Default mode network and emotion concepts
Appendix D endnote 16, from Lisa Feldman Barrett.
Some context is:
Other studies make a similar case for emotion perception.
A number of studies now provide evidence that the default mode network is important for representing multimodal summaries of emotion concepts. In one example, test subjects viewed moving faces and posed body postures (with faces obscured), and listened to vocalizations portraying anger, disgust, fear, happiness, and sadness. The scientists observed that neural activity overlapped in key nodes of the default mode network. This experiment did not use many facial configurations or many trials, so it was probably not as powerful as it needed to be. As a consequence, only the strongest activations were visible (the rest being buried in measurement noise), revealing only the main hubs of the network rather than the network in its entirety. But it still provided reliable results, giving us confidence that the default mode network represents efficient, multisensory summaries of an emotion concept.
We now also have evidence that the patterns of neural activity while constructing emotional experiences are similar to those when constructing emotion perceptions, particularly in… can you guess? The default mode network.
