Aberrant Functional Connectivity of the Orbitofrontal Cortex Is Associated With Excited Symptoms in First-Episode Drug-Naïve Patients With Schizophrenia

open access: yesFrontiers in Psychiatry, 2022
BackgroundSchizophrenia (SZ) is associated with the highest disability rate among serious mental disorders. Excited symptoms are the core symptoms of SZ, which appear in the early stage, followed by other stages of the disease subsequently.

The orbitofrontal cortex and response selection [PDF]

open access: yesAnnals of the New York Academy of Sciences, 2011
Orbitofrontal cortex (OFC) function is often characterized in terms of stimulus–reward mapping; however, more recent evidence suggests that the OFC may play a role in selecting and representing extended actions. First, previously encoded reward associations in the OFC could be used to inform responding in novel but similar situations.

Encoding touch and the orbitofrontal cortex [PDF]

open access: yesHuman Brain Mapping, 2009
AbstractLesion studies on nonhuman primates utilizing recognition memory tests have shown that the orbitofrontal cortex is critical for the encoding of novel information, and anatomical studies have shown that the orbitofrontal cortex forms part of a mnemonic circuit that connects limbic medial temporal areas with higher‐order lateral frontal cortical ...

The stressed orbitofrontal cortex.

open access: yesBehavioral Neuroscience, 2021
Stressor exposure causes dendritic remodeling on excitatory neurons in multiple regions of the brain, including the orbitofrontal cortex (OFC). Additionally, stressor and exogenous stress hormone exposure impair cognitive functions that are dependent on the OFC.

Higher Peripheral Inflammation Is Associated With Lower Orbitofrontal Gamma Power in Chronic Tinnitus

open access: yesFrontiers in Behavioral Neuroscience, 2022
Chronic tinnitus, the continuous perception of a phantom sound, is a highly prevalent audiological symptom, for which the underlying pathology has not yet been fully understood.

Orbitofrontal Cortex and Memory Formation [PDF]

open access: yesNeuron, 2002
Which one of the many regions of the anatomically heterogeneous prefrontal cortex is part of the critical core of the neural circuit for encoding? This positron emission tomography (PET) experiment measured changes in cerebral blood flow (CBF) in normal human participants during the presentation of abstract visual information in four conditions that ...

Chemosensory Learning in the Cortex

open access: yesFrontiers in Systems Neuroscience, 2011
Taste is a primary reinforcer. Olfactory-taste and visual-taste association learning takes place in the primate including human orbitofrontal cortex to build representations of flavour.

The Orbitofrontal Cortex and Reward [PDF]

open access: yesCerebral Cortex, 2000
The primate orbitofrontal cortex contains the secondary taste cortex, in which the reward value of taste is represented. It also contains the secondary and tertiary olfactory cortical areas, in which information about the identity and also about the reward value of odors is represented. The orbitofrontal cortex also receives information about the sight

Medial-lateral Organization of the Orbitofrontal Cortex [PDF]

open access: yesJournal of Cognitive Neuroscience, 2014
Abstract Emerging evidence suggests that specific cognitive functions localize to different subregions of OFC, but the nature of these functional distinctions remains unclear. One prominent theory, derived from human neuroimaging, proposes that different stimulus valences are processed in separate orbital regions, with medial and lateral

Altered sulcogyral patterns of orbitofrontal cortex in a large cohort of patients with schizophrenia

open access: yesnpj Schizophrenia, 2017
Abnormalities in prenatal brain development contribute to schizophrenia vulnerability. Orbitofrontal cortex sulcogyral patterns are largely determined during prenatal development, and four types of orbitofrontal cortex sulcogyral patterns have been ...
