Two very different approaches to identify functional connections between brain areas
Two recent studies have shown yet again that many more different parts of the brain are often involved in a given mental phenomenon than was once believed. In the brain, nothing is really isolated, and there are no “centres” of anything. Instead, we’re always dealing with multiple interconnected areas of the brain that form networks as demanded by the situations faced or the tasks to be performed. What’s most interesting about these two particular studies is that the researchers used two very different approaches to identify functional connections between brain areas: in one study, they visually traced the path of the axons projected by certain neurons, while in the other, they used genetic methods to isolate a new kind of membrane receptor.
