Abstract Although the distinction between episodic and semantic memory is supported by numerous neuropsychological studies, neuroimaging data have shown considerable overlap between regions that are activated during semantic and episodic remembering. This might indicate similar or shared mechanisms but might also result from inadequate task designs or poor functional magnetic resonance imaging signal coverage. Here we compared neural activations and representations associated with successful retrieval of episodic and semantic memories, using tasks that are more closely matched. A total of n = 40 participants recalled pairings between logos and brand names, where the pairings corresponded to real-world knowledge (semantic task) or were…

Abstract Successful navigation relies on the ability to process and encode detailed information about our dynamic environments. Beyond familiarity, emerging studies now highlight the crucial role of novelty detection in this process, the precise neural mechanism of which remains poorly understood. Using ultra-high field 7T fMRI, we investigated how the human brain encodes spatial novelty during virtual navigation, with a particular focus on graded representations that follow systematic transitions between novel and familiar spaces. Our results revealed novelty and familiarity specific neural responses within the posterior and anterior poles of the bilateral hippocampus, respectively. On the cortical surface, two separable…
