The question is more how you define mind. And if we use the various definitions and concepts of consciousness and cognitive abilities, we do have a good idea where things located in the brain. In part from lesion studies (i.e. parts of the brain that have been damaged and resulting in cognitive changes), but also with animal models and other approaches (e.g. fMRI). These includes functions like memory, reasoning, recognition, emotions, and so on. We also know that these are dynamic processes, more related to activity than just localization. And due to the complexity we have not (afaik) a unified view how these components all work together. But even if I do not know how car works in detail, I can see that it does not work without a motor.
