Ultrafast oscillations in the human brain and their functional significance

Epilepsia, EarlyView.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

Comparison of volume‐ and surface‐based magnetic resonance imaging morphometry algorithms in the detection of focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Detection of focal cortical dysplasia (FCD) remains a major challenge in presurgical epilepsy diagnostics. Magnetic resonance imaging (MRI) morphometry increasingly improves lesion detection and postsurgical outcomes. The volume‐based Morphometric Analysis Program, version 2018 (MAP18) with integrated artificial neural network and ...

Mindfulness meditation increases interictal epileptiform discharges in meditation‐naïve surgical epilepsy patients

Epilepsia, EarlyView.
Abstract Objective Meditation has widely recognized psychological and neuromodulatory benefits, yet its effects on epileptiform activity remain unclear. This study examined whether novice meditation modulates interictal epileptiform discharges (IEDs) in patients with drug‐resistant epilepsy using intracranial electroencephalography (iEEG).

Frontal lobe connectivity and cognitive impairment in pediatric frontal lobe epilepsy

, 2013
Purpose: Cognitive impairment is frequent in children with frontal lobe epilepsy (FLE), but its etiology is unknown. With functional magnetic resonance imaging (fMRI), we have explored the relationship between brain activation, functional connectivity ...

The dynamic functional connectivity peak index: Detection of interictal epileptic activity with fMRI

Epilepsia, EarlyView.
Abstract Objective Epileptogenic zone (EZ) localization is crucial for surgical treatment of patients with medication‐resistant epilepsy. Although simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) can detect interictal discharges for EZ localization, clinical adoption is limited by the need for specialized ...

Large-scale cortico-subcortical functional networks in focal epilepsies: The role of the basal ganglia

NeuroImage: Clinical, 2017
Objectives: The aim was to describe the contribution of basal ganglia (BG) thalamo-cortical circuitry to the whole-brain functional connectivity in focal epilepsies. Methods: Interictal resting-state fMRI recordings were acquired in 46 persons with focal

Parietal Lobes in Schizophrenia: Do They Matter? [PDF]

, 2011
Objective. Despite observations that abnormal parietal lobe (PL) function is associated with psychotic-like experiences, our knowledge about the nature of PL involvement in schizophrenia is modest.

Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy

Epilepsia, EarlyView.
Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.
