The paper shows that aperiodic activity can mimic ripple power but not timing or spectral content, indicating human hippocampal ripples are distinguishable from aperiodic activity under realistic signal properties.

This study shows that targeting intracranial electrical stimulation to network regions defined by precision functional mapping evokes network-level effects in individual epilepsy patients.

The paper investigates visuospatial coding in the human hippocampus using intracranial EEG during a retinotopic mapping task, finding that slow theta oscillations scale with visual stimulus size and show contralateral bias.

The paper shows that hippocampal activity during scene encoding reflects the semantic content and temporal order of visual fixations, with first fixations on people being most significant for memory.

This study investigates how spatial and semantic memory are organized along the hippocampus's long axis using fMRI and eye tracking, finding a combination of gradient and modular dynamics.

The paper tests if targeting brain stimulation based on anatomical and functional network properties improves memory in patients.

This study shows that human hippocampal responses to stimulation vary with theta phase, indicating phase-dependent connectivity states.

The paper identifies cortical networks that reinstated semantic content and temporal context during episodic recall, showing how specialized systems organize memory retrieval.

The paper shows that the human hippocampus supports short-term memory processing during learning, influencing eye movements and cortical networks to guide effective spatiotemporal learning.

This study shows that stimulating the hippocampal network enhances the reinstatement of naturalistic event memories in humans, improving memory accuracy.

This study links hippocampal theta oscillations to memory-guided behaviors by analyzing eye movements and neural activity during a spatial memory task.

The paper examines how high-frequency gamma activity in epilepsy patients correlates with resting-state BOLD fluctuations, showing distinct hubness in memory encoding networks.

The paper shows that functional connectivity predicts changes in theta power from electrical stimulation, but only when stimulation occurs in or near white matter.
