THE LONG DARK CODES MOVIE

Outside of the visual areas however, there was not a lot of decoding. The results showed that the identity of visually familiar and personally familiar faces was decoded with accuracy across the brain in areas that are mostly involved in visual processing of faces. This allowed the researchers to use machine learning classifiers to predict what stimuli a participant was looking at based on the brain activity of the other participants.

The movie data, which is publicly available, was used to apply hyperalignment and align participants' brain responses into a common representational space. In the third task, participants watched parts of The Grand Budapest Hotel.

In two of the tasks, participants were presented with images of four other personally familiar graduate students and four other visually familiar persons, who were previously unknown.

The team used data obtained from three fMRI tasks with 14 graduate students who had known each other for at least two years.

'The surprising part of our findings was that the shared information about personally familiar faces also extends to areas that are non-visual and important for social processing, suggesting that there is shared social information across brains.'ДЇor the study, the research team applied a method called hyperalignment, which creates a common representational space for understanding how brain activity is similar between participants. 'Within visual processing areas, we found that information about personally familiar and visually familiar faces is shared across the brains of people who have the same friends and acquaintances,' says first author Matteo Visconti di Oleggio Castello, Guarini '18, who conducted this research as a graduate student in psychological and brain sciences at Dartmouth and is now a neuroscience post-doctoral scholar at the University of California, Berkeley.
