Objectives: Resective surgery in drug-resistant focal epilepsy (DRFE) requires extensive evaluation to localize the epileptogenic zone (EZ). When non-invasive phase 1 assessments (electroencephalography, EEG; magnetic resonance imaging, MRI; and F-Fluorodeoxyglucose-positron emission tomography, [F]FDG-PET) are inconclusive for EZ localization, invasive investigations such as stereo-EEG (SEEG) are necessary. Epileptogenicity maps (Ems) visualize the EZ using SEEG-identified ictal high-frequency oscillations (iHFOs).

Purpose: This work investigates the presence of common anatomic regions associated with interictal activity in patients with hyperkinetic seizures type I by means of concurrent electroencephalography and functional magnetic resonance imaging.
Methods: Six patients with hyperkinetic seizures type I were evaluated with video-EEG and electroencephalography and functional magnetic resonance imaging in the context of their presurgical evaluation. Statistical Parametric Mapping was used to perform a correlation study between the occurrence of interictal spikes on EEG and suprathreshold blood oxygen level-dependent changes in the whole-brain volume.

Background: Connectomic modeling studies are expanding understanding of the brain networks that are modulated by deep brain stimulation (DBS) therapies. However, explicit integration of these modeling results into prospective neurosurgical planning is only beginning to evolve. One challenge of employing connectomic models in patient-specific surgical planning is the inherent 3D nature of the results, which can make clinically useful data integration and visualization difficult.

Department of Neurological Surgery, UT Southwestern Medical Center, Dallas, TX, USA.
Background: Deep brain stimulation (DBS) and other neuromodulatory techniques are being increasingly utilized to treat refractory neurologic and psychiatric disorders.
Objective: /Hypothesis: To better understand the circuit-level pathophysiology of treatment-resistant depression (TRD) and treat the network-level dysfunction inherent to this challenging disorder, we adopted an approach of inpatient intracranial monitoring borrowed from the epilepsy surgery field.
Methods: We implanted 3 patients with 4 DBS leads (bilateral pair in both the ventral capsule/ventral striatum and subcallosal cingulate) and 10 stereo-electroencephalography (sEEG) electrodes targeting depression-relevant network regions.
