Ramón y Cajal's neuronal doctrine

Ramón y Cajal’s neuronal doctrine established that the brain is made up of individual nerve cells called neurons, rather than a continuous network. He showed that neurons are separate cells that communicate via small gaps called synapses. This discovery revolutionized neuroscience by clarifying how information travels in the brain, emphasizing that each neuron is a distinct unit with its own structure and function. His work laid the foundation for understanding neural communication, learning, and brain organization, significantly advancing our knowledge of the nervous system’s cellular nature.
