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 ...

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.

Comparison of prefrontal atrophy and episodic memory performance in dysexecutive Alzheimer’s disease and behavioural-variant frontotemporal dementia [PDF]

, 2016
Alzheimer’s disease (AD) sometimes presents with prominent executive dysfunction and associated prefrontal cortex atrophy. The impact of such executive deficits on episodic memory performance as well as their neural correlates in AD, however, remains ...

Decoding subjective decisions from orbitofrontal cortex [PDF]

Nature Neuroscience, 2016
When making a subjective choice, the brain must compute a value for each option and compare those values to make a decision. The orbitofrontal cortex (OFC) is critically involved in this process, but the neural mechanisms remain obscure, in part due to limitations in our ability to measure and control the internal deliberations that can alter the ...

The Orbitofrontal Cortex in Temporal Cognition [PDF]

Behavioral Neuroscience, 2020
AbstractOne of the most important factors in decision making is estimating the value of available options. Subregions of the prefrontal cortex, including the orbitofrontal cortex (OFC), have been deemed essential for this process. Value computations require a complex integration across numerous dimensions, including, reward magnitude, effort, internal ...

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 ...

Addressing the selective role of distinct prefrontal areas in response suppression: A study with brain tumor patients [PDF]

, 2017
The diverging evidence for functional localization of response inhibition within the prefrontal cortex might be justified by the still unclear involvement of other intrinsically related cognitive processes like response selection and sustained attention.

The orbitofrontal cortex and response selection [PDF]

Annals of the New York Academy of Sciences, 2011
Orbitofrontal cortex (OFC) function is often characterized in terms of stimulus–reward mapping; however, more recent evidence suggests that the OFC may play a role in selecting and representing extended actions. First, previously encoded reward associations in the OFC could be used to inform responding in novel but similar situations.

Autism spectrum traits in normal individuals : a preliminary VBM analysis [PDF]

, 2015
In light of the new DSM-5 autism spectrum disorders diagnosis in which the autism spectrum reflects a group of neurodevelopmental disorders existing on a continuum from mild to severe expression of autistic traits, and recent empirical findings showing a

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
