Non-reward neural mechanisms in the orbitofrontal cortex [PDF]

open access: yes, 2016
Single neurons in the primate orbitofrontal cortex respond when an expected reward is not obtained, and behaviour must change. The human lateral orbitofrontal cortex is activated when non-reward, or loss occurs.

Localizing value of verbal automatisms, vocal automatisms, singing, and humming: A systematic review

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective We performed a systematic review of the localizing and lateralizing value of verbal automatisms, vocal automatisms, ictal singing, and humming in focal epilepsy with the view to summarize the state‐of‐the‐art clinico‐anatomical correlations in the field and help guide interpretation of ictal semiology within the framework of ...

Social Signals in Primate Orbitofrontal Cortex [PDF]

open access: yesCurrent Biology, 2012
Primate evolution produced an increased capacity to respond flexibly to varying social contexts as well as expansion of the prefrontal cortex. Despite this association, how prefrontal neurons respond to social information remains virtually unknown. People with damage to their orbitofrontal cortex (OFC) struggle to recognize facial expressions, make ...

Direct cortical stimulation–evoked symptoms in the human temporal pole: A systematic review

open access: yesEpileptic Disorders, EarlyView.
Abstract The temporal pole represents a key node within temporolimbic networks and may contribute to seizure generation in temporal lobe epilepsy. Direct cortical stimulation (DCS), performed during intracranial presurgical evaluation, is a valuable method for delineating the seizure onset zone by reproducing electro‐clinical features of a patient's ...

Neuro-cognitive models of aggression, the antisocial personality disorders and psychopathy [PDF]

open access: yes, 2001
This paper considers neurocognitive models of aggression and relates them to explanations of the antisocial personality disorders. Two forms of aggression are distinguished: reactive aggression elicited in response to frustration/threat and goal directed,

Localizing value of ictal déjà vu, déjà vécu, dreamy state and reminiscence: A systematic review

open access: yesEpileptic Disorders, EarlyView.
Abstract We performed a systematic review of the literature regarding the localization value of déjà vu (DV), déjà vécu, dreamy state and reminiscence in focal epilepsy, with the aim to summarize the state‐of‐the‐art anatomo‐electroclinical correlations in the field and help guide interpretation of ictal semiology within the framework of pre‐surgical ...

Novel diagnostic tools for identifying cognitive impairment using olfactory-stimulated functional near-infrared spectroscopy: patient-level, single-group, diagnostic trial

open access: yesAlzheimer’s Research & Therapy, 2022
Introduction Basic studies suggest that olfactory dysfunction and functional near-infrared spectroscopy (fNIRS) can be used as tools for the diagnosis of mild cognitive impairment (MCI); however, real-world evidence is lacking.

High incidence of Y‐chromosome mosaicism in male and female individuals with mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is an underrecognized pediatric cortical lesion associated with somatic X‐linked SLC35A2 variants in approximately 50% of individuals. The genetic etiology in individuals without detectable SLC35A2 mutations remains undefined, which limits
