> Historically no test existed other than behavior observations. That's not too different from what I read this test as doing, except that it's observing neural activity while observing behaviors. Naturally, neural activity during behaviors is strongly correlated with features of the behaviors themselves, so it's quite possible that this is just another way of operationalizing/coding the behavior-based diagnosis approach. That could have advantages (maybe it's more repeatable, for example), but they don't appear to be claiming that they're doing something radically different, like identifying causal neural features.
