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 ...

Resolution of Uncertainty in Prefrontal Cortex [PDF]

open access: yesNeuron, 2006
Making optimal decisions in the face of uncertain or incomplete information arises as a common problem in everyday behavior, but the neural processes underlying this ability remain poorly understood. A typical case is navigation, in which a subject has to search for a known goal from an unknown location.

Spatial selectivity in human ventrolateral prefrontal cortex [PDF]

open access: yes, 2005
The functional organization of lateral prefrontal cortex is not well understood, and there is debate as to whether the dorsal and ventral aspects mediate distinct spatial and non-spatial functions, respectively. We show for the first time that recordings

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.

Speed-accuracy strategy regulations in prefrontal tumor patients [PDF]

open access: yes, 2016
The ability to flexibly switch between fast and accurate decisions is crucial in everyday life. Recent neuroimaging evidence suggested that left lateral prefrontal cortex plays a role in switching from a quick response strategy to an accurate one ...

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 ...

Alcohol and the Prefrontal Cortex [PDF]

open access: yes, 2010
The prefrontal cortex occupies the anterior portion of the frontal lobes and is thought to be one of the most complex anatomical and functional structures of the mammalian brain. Its major role is to integrate and interpret inputs from cortical and sub-cortical structures and use this information to develop purposeful responses that reflect both ...

The short and long of it: neural correlates of temporal-order memory for autobiographical events [PDF]

open access: yes, 2008
Previous functional neuroimaging studies of temporal-order memory have investigated memory for laboratory stimuli that are causally unrelated and poor in sensory detail.

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.

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.
