Abstract
In this study we use Representational Similarity Analysis and naturalistic stimuli to investigate the role of narrative context in shaping context specific mnemonic representations. Functional MRI data was acquired while participants viewed the film Sliding Doors, featuring two altemating storylines with the same characters, who frequent the same locations, making it ideal for studying the emergence and organization of memory networks. We predicted a higher neural similarity effect within versus across context specific representations, with hippocampus as the main candidate region underlying this effect. We demonstrate that it is possible to distinguish storylines, as well as the characters populating them, based on their corresponding pattems of neural similarity in right fusiform gyrus and hippocampus.
