Differential contributions of dorso-ventral and rostro-caudal prefrontal white matter tracts to cognitive control in healthy older adults. [PDF]

open access: yesPLoS ONE, 2013
Prefrontal cortex mediates cognitive control by means of circuitry organized along dorso-ventral and rostro-caudal axes. Along the dorso-ventral axis, ventrolateral PFC controls semantic information, whereas dorsolateral PFC encodes task rules. Along the

Load-dependent activation of bilateral prefrontal cortex: an fNIRS study

open access: yesDi-san junyi daxue xuebao, 2022
Objective To investigate the load-dependent activation in bilateral prefrontal cortex (PFC) during working memory tasks by functional near-infrared spectroscopy (fNIRS). Methods Thirty-four undergraduates (17 males and 17 females) completed a standard N-

Your verbal questions beginning with 'what' will rapidly deactivate the left prefrontal cortex of listeners

open access: yesScientific Reports, 2021
The left prefrontal cortex is essential for verbal communication. It remains uncertain at what timing, to what extent, and what type of phrase initiates left-hemispheric dominant prefrontal activation during comprehension of spoken sentences.

Attention-dependent modulation of cortical taste circuits revealed by granger causality with signal-dependent noise [PDF]

open access: yes, 2013
We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

Hyperactivity of medial prefrontal cortex pyramidal neurons occurs in a mouse model of early-stage Alzheimer’s disease without β-amyloid accumulation

open access: yesFrontiers in Pharmacology, 2023
The normal function of the medial prefrontal cortex (mPFC) is essential for regulating neurocognition, but it is disrupted in the early stages of Alzheimer’s disease (AD) before the accumulation of Aβ and the appearance of symptoms.

Subtle alterations in brain anatomy may change an individual's personality in chronic pain. [PDF]

open access: yesPLoS ONE, 2014
It is well established that gross prefrontal cortex damage can affect an individual's personality. It is also possible that subtle prefrontal cortex changes associated with conditions such as chronic pain, and not detectable until recent advances in ...

Connectivity-based parcellation of the thalamus explains specific cognitive and behavioural symptoms in patients with bilateral thalamic infarct [PDF]

open access: yes, 2013
A novel approach based on diffusion tractography was used here to characterise the cortico-thalamic connectivity in two patients, both presenting with an isolated bilateral infarct in the thalamus, but exhibiting partially different cognitive and ...

Cerebral cortical thickness changes in patients with end-stage renal disease without cognitive dysfunction

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2018
Objective To investigate the changes of cerebral cortical thickness in patients with end-stage renal disease (ESRD) and the relationship between cortical thickness and kidney function.

Forebrain NR2B overexpression facilitating the prefrontal cortex long-term potentiation and enhancing working memory function in mice. [PDF]

open access: yesPLoS ONE, 2011
Prefrontal cortex plays an important role in working memory, attention regulation and behavioral inhibition. Its functions are associated with NMDA receptors.
