In a very interesting new finding, researchers have discovered the people’s brains contain individual neurons, or small groups of neurons, that seem exist only to recognize particular people or concepts. This would imply that there is one neuron, or at least a small group of neurons, in our brains for every unique thing that we know. However, that raises certain questions — for example, if this is true, then the brain should be a lot larger since there wouldn’t be room to represent everything a typical adult knows with unique neurons in that amount of space. On the other hand, perhaps the memories are not stored on the neuronal level at all, but instead are stored and computed on the sub-neuronal tubulin "quantum computing" level, which is the subject of much research these days. For more on that check out this book on research into quantum computing in the brain (found by: Josh).
