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 ...

Poor performance on the Iowa gambling task in children with obsessive-compulsive disorder

Annals of General Psychiatry, 2012
Background Several lines of evidence implicate orbitofrontal cortex dysfunction in the pathophysiology of obsessive-compulsive disorder (OCD). The purpose of this study was to investigate neuropsychological dysfunction of the orbitofrontal cortex in ...

Decreased brain connectivity in smoking contrasts with increased connectivity in drinking

eLife, 2019
In a group of 831 participants from the general population in the Human Connectome Project, smokers exhibited low overall functional connectivity, and more specifically of the lateral orbitofrontal cortex which is associated with non-reward mechanisms ...

Striatum-Centered Fiber Connectivity Is Associated with the Personality Trait of Cooperativeness. [PDF]

PLoS ONE, 2016
Cooperativeness is an essential behavioral trait evolved to facilitate group living. Social and cognitive mechanisms involved in cooperation (e.g., motivation, reward encoding, action evaluation, and executive functions) are sub-served by the striatal ...

Sensation-seeking is related to functional connectivities of the medial orbitofrontal cortex with the anterior cingulate cortex

NeuroImage, 2020
Sensation-seeking is a multifaceted personality trait with components that include experience-seeking, thrill and adventure seeking, disinhibition, and susceptibility to boredom, and is an aspect of impulsiveness.

Aversive event anticipation affects connectivity between the ventral striatum and the orbitofrontal cortex in an fMRI avoidance task. [PDF]

PLoS ONE, 2013
Ability to anticipate aversive events is important for avoiding dangerous or unpleasant situations. The motivation to avoid an event is influenced by the incentive salience of an event-predicting cue. In an avoidance fMRI task we used tone intensities to

Assessment of olfactory information in the human brain using 7-Tesla functional magnetic resonance imaging

NeuroImage, 2021
Olfaction could prove to be an early marker of neurodegenerative diseases, including Alzheimer's and Parkinson's diseases. To use olfaction for disease diagnosis, elucidating the standard olfactory functions in healthy humans is necessary.

Cortical and Subcortical Alterations in Medication Overuse Headache

Frontiers in Neurology, 2018
Medication-overuse headache is an increasing problem in headache clinics and therapy includes drug withdrawal. Although it has been shown that the orbitofrontal cortex is hypo-metabolic and exhibits less gray matter in these patients the functional role ...

Olfactory Loss and Brain Connectivity after COVID-19: Structural Follow-Up at One Year

Neural Plasticity, 2023
The structural connectivity from the primary olfactory cortex to the main secondary olfactory areas was previously reported as relatively increased in the medial orbitofrontal cortex in a cohort of 27 recently SARS-CoV-2-infected (COV+) subjects, of ...
