Cajal's Theories of Neuron Structure

Santiago Ramón y Cajal, a pioneering neuroscientist, proposed that neurons are individual cells that communicate with each other through specialized connections called synapses. He suggested that the brain is made up of a vast network of these interconnected neurons, each with distinct structures: the cell body, dendrites that receive signals, and axons that transmit impulses. Cajal's theories laid the foundation for our understanding of how neural networks function and emphasized the importance of individual neurons in processing information in the brain, which is crucial for learning, memory, and behavior.
