Human hippocampal ripples tune cortical responses in uncertain visual contexts

The paper shows that hippocampal ripples predict visual stimulus unpredictability and modulate cortical responses in humans.

Successful working memory linked to theta connectivity patterns in the hippocampal-entorhinal circuit

The paper uses machine learning and intracranial EEG to show that theta-band connectivity between hippocampus and entorhinal cortex supports working memory maintenance through specific directional patterns.

Information flows from hippocampus to cortex during replay of verbal working memory items.

The paper examines information flow between auditory cortex and hippocampus during verbal working memory tasks, finding a reversal of direction during memory maintenance.

Neuronal firing in the medial temporal lobe reflects human working memory workload, performance and capacity.

This study shows that neuronal activity in the medial temporal lobe reflects working memory workload, performance, and capacity in humans during a visual working memory task.

Functional synchronization between hippocampal sEEG, parietal ECoG and scalp EEG during a verbal working memory task.

The paper analyzes synchronization between hippocampal sEEG, parietal ECoG, and scalp EEG during a verbal working memory task, finding increased functional coupling during memory maintenance.
