Neural coding of tactile decisions in the human prefrontal cortex [PDF]

open access: yes, 2006
The neural processes underlying tactile decisions in the human brain remain elusive. We addressed this question in a functional magnetic resonance imaging study using a somatosensory discrimination task, requiring participants to compare the frequency of

Neuropsychology of prefrontal cortex

open access: yesIndian Journal of Psychiatry, 2008
The history of clinical frontal lobe study is long and rich which provides valuable insights into neuropsychologic determinants of functions of prefrontal cortex (PFC). PFC is often classified as multimodal association cortex as extremely processed information from various sensory modalities is integrated here in a precise fashion to form the ...

Performance- and stimulus-dependent oscillations in monkey prefrontal cortex during short-term memory [PDF]

open access: yes, 2009
Short-term memory requires the coordination of sub-processes like encoding, retention, retrieval and comparison of stored material to subsequent input. Neuronal oscillations have an inherent time structure, can effectively coordinate synaptic integration

Hyperconnectivity of the ventromedial prefrontal cortex in obsessive-compulsive disorder

open access: yesBrain and Neuroscience Advances, 2018
Neuroimaging research has highlighted maladaptive thalamo-cortico-striatal interactions in obsessive-compulsive disorder as well as a more general deficit in prefrontal functioning linked with compromised executive functioning.

Anterior Prefrontal Contributions to Implicit Attention Control

open access: yesBrain Sciences, 2012
Prefrontal cortex function has traditionally been associated with explicit executive function. Recently, however, evidence has been presented that lateral prefrontal cortex is also involved in high-level cognitive processes such as task set selection or ...

Perturbation of the right prefrontal cortex disrupts interference control

open access: yesNeuroImage, 2020
Resolving cognitive interference is central for successful everyday cognition and behavior. The Stroop task is a classical measure of cognitive interference.

Ventrolateral prefrontal cortex activation and attention bias in response to angry faces in adolescents with generalized anxiety disorder [PDF]

open access: yes, 2006
OBJECTIVE: While adolescent anxiety disorders represent prevalent, debilitating conditions, few studies have explored their brain physiology. Using event-related functional magnetic resonance imaging (fMRI) and a behavioral measure of attention to angry ...

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)

Functional differentiation within the monkey cortex as revealed by near-infrared spectroscopy [PDF]

open access: yes, 2008
The role of prefrontal cortex in working memory (WM) is well established. However, questions remain regarding the topography and “domain-specific differentiation” of different types of information processing in the cortex.

The topology of connections between rat prefrontal, motor and sensory cortices

open access: yesFrontiers in Systems Neuroscience, 2014
The connections of prefrontal cortex (PFC) were investigated in the rat brain to determine the order and location of input and output connections to motor and somatosensory cortex.
