A new study by MIT researchers that documents neural activity in the brains of dreaming rats shows that the purpose of dreaming is learning.
Brain researchers have long assumed that immediate memories are laid down in the hippocampus and later transferred to the neocortex for long-term storage. Dr. Wilson said the process was not just a transfer of memory, however, but more probably a sophisticated processing of data in which the neocortex learned selective information from the hippocampus.
“The neocortex is essentially asking the hippocampus to replay events that contain a certain image, place or sound,” he said. “The neocortex is trying to make sense of what is going on in the hippocampus and to build models of the world, to understand how and why things happen.”
Well, I dream a lot, and my dreams tend to be rather vivid. I've observed that they usually do contain bits and pieces of what I've experienced or thought about that day, but in bewildering disorder.
