In the recent decades, neuroscience research has diversified to encompass multiple subfields, each focusing on different levels of brain function at various spatial scales: from molecular processes, cellular ones, to local micro-circuits, to functions within a cortical region, and across regions, and even brain to brain interactions encompassing social behavior. But it is obvious that each of these processes does not act in isolation. Rather, the interactions between these levels allow for complex properties (such as perception, cognition and action) to emerge.
