Abnormal Spontaneous Neural Activity in Obsessive-Compulsive Disorder: A Resting-State Functional Magnetic Resonance Imaging Study. [PDF]

PLoS ONE, 2013
Neuroimaging studies of obsessive-compulsive disorder have found abnormalities in orbitofronto-striato-thalamic circuitry, including the orbitofrontal cortex, anterior cingulate cortex, caudate, and thalamus, but few studies have explored abnormal ...

Chronology of auditory processing and related co-activation in the orbitofrontal cortex depends on musical expertise

Frontiers in Neuroscience, 2023
IntroductionThe present study aims to explore the extent to which auditory processing is reflected in the prefrontal cortex.MethodsUsing magnetoencephalography (MEG), we investigated the chronology of primary and secondary auditory responses and ...

Risk-taking in humans and the medial orbitofrontal cortex reward system

NeuroImage, 2022
Risk-taking differs between humans, and is associated with the personality measures of impulsivity and sensation-seeking. To analyse the brain systems involved, self-report risk-taking, resting state functional connectivity, and related behavioral ...

Obesity is associated with reduced orbitofrontal cortex volume: A coordinate-based meta-analysis

NeuroImage: Clinical, 2020
Neural models of obesity vary in their focus upon prefrontal and striatal differences. Animal and human studies suggest that differential functioning of the orbitofrontal cortex is associated with obesity.

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

Frontiers 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.

Behavioral flexibility is associated with changes in structure and function distributed across a frontal cortical network in macaques.

PLoS Biology, 2020
One of the most influential accounts of central orbitofrontal cortex-that it mediates behavioral flexibility-has been challenged by the finding that discrimination reversal in macaques, the classic test of behavioral flexibility, is unaffected when ...

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

Frontiers 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.

Chemosensory Learning in the Cortex

Frontiers 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.

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

npj 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 ...

Chronic Unpredictable Stress Reduces Immunostaining for Connexins 43 and 30 and Myelin Basic Protein in the Rat Prelimbic and Orbitofrontal Cortices

Chronic Stress, 2018
Background Astrocytes and oligodendrocytes are pathologically altered in dorsolateral prefrontal and orbitofrontal cortices in major depressive disorder.
