One question that is crucial in cognitive neuroscience is how information and mental experiences are coded and represented in the brain. Scientists <answer>have gained much knowledge</answer> about the neuronal codes from the studies of plasticity, but most of such research has been focused on simple learning in simple neuronal circuits; it is considerably less clear about the neuronal changes involved in more complex examples of memory, particularly declarative memory that requires the storage of facts and events (Byrne 2007). Convergence-divergence zones might be the neural networks where memories are stored and retrieved.
Have researchers learned anything studying plasticity?
