Since its publication in 1949, D.O. Hebb's, 'The Organization of Behavior' has been one of the most influential books in the fields of psychology and neuroscience. This edition provides a general framework for relating behavior to synaptic organization through the dynamics of neural networks.
I really liked this book. It took me forever to read, and was somewhat challenging in the beginning, but I now have a much fuller understanding of Hebbian theory, and its applications to emotion, attention, intelligence, and learning. Reading this, I was even more aware of how ahead of his time he really was. I'm really glad that I stuck it out!
