This visually evocative short film pays tribute to the Spanish neuroanatomist Santiago Ramón y Cajal through a cinematic journey into his intricate drawings of the retina. Blending archival illustrations with contemporary microscopy and animation, the film explores the beauty of neuronal architecture and the visionary mind that laid the foundation for modern neuroscience. In a contemplative narrative, it contrasts the intimate precision of Cajal’s sketches with the dynamic pulsations of living tissue, embodying the convergence of art and science.
