Discovery of the Neuron Doctrine

Santiago Ramón y Cajal's meticulous late-19th-century drawings established that the nervous system comprises discrete individual cells—neurons—connected by synapses, overturning the prevailing reticular theory. This cellular foundation outperforms Neuroplasticity by providing the immutable unit for all neural communication, and it remains cited in over 15,000 contemporary studies each year, underscoring its enduring impact.
