Communities of researchers, scholars, or professionals engage in sustained discourse with new insights and discoveries occurring over time as a result of varied perspectives and interpretations.
"Scientists normally test a theory by running experiments to see if the predictions made by the theory hold up or not. But neuroscience is unusual. There are hundreds to thousands of published papers in every subfield, and most of these papers present experimental data that are unassimilated into any overall theory. This provides theorists like myself an opportunity to quickly test a new hypothesis by searching the past research to find experimental evidence that supports or invalidates it."
