Before revision:  Besides being powerful techniques for data analysis, ANNs provide a new approach for neuroscientists to build models that capture complex behaviors,  neural activity and  connectivity, as well as to explore optimization in neural systems  .
After revision:  Besides being powerful techniques for data analysis, ANNs provide a new approach for neuroscientists to build models that capture complex behaviors, neural activity and connectivity, as well as to explore optimization in neural systems , in ways that traditional models are not designed for .
