THE PREFRONTAL CORTEX. [PDF]

open access: yesBrain, 1999
By Joaquin M. Fuster. 1997. Pp. 352. Philadelphia: Lippincott-Raven.Price £60. ISBN 0-397-51849-8. In the first edition of The Prefrontal Cortex the author set out his hypothesis concerning the functions of the prefrontal association cortex. These are conceived as being not modality specific but as integrative in nature, orchestrating the \`sensory ...

Impaired Oxygenation of the Prefrontal Cortex During Verbal Fluency Task in Young Adults With Major Depressive Disorder and Suicidality: A Functional Near-Infrared Spectroscopy Study

open access: yesFrontiers in Psychiatry, 2022
BackgroundFew previous studies have focused on prefrontal activation in young adults diagnosed with major depressive disorder (MDD) and suicidality via functional near-infrared spectroscopy (fNIRS).Materials and MethodsA total of 59 healthy controls (HCs)

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

open access: yesPLoS 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 ...

Neuromodulation of Persistent Activity and Working Memory Circuitry in Primate Prefrontal Cortex by Muscarinic Receptors

open access: yesFrontiers in Neural Circuits, 2021
Neuromodulation by acetylcholine plays a vital role in shaping the physiology and functions of cerebral cortex. Cholinergic neuromodulation influences brain-state transitions, controls the gating of cortical sensory stimulus responses, and has been shown

Functional organization and visual representations in human ventral lateral prefrontal cortex

open access: yesFrontiers in Psychology, 2013
Recent neuroimaging studies in both human and non-human primates have identified face selective activation in the ventral lateral prefrontal cortex even in the absence of working memory demands.

Integrative Modeling of Prefrontal Cortex

open access: yesJournal of Cognitive Neuroscience, 2017
AbstractpFC is generally regarded as a region critical for abstract reasoning and high-level cognitive behaviors. As such, it has become the focus of intense research involving a wide variety of subdisciplines of neuroscience and employing a diverse range of methods.

Bilinearity, rules, and prefrontal cortex [PDF]

open access: yesFrontiers in Computational Neuroscience, 2007
Humans can be instructed verbally to perform computationally complex cognitive tasks; their performance then improves relatively slowly over the course of practice. Many skills underlie these abilities; in this paper, we focus on the particular question of a uniform architecture for the instantiation of habitual performance and the storage, recall, and

More subjects are required for ventrolateral than dorsolateral prefrontal TMS because of intolerability and potential drop-out.

open access: yesPLoS ONE, 2019
Transcranial magnetic stimulation (TMS) of the human lateral prefrontal cortex, particularly the ventral region, often causes considerable discomfort to subjects.

Curcumin Ameliorates the Cd-Induced Anxiety-like Behavior in Mice by Regulating Oxidative Stress and Neuro-Inflammatory Proteins in the Prefrontal Cortex Region of the Brain

open access: yesAntioxidants, 2021
Age-related neurodegenerative diseases and vascular dementia are major challenges to the modern health care system. Most neurodegenerative diseases are associated with impaired spatial working memory and anxiety-like behavior.

Increased Prefrontal Activation During Verbal Fluency Task After Repetitive Transcranial Magnetic Stimulation Treatment in Depression: A Functional Near-Infrared Spectroscopy Study

open access: yesFrontiers in Psychiatry, 2022
BackgroundPrevious studies have shown the clinical effect of 2 Hz repetitive transcranial magnetic stimulation (rTMS) for depression; however, its underlying neural mechanisms are poorly understood.
