Ramón y Cajal's Neuron Doctrine

Ramón y Cajal's Neuron Doctrine states that the brain is made up of individual cells called neurons, which are the basic units of neural communication. Each neuron is a separate, specialized cell that connects to others through small contact points called synapses, rather than merging into a continuous network. This discovery revolutionized our understanding of the brain by showing that information transmission occurs through specific connections, enabling complex processes like thought, memory, and movement. Essentially, the Neuron Doctrine highlights that the brain's structure is organized into discrete units that work together via connections, much like an intricate network of communication lines.
