Study 1. Semantic vs Episodic memories

We aim to examine to which extent top-down predictions in early visual cortex (EVC) can be related to episodic and semantic memory. In order to do so, we will use a visual occluder and fMRI to measure brain activity on a region of EVC which receives no external stimulation, while the rest of the visual field contains external information that can trigger memory retrieval. Our main goal is to find differential activity patterns within V1 and V2 in the occluded region (Smith and Muckli, 2010) that can be attributed to feedback information based on episodic and semantic memory from the hippocampus and ventromedial prefrontal cortex (vmPFC), respectively.
