The paper investigates whether hippocampal memory reactivation ensures overt recall, finding that alpha oscillations predict recall rather than reactivation alone.

This study compares electrical and ultrasound transcutaneous vagus nerve stimulation on associative memory, finding no improvement in recall accuracy but faster response times with electrical stimulation.

This study shows rhythmic light stimulation elicits multiple neural responses at different frequencies that separately affect perception, with implications for neuromodulatory techniques.

This study shows higher baseline alpha power is linked to faster visual search performance, challenging the idea that alpha oscillations reduce visual processing.

The paper shows that guided visual search enhances neuronal excitability to target features and reduces it to distractors in early visual cortex using MEG and RIFT.

This study shows that spindle-locked ripples in human NREM sleep are critical for memory reactivation, supporting their role in memory consolidation.

This study identifies electrophysiological signatures of veridical head direction in humans using EEG and intracranial recordings, revealing a posterior central signature and medial temporal lobe involvement.

This study shows that imperceptible 65Hz sensory stimulation enhances episodic memory recall by entraining endogenous 32.5Hz oscillations, while perceptible 32.5Hz and 43.3Hz stimulation do not have the same effect.

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.

This study uses MEG to show that phase separation of memories during hippocampal theta rhythms helps resolve mnemonic conflict by prioritizing relevant memories under high interference.

The paper shows that thalamocortical interactions predict human visual perception, with mediodorsal thalamic activity mediating prefrontal cortex contributions to perceptual performance.

This study investigates the roles of neocortical alpha/beta and hippocampal theta/gamma oscillations in episodic memory formation using MEG recordings during a sequence-learning task.

The paper shows that alpha/beta power decreases during encoding predict similar decreases during retrieval in episodic memory tasks.

The paper shows that decreases in alpha/beta power correlate with increased fidelity of stimulus-specific information in the brain across different cognitive tasks.

The paper analyzes human intracranial EEG data to show directional coupling between neocortical alpha/beta and hippocampal gamma oscillations during memory formation and retrieval.

This paper challenges bipolar referencing in intracranial EEG and proposes ICA as a more effective method for isolating local brain activity.
