scientific illustration depicting a cross-sectional view of a cerebellar convolution of a mammal. The image is a detailed diagram with a multitude of intricate lines and dots representing the cellular structure of the cerebellum. The diagram is divided into three sections labeled 'A', 'B', and 'C'. Within these sections, various cellular structures are illustrated, including neurons with branching fibers, and layers of cells. The neurons are depicted with complex dendritic trees and axons. The illustration is densely packed with these cellular elements, creating a textured and detailed representation of the cerebellar tissue. Numerous labels (a, b, c, d, e, h, i, j, m, n, o) are scattered throughout the diagram, pointing to specific cellular components or layers. The style is reminiscent of early 20th-century scientific illustrations, with a focus on detailed anatomical representation. Below the diagram, the text reads 'Coupe transversale demi-schématique d'une circonvolution cérébelleuse de mammifère', which translates to 'Semi-schematic transverse section of a cerebellar convolution of a mammal'.
