Cajal's Drawings

Cajal's drawings are detailed illustrations of neurons, the brain's fundamental cells, created by the neuroscientist Santiago Ramón Cajal. Using advanced microscopy, he observed the intricate structure of nerve cells, including their cell bodies, dendrites, and axons. His precise illustrations revealed how neurons connect through tiny gaps called synapses, laying the foundation for understanding how the brain processes information and controls the body. These drawings transformed neuroscience by visually demonstrating the complexity and organization of the nervous system, and they remain influential in illustrating neural architecture and connectivity today.
