Cortical Representations of Visual Stimuli Shift Locations with Changes in Memory States.

ABSTRACT: Episodic memory retrieval is thought to rely on reactivation of the same content-sensitive neural activity patterns initially expressed during memory encoding.^1-6 Yet there are emerging examples of content representations expressed in different brain regions during encoding versus retrieval.^7-14 Although these differences have been observed by comparing encoding and retrieval tasks that differ in terms of perceptual experience and cognitive demands, there are many real-world contexts-e.g., meeting a new colleague who reminds you of an old acquaintance-where the memory system might be intrinsically biased either toward encoding (the new colleague) or retrieval (the old acquaintance).¹⁵¹⁶ Here, we test whether intrinsic memory states, independent o
