An ability to build structured mental maps of the world is central to human intelligence.
In rodents, the consolidation and extension of cognitive map representations is supported by sequential hippocampal place cell reactivations during rest, known as replay. These events occur in the context of transient high frequency ripple oscillations in the hippocampal local field potential, and default mode network (DMN) activation at the whole brain level. Recent developments in my lab now enable a precise measurement of neuronal representations in humans, including their fast sequential reactivation (neural replay). I will consider the role of replay in relation to human cognition, including how different types of replay support discrete function, as well as the implications of disorganized replay.
