Distinct Roles of the Prefrontal and Posterior Parietal Cortices in Response Inhibition
Cell Reports, 2016 The dorsolateral prefrontal cortex and posterior parietal cortex have been implicated in the planning of movements and inhibition of inappropriate responses, though their precise roles in these functions are not known.

Integrative Modeling of Prefrontal Cortex
Journal 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.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Certain frontotemporal lobar degeneration subtypes, including TDP‐A and B, can either occur sporadically or in association with specific genetic mutations. It is uncertain whether syndromic or imaging features previously associated with these patient groups are subtype or genotype specific.

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022 The current study adopted an experimental paradigm of digital span to evaluate acute high‐altitude exposure impairment on working memory. The subjects showed obvious physiological adaptation mechanism at acute altitude. The results of hemodynamic response confirmed the important role of left DLPFC in the process of working memory, revealed abnormal ...

Spatio-Temporal Dynamics of Visual Imagery for Intuitive Brain-Computer Interface [PDF]
arXiv, 2020 Visual imagery is an intuitive brain-computer interface paradigm, referring to the emergence of the visual scene. Despite its convenience, analysis of its intrinsic characteristics is limited. In this study, we demonstrate the effect of time interval and channel selection that affects the decoding performance of the multi-class visual imagery.

Cerebello‐Prefrontal Connectivity Underlying Cognitive Dysfunction in Spinocerebellar Ataxia Type 2
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Spinocerebellar ataxia type 2 (SCA2) is a hereditary cerebellar degenerative disorder, with motor and cognitive symptoms. The constellation of cognitive symptoms due to cerebellar degeneration is named cerebellar cognitive affective syndrome (CCAS), which has increasingly been recognized to profoundly impact patients' quality of life;

Functional connectivity in behavioral variant frontotemporal dementia
Brain and Behavior, Volume 12, Issue 12, December 2022., 2022 Decreased FC in the Salience Network (SN) is the most consistent finding in bvFTD. The brain's functional architecture is less interconnected and efficient in bvFTD. Symptom, behavior, cognition and disease severity are associated with changes in FC. Abstract Introduction Functional connectivity (FC)—which reflects relationships between neural activity

Optogenetic control of genetically-targeted pyramidal neuron activity in prefrontal cortex [PDF]
, 2012 A salient feature of prefrontal cortex organization is the vast diversity of cell types that support the temporal integration of events required for sculpting future responses. A major obstacle in understanding the routing of information among prefrontal neuronal subtypes is the inability to manipulate the electrical activity of genetically defined ...
