Spatiotemporally distributed frontotemporal networks for sentence reading Open
Reading a sentence entails integrating the meanings of individual words to infer more complex, higher-order meaning. This highly rapid and complex human behavior is known to engage the inferior frontal gyrus (IFG) and middle temporal gyrus…

Studying memory processes at different levels with simultaneous depth and surface EEG recordings Open
Investigating cognitive brain functions using non-invasive electrophysiology can be challenging due to the particularities of the task-related EEG activity, the depth of the activated brain areas, and the extent of the networks involved. S…

Critical role of the ventral temporal lobe in naming Open
Objective Lexical retrieval deficits are characteristic of a variety of different neurological disorders. However, the exact substrates responsible for this are not known. We studied a large cohort of patients undergoing surgery in the dom…

A comparison of uni- and multi-variate methods for identifying brain networks activated by cognitive tasks using intracranial EEG Open
Cognitive tasks are commonly used to identify brain networks involved in the underlying cognitive process. However, inferring the brain networks from intracranial EEG data presents several challenges related to the sparse spatial sampling …

The spatiotemporal dynamics of semantic integration in the human brain Open
Language depends critically on the integration of lexical information to derive semantic concepts. The neurobiology of this fundamental aspect of human cognition remains mostly unknown. Limitations of spatiotemporal resolution have previou…

A Spatiotemporal Map of Reading Aloud Open
Reading words aloud is a fundamental aspect of literacy. The rapid rate at which multiple distributed neural substrates are engaged in this process can only be probed via techniques with high spatiotemporal resolution. We probed this with …

Imaging the effective networks associated with cortical function through intracranial high‐frequency stimulation Open
Direct electrical stimulation (DES) is considered to be the gold standard for mapping cortical function. A careful mapping of the eloquent cortex is key to successful resective or ablative surgeries, with a minimal postoperative deficit, f…

The critical role of the ventral temporal lobe in word retrieval Open
Deficits in word retrieval are a hallmark of a variety of neurological illnesses spanning from dementia to traumatic injuries. The role of the dominant temporal lobe in fluent naming has been characterized by lesional analyses, functional …

Cingulate cortex function and multi-modal connectivity mapped using intracranial stimulation Open
The cingulate cortex is part of the limbic system. Its function and connectivity are organized in a rostro-caudal and ventral-dorsal manner which was addressed by various other studies using rather coarse cortical parcellations. In this st…

Unsupervised Detection of High-Frequency Oscillations Using Time-Frequency Maps and Computer Vision Open
High-frequency oscillations >80 Hz (HFOs) have unique features distinguishing them from spikes and artifactual components that can be well-evidenced in the time-frequency representations. We introduce an unsupervised HFO detector that uses…

Spatiotemporal Dynamics of Orthographic and Lexical Processing in the Ventral Visual Pathway Open
Reading is a rapid, distributed process that engages multiple components of the ventral visual stream. However, the neural constituents and their interactions that allow us to identify written words are not well understood. Using direct in…

Illusory own body perceptions mapped in the cingulate cortex—An intracranial stimulation study Open
Body awareness is the result of sensory integration in the posterior parietal cortex; however, other brain structures are part of this process. Our goal is to determine how the cingulate cortex is involved in the representation of our body…

Laser ablation for mesial temporal lobe epilepsy: Surgical and cognitive outcomes with and without mesial temporal sclerosis Open
Summary Objectives Laser interstitial thermal therapy ( LITT ) is a minimally invasive surgical technique for focal epilepsy. A major appeal of LITT is that it may result in fewer cognitive deficits, especially when targeting dominant hemi…

Seizure onset predicts its type Open
Summary Objective Epilepsy is characterized by transient alterations in brain synchronization resulting in seizures with a wide spectrum of manifestations. Seizure severity and risks for patients depend on the evolution and spread of the h…

Intrusive Thoughts Elicited by Direct Electrical Stimulation during Stereo-Electroencephalography Open
Cortical direct electrical stimulation (DES) is a method of brain mapping used during invasive presurgical evaluation of patients with intractable epilepsy. Intellectual auras like intrusive thoughts, also known as forced thinking (FT), ha…
