Attention-dependent modulation of cortical taste circuits revealed by Granger causality with signal-dependent noise. [PDF]
PLoS Computational Biology, 2013 We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

Reduced regional brain cortical thickness in patients with heart failure. [PDF]
, 2015 AimsAutonomic, cognitive, and neuropsychologic deficits appear in heart failure (HF) subjects, and these compromised functions depend on cerebral cortex integrity in addition to that of subcortical and brainstem sites.

Current Biology, 2018 The orbitofrontal cortex is a large and heterogeneous cortical area on the ventral surface of the frontal lobe and is intimately involved in emotion and executive function. In this Primer, Peter Rudebeck and Erin Rich summarize our understanding of the mechanisms through which orbitofrontal cortex adaptively shapes decision making and affective ...

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 ...

The magical orbitofrontal cortex. [PDF]
Behavioral Neuroscience, 2021 This special issue, commissioned after the 4th Quadrennial Meeting on Orbitofrontal Cortex Function held in Paris in November of 2019 (https://ofc2019.sciencesconf.org/), is intended to provide a snapshot of this ongoing transformation; we hope that the ideas presented herein will provide a foundation for the next stage in the evolution of our ...

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.

Orbitofrontal Cortex Assigns Credit Wisely [PDF]
Neuron, 2010 Damage in the orbitofrontal cortex impairs the ability to switch behaviors when their outcomes change, but the cause of these deficits remained unknown. In this issue of Neuron, Walton et al. demonstrate a key role of the primate orbitofrontal cortex in disambiguating the relationship between multiple choices and their outcomes.
