Associations between psychopathic traits and brain activity during instructed false responding [PDF]

, 2017
Lying is one of the characteristic features of psychopathy, and has been recognized in clinical and diagnostic descriptions of the disorder, yet individuals with psychopathic traits have been found to have reduced neural activity in many of the brain ...

Neural mechanisms of economic choices in mice [PDF]

, 2020
Economic choices entail computing and comparing subjective values. Evidence from primates indicates that this behavior relies on the orbitofrontal cortex. Conversely, previous work in rodents provided conflicting results. Here we present a mouse model of

Orbitofrontal Cortex Encodes Preference for Alcohol [PDF]

eneuro, 2020
AbstractOrbitofrontal cortex (OFC) plays a key role in representation and regulation of reward value, preference, and seeking. OFC function is disrupted in drug use and dependence, but its specific role in alcohol use disorders has not been thoroughly studied. In alcohol-dependent humans OFC activity is increased by alcohol cue presentation.

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.

How the brain represents the reward value of fat in the mouth. [PDF]

, 2009
The palatability and pleasantness of the sensory properties of foods drive food selection and intake and may contribute to overeating and obesity. Oral fat texture can make food palatable and pleasant.

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 ...

Functional connectivity of the human amygdala in health and in depression [PDF]

, 2018
To analyze the functioning of the amygdala in depression, we performed the first voxel-level resting state functional-connectivity neuroimaging analysis of depression of voxels in the amygdala with all other voxels in the brain, with 336 patients with ...

The State of the Orbitofrontal Cortex [PDF]

Neuron, 2015
State representation is fundamental to behavior. However, identifying the true state of the world is challenging when explicit cues are ambiguous. Here, Bradfield and colleagues show that the medial OFC is critical for using associative information to discriminate ambiguous states.

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.

Emotional face expression modulates occipital-frontal effective connectivity during memory formation in a bottom-up fashion

Frontiers in Behavioral Neuroscience, 2015
This study investigated the role of bottom-up and top-down neural mechanisms in the processing of emotional face expression during memory formation. Functional brain imaging data was acquired during incidental learning of positive (‘happy’), neutral and ...
