Cortical and Subcortical Alterations in Medication Overuse Headache

open access: yesFrontiers 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 ...

Spatial Representations in Rat Orbitofrontal Cortex [PDF]

open access: yesThe Journal of Neuroscience, 2021
The orbitofrontal cortex (OFC) and hippocampus share striking cognitive and functional similarities. As a result, both structures have been proposed to encode "cognitive maps" that provide useful scaffolds for planning complex behaviors. However, while this function has been exemplified by spatial coding in neurons of hippocampal regions-particularly ...

Orbitofrontal sulcal and gyrus pattern in human: an anatomical study

open access: yesArquivos de Neuro-Psiquiatria, 2015
The anatomical characterization of the orbitofrontal cortex in human is limited in literature instead of many functional and clinical studies involving it. Objective Anatomically define the orbitofrontal region aiming to possible neurosurgical treatments

The neural correlation of emotion recognition ability and depressive symptoms–evidence from the HCP database

open access: yesFrontiers in Psychiatry, 2023
IntroductionNegative bias of emotional face is the core feature of depression, but its underlying neurobiological mechanism is still unclear. The neuroimaging findings of negative emotional recognition and depressive symptoms are inconsistent.MethodsThe ...

Of Pathways, Processes, and Orbitofrontal Cortex [PDF]

open access: yesNeuron, 2019
Orbitofrontal cortex (OFC) predicts the consequences of our actions and updates our expectations based on experienced outcomes. In this issue of Neuron, Groman et al. (2019) precisely ablate pathways between the OFC, amygdala, and nucleus accumbens to reveal their separable contributions to reinforcement learning.

A specific and rapid neural signature for parental instinct [PDF]

open access: yes, 2008
Darwin originally pointed out that there is something about infants which prompts adults to respond to and care for them, in order to increase individual fitness, i.e. reproductive success, via increased survivorship of one's own offspring.

Lateral orbitofrontal cortex anticipates choices and integrates prior with current information

open access: yesNature Communications, 2017
The orbitofrontal cortex encodes outcomes, expected rewards and values, but it is unclear how this region uses this information to inform action selection. Here, the authors show that lateral orbitofrontal cortex anticipates upcoming choices and combines

Olfactory consciousness and gamma oscillation couplings across the olfactory bulb, olfactory cortex and orbitofrontal cortex

open access: yesFrontiers in Psychology, 2013
The orbitofrontal cortex receives multi-modality sensory inputs, including olfactory input, and is thought to be involved in conscious perception of the olfactory image of objects.

A structural and functional subdivision in central orbitofrontal cortex

open access: yesNature Communications, 2022
A portion of the orbitofrontal cortex can be subdivided by its connectivity with the posterior cingulate cortex. This connectivity-based parcellation shows differences in functional connectivity and economic choice signals.

Deciding when to decide : time-variant sequential sampling models explain the emergence of value-based decisions in the human brain [PDF]

open access: yes, 2012
The cognitive and neuronal mechanisms of perceptual decision making have been successfully linked to sequential sampling models. These models describe the decision process as a gradual accumulation of sensory evidence over time. The temporal evolution of
