The Posterior Cingulate Cortex Reflects the Impact of Anxiety on Drift Rates During Cognitive Processing

Autor: Adam X. Gorka, Ryan T. Philips, Salvatore Torrisi, Leonardo Claudino, Katherine Foray, Christian Grillon, Monique Ernst

Publikováno v: Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. 8:445-451

Generally, anxiety is thought to impair ongoing cognitive operations. Surprisingly, however, anxiety has been shown to improve performance during the Go/NoGo task. Understanding how anxiety can facilitate task performance may shed light on avenues to

Periaqueductal gray matter and medial prefrontal cortex reflect negative prediction errors during differential conditioning

Autor: Adam X Gorka, Ryan T Philips, Salvatore Torrisi, Adrienne Manbeck, Madeline Goodwin, Monique Ernst, Christian Grillon

Publikováno v: Soc Cogn Affect Neurosci

Computational models of associative learning posit that negative prediction errors (PEs) arising from the omission of aversive outcomes weaken aversive Pavlovian associations during differential conditioning and extinction. It is possible that negati

Dynamic Time Warping Identifies Functionally Distinct fMRI Resting State Cortical Networks Specific to VTA and SNc: A Proof of Concept

Autor: Christian Grillon, Salvatore Torrisi, Ryan T. Philips, Monique Ernst, Adam X. Gorka

Publikováno v: Cereb Cortex

Functional connectivity (FC) is determined by similarity between functional magnetic resonance imaging (fMRI) signals from distinct brain regions. However, traditional FC analyses ignore temporal phase differences. Here, we addressed this limitation,

Methylphenidate modulates interactions of anxiety with cognition

Autor: Bari Fuchs, Christian Grillon, Tiffany R. Lago, Adam X. Gorka, Richard C. Reynolds, Claudie Gaillard, Nicholas L. Balderston, Monique Ernst

Publikováno v: Translational Psychiatry
Translational Psychiatry, Vol 11, Iss 1, Pp 1-9 (2021)

While a large body of literature documents the impairing effect of anxiety on cognition, performing a demanding task was shown to be effective in reducing anxiety. Here we explored the mechanisms of this anxiolytic effect by examining how a pharmacol

Prefrontal Responses during Proactive and Reactive Inhibition Are Differentially Impacted by Stress in Anorexia and Bulimia Nervosa

Autor: Christian Grillon, Paul C. Fletcher, Flavia Mancini, Jane Shapleske, Adam X. Gorka, Margaret L. Westwater, Hisham Ziauddeen, Monique Ernst, Jaco Serfontein

Publikováno v: The Journal of Neuroscience

Binge eating is a distressing, transdiagnostic eating disorder symptom associated with impulsivity, particularly in negative mood states. Neuroimaging studies of bulimia nervosa (BN) report reduced activity in frontostriatal regions implicated in sel

Intrinsic functional connectivity of the central nucleus of the amygdala and bed nucleus of the stria terminalis

Autor: Alexander J. Shackman, Christian Grillon, Adam X. Gorka, Salvatore Torrisi, Monique Ernst

Publikováno v: NeuroImage. 168:392-402

The central nucleus of the amygdala (CeA) and bed nucleus of the stria terminalis (BNST), two nuclei within the central extended amygdala, function as critical relays within the distributed neural networks that coordinate sensory, emotional, and cogn

Intrinsic connections between thalamic sub-regions and the lateral prefrontal cortex are differentially impacted by acute methylphenidate

Autor: Christian Grillon, Nicholas L. Balderston, Salvatore Torrisi, Tiffany R. Lago, Adam X. Gorka, Bari Fuchs, Monique Ernst

Publikováno v: Psychopharmacology (Berl)

BACKGROUND: The thalamus is a major target of dopaminergic projections and is densely connected with the prefrontal cortex. A better understanding of how dopamine changes thalamo-cortical communication may shed light on how dopamine supports cognitiv

Resting-state connectivity of the bed nucleus of the stria terminalis and the central nucleus of the amygdala in clinical anxiety

Publikováno v: Journal of psychiatryneuroscience : JPN. 44(5)

Background: The central nucleus of the amygdala and bed nucleus of the stria terminalis are involved primarily in phasic and sustained aversive states. Although both structures have been implicated in pathological anxiety, few studies with a clinical
