Individual‐specific resting‐state networks predict language dominance in drug‐resistant epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to reliably estimate individual‐specific resting‐state cortical networks and determine whether language network topography can predict task‐based language dominance in drug‐resistant epilepsy. Methods We utilized a multisession hierarchical Bayesian model (MS‐HBM) trained on drug‐resistant epilepsy patients ...

Absence of Spatial Tuning in the Orbitofrontal Cortex

open access: yesPLoS ONE, 2014
There is limited data in the literature to explicitly support the notion that neurons in OFC are truly action-independent in their coding. We set out to specifically test the hypothesis that OFC value-related neurons in area 13 m of the monkey do not carry information about the action required to obtain that reward--that activity in this area ...

Orbitofrontal Cortex Pathology in Alzheimer's Disease [PDF]

open access: yesCerebral Cortex, 2000
The orbitofrontal cortex has been examined in Alzheimer's disease (AD) from the viewpoint of neurofibrillary tangle (NFT) pathology, its laminar distribution and topography. NFT pathology in the orbitofrontal cortex is extensive in AD. In cases with extensive cortical pathology, NFTs extend from the pole of the frontal lobe to the orbitoinsular ...

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

open access: yesEpilepsia, 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).

16p11 Duplication Disrupts Hippocampal-Orbitofrontal-Amygdala Connectivity, Revealing a Neural Circuit Endophenotype for Schizophrenia

open access: yesCell Reports, 2020
Summary: Chromosome 16p11.2 duplications dramatically increase risk for schizophrenia, but the mechanisms remain largely unknown. Here, we show that mice with an equivalent genetic mutation (16p11.2 duplication mice) exhibit impaired hippocampal ...

Complementary predictive value of electromagnetic source imaging and hemodynamic responses in epilepsy surgery: A quantitative spatial analysis

open access: yesEpilepsia, EarlyView.
Abstract Objective Accurate presurgical evaluation should assess not only the location but also the spatial extent of epileptic activity relative to the surgical cavity, a practical approximation of the epileptogenic zone. We evaluated how electromagnetic source imaging (EMSI) and hemodynamic responses to epileptic discharges relate to the surgical ...

Visual functions of the orbitofrontal cortex

open access: yes, 2015
The primate orbitofrontal cortex receives inputs directly from the inferior temporal visual cortex. The orbitofrontal cortex contains visual neurons that learn in one trial which visual object is associated with a reward such as a taste and represent ...

Electroclinical features and dynamic network connectivity of orbitofrontal epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Orbitofrontal epilepsy (OFE) is rare and underrecognized. This study aims to characterize electroclinical features and dynamic network connectivity of OFE and subtypes. Methods We retrospectively analyzed 17 patients with OFE who underwent stereoelectroencephalographic (SEEG) electrode implantation and epilepsy surgery at our center.

Clinical significance of subclinical seizures in epilepsy presurgical evaluation: A systematic review and meta‐analysis

open access: yesEpilepsia, EarlyView.
Abstract Objective Subclinical seizures (SCSs) remain an understudied aspect of presurgical evaluation in patients with drug‐resistant epilepsy (DRE), with uncertain prevalence, distribution among epilepsy types, and predictive value for surgical outcomes.

MPH-Induced Changes in Right Frontal Metabolism

open access: yesPediatric Neurology Briefs, 1999
The effects of methylphenidate (MPH), a drug that increases dopamine, on brain glucose metabolism in 20 cocaine abusers was studied using PET scans and measurements of D2 receptors at the Brookhaven National Laboratory, the State University of New York ...
