Convolutional neural networks reveal topic-level representations of sentences in medial prefrontal cortex, lateral anterior temporal lobe, precuneus, and angular gyrus

Abstract: When reading a sentence, individual words can be combined to create more complex meaning. In this study, we sought to uncover brain regions that reflect the representation of meaning at the sentence level, as opposed to only the meaning of their individual constituent words. Using fMRI, we recorded the neural activity of participants while reading sentences. We constructed sentence topic-level representations using the final layer of a convolutional neural network (CNN) trained to classify Wikipedia sentences … Show more
