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

, 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 ...

Hyperconnectivity of the ventromedial prefrontal cortex in obsessive-compulsive disorder

Brain 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.

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

Frontiers 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.

Perturbation of the right prefrontal cortex disrupts interference control

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

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

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

Spatial selectivity in human ventrolateral prefrontal cortex [PDF]

, 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

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

PLoS 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

Frontiers 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

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

Frontiers 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)

Gray-matter volume, midbrain dopamine D2/D3 receptors and drug craving in methamphetamine users. [PDF]

, 2015
Dysfunction of the mesocorticolimbic system has a critical role in clinical features of addiction. Despite evidence suggesting that midbrain dopamine receptors influence amphetamine-induced dopamine release and that dopamine is involved in ...
