Tests looked at which parts of the brain reacted to stimuli for how long, and whether there was a simultaneous reaction throughout the whole brain. What did those tests find? So, there was somewhat mixed. Is it two to one for IT versus TMW? It's more complicated than that because this is just the first evaluation of the first experiment. There's a second experiment, plus there are more experiments being carried out in animals. And so, this has to unfold over the next years.
