The Organization of Behavior by D.O. Hebb is a groundbreaking work in neuroscience and psychology that introduces the concept of Hebbian learning, famously summarized as "neurons that fire together, wire together." Hebb explores how neural connections strengthen through repeated activation, forming the basis of learning, memory, and behavior. He bridges the gap between biological processes and cognitive functions, proposing that psychological phenomena arise from neural activity patterns. His work laid the foundation for modern theories of neuroplasticity and artificial neural networks. This book remains a cornerstone in cognitive science, influencing research in psychology, neuroscience, and artificial intelligence.
