Text-related functionality and dynamics of visual human pre-frontal activations revealed through neural network convergence.

ABSTRACT: Human prefrontal areas show enhanced activations when individuals are presented with images, under diverse task conditions. However, the functional role of these increased activations remains a deeply debated question. Here we addressed this question by comparing, dynamically, the relational structure of prefrontal activations and both visual and textual-trained deep neural networks (DNNs) during a visual memorization task. We analyzed intra-cranial recordings, conducted for clinical purposes, while patients viewed and memorized images of familiar faces and places. Our results reveal that relational structures in the frontal cortex elicited during visual memorization were predicted by text and not visual DNNs. Importantly, the temporal dynamics of these correlations showed striking differe
