Stimulus-response correlation analysis dissociates spatiotemporal cortical networks supporting speech production

The paper uses stimulus-response correlation analysis to identify dissociated cortical networks supporting stages of speech production, finding stable spatiotemporal signatures across individuals.

Distinct neural modes carry information about grasp force and phase in the sensorimotor cortex

The paper identifies distinct neural modes in the sensorimotor cortex that encode grasp force and timing during isometric grasps in tetraplegic individuals.

Biomimetic multi-channel microstimulation of somatosensory cortex conveys high resolution force feedback for bionic hands

This study evaluates biomimetic multi-channel microstimulation for restoring high-resolution force feedback in bionic hands through somatosensory cortex stimulation.

GABA Increases Sensory Transmission In Monkeys

This study shows that GABA facilitates sensory transmission in monkeys, increasing spinal and cortical neural responses to sensory inputs.

Microstimulation of human somatosensory cortex evokes task-dependent, spatially patterned responses in motor cortex

This study investigates how microstimulation of somatosensory cortex affects motor cortex activity in paralyzed individuals, finding task-dependent spatial patterns and showing that biomimetic stimulation improves control of a virtual hand.

Tessellation Of Artificial Touch Via Microstimulation Of Human Somatosensory Cortex

The paper investigates the localization of intracortical microstimulation-evoked sensations in human somatosensory cortex and demonstrates improved localization with multi-channel stimulation in a bionic hand.

Cortical ripples during NREM sleep and waking in humans

This study shows cortical ripples occur during human NREM sleep and waking with similar characteristics to hippocampal ripples, associated with upstates, spindles, and unit co-firing, suggesting a role in memory consolidation.

Inter-Individual Variability in Dorsal Stream Dynamics During Word Production

The paper examines inter-individual variability in dorsal stream activation during word production using intracerebral recordings from epileptic patients.

Internal states as a source of subject-dependent movement variability and their representation by large-scale networks

The paper identifies two internal states that influence movement variability and shows they are encoded by large-scale brain networks in humans.

A New Paradigm for Investigating Real-World Social Behavior and its Neural Underpinnings

The paper describes an immersive paradigm for studying natural social behavior and its neural correlates in epilepsy patients using synchronized behavioral and neurophysiological data.

Widespread ripples synchronize human cortical activity during sleep, waking, and memory recall

This paper shows that high-frequency ripples synchronize cortical activity across distant brain regions during sleep, waking, and memory recall, supporting the binding-by-synchrony theory.

A Hybrid High-Resolution Anatomical MRI Atlas with Sub-parcellation of Cortical Gyri using Resting fMRI

The paper presents a high-resolution MRI atlas with two parcellation schemes, using structural and functional data to improve cortical sub-parcellation.

Human spindle variability

The paper shows that sleep spindles vary continuously across multiple dimensions rather than being strictly divided into slow and fast categories.

Neural Fragility as an EEG Marker of the Seizure Onset Zone

The paper introduces and validates neural fragility as an EEG biomarker for identifying the seizure onset zone, showing higher prediction accuracy than clinician judgment.

Improved identification and differentiation from epileptiform activity of human hippocampal sharpwave-ripples during NREM sleep

This study identifies and differentiates human hippocampal sharpwave-ripples (HC-SWR) from epileptiform activity during NREM sleep, showing similar characteristics to rodents but with lower frequency.

Coordination of human hippocampal sharpwave-ripples during NREM sleep with cortical theta bursts, spindles, downstates and upstates

This study shows that human hippocampal sharpwave-ripples (HC-SWR) are correlated with various cortical sleep waves during NREM sleep, with specific spatial and temporal preferences.

Using Network Analysis to Localize the Epileptogenic Zone from Invasive EEG Recordings in Intractable Focal Epilepsy

The paper develops a network analysis algorithm to localize the epileptogenic zone using invasive EEG recordings, showing better agreement with clinical outcomes in successful surgeries.
