Reconstructing Spatio-Temporal Trajectories of Visual Object Memories in the Human Brain

This study uses EEG-fMRI fusion to show that visual object memory retrieval follows a backward spatio-temporal trajectory from conceptual to perceptual brain regions.

Theta rhythmicity governs the timing of behavioral and hippocampal responses in humans specifically during memory-dependent tasks

The paper shows that behavioral responses during memory tasks in humans exhibit rhythmicity tied to hippocampal theta oscillations, specifically for correctly remembered trials.

Feature-specific reaction times reveal a semanticisation of memories over time and with repeated remembering

The paper shows that repeated recall increases the semanticization of memories, as evidenced by longer perceptual-conceptual reaction time gaps over time.

Hippocampal-striatal functional connectivity supports processing of temporal expectations from associative memory

The paper investigates hippocampal-striatal functional connectivity during temporal expectation processing from associative memory, finding decreased hippocampal activity and increased putamen activity when expectations are violated.
