Donald O. Hebb

Donald O. Hebb was a Canadian psychologist best known for his groundbreaking work on how learning and memory work in the brain. He proposed that when two neurons (brain cells) are active at the same time, the connection between them becomes stronger. This idea, often summarized as "cells that fire together wire together," explains how experiences shape neural pathways, forming the basis for learning and memory. His theories have significantly influenced neuroscience and psychology, highlighting the importance of neural plasticity—the brain's ability to change and adapt through experience.
