Sponsored by the Brain Research Institute, University of California, Los Angeles, and the United States Air Force Office of Scientific Research This volume presents the proceedings of the Fourth Conference on Brain Function and Learning, hosted by UCLA's Brain Research Institute in collaboration with the U.S. Air Force Office of Scientific Research. The conference opened with a focus on neurochemical foundations of learning and memory, building on recent advances in biochemistry, such as the discovery of the genetic code. These discussions explored how biological memory operates at a molecular level, how it relates to the nervous system's flexibility, and the ways behavior adapts through biochemical processes. The conference featured presentations on the chemical changes underlying learning and how these changes manifest in brain function, setting the stage for further research in neurobiological and behavioral sciences. The latter half of the conference shifted toward electrophysiological and behavioral studies, offering insights into the brain's adaptive mechanisms during learning. Experts highlighted the role of mathematical models and the emerging field of artificial intelligence in simulating and understanding learning processes. This section underscored the importance of integrating theoretical and practical approaches to better understand how learning occurs both in biological systems and through computational models. Overall, this volume serves as a key resource for scientists interested in the dynamic interplay between brain function, learning, and memory. This title was originally published in 1963.
