One of the most interesting (and, in hindsight, "doh!") discoveries was that one of the main reasons researchers kept finding NO evidence of new neuron development in their test primates is because they kept them in an environment which shut that process down. In other words, it was the caged-living that stopped the neurogenesis process.
