Orbitofrontal sulcal and gyrus pattern in human: an anatomical study

Arquivos 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

Frontiers 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]

Neuron, 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.

Lateral orbitofrontal cortex anticipates choices and integrates prior with current information

Nature 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

Frontiers 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

Nature 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.

Spike-Timing of Orbitofrontal Neurons Is Synchronized With Breathing

Frontiers in Cellular Neuroscience, 2018
The orbitofrontal cortex (OFC) has been implicated in a multiplicity of complex brain functions, including representations of expected outcome properties, post-decision confidence, momentary food-reward values, complex flavors and odors.

16p11.2 deletion mice exhibit compromised fronto-temporal connectivity, GABAergic dysfunction, and enhanced attentional ability

Communications Biology, 2023
Autism spectrum disorders are more common in males, and have a substantial genetic component. Chromosomal 16p11.2 deletions in particular carry strong genetic risk for autism, yet their neurobiological impact is poorly characterised, particularly at the ...

The within-subject application of diffusion tensor MRI and CLARITY reveals brain structural changes in Nrxn2 deletion mice

Molecular Autism, 2019
Background Of the many genetic mutations known to increase the risk of autism spectrum disorder, a large proportion cluster upon synaptic proteins. One such family of presynaptic proteins are the neurexins (NRXN), and recent genetic and mouse evidence ...

Brain structure and symptom dimensions in borderline personality disorder

European Psychiatry, 2020
Background.Borderline personality disorder (BPD) presents with symptoms across different domains, whose neurobiology is poorly understood.Methods.We applied voxel-based morphometry on high-resolution magnetic resonance imaging scans of 19 female BPD ...
