Describing the interplay between anxiety and cognition: from impaired performance under low cognitive load to reduced anxiety under high load.

• Katherine Vytal, Brian R. Cornwell, Nicole E. Arkin, Christian Grillon
• Psychophysiology
• 2012

Anxiety impairs the ability to think and concentrate, suggesting that the interaction between emotion and cognition may elucidate the debilitating nature of pathological anxiety. Using a verbal… (More)

Neuroimaging Support for Discrete Neural Correlates of Basic Emotions: A Voxel-based Meta-analysis

• Katherine Vytal, Stephan Hamann
• Journal of Cognitive Neuroscience
• 2010

What is the basic structure of emotional experience and how is it represented in the human brain? One highly influential theory, discrete basic emotions, proposes a limited set of basic emotions such… (More)

Oxytocin increases anxiety to unpredictable threat

wild-type (WT) littermates (Supplementary Figures 1a–g). In tailsuspension and forced-swimming tests, which are reliable predictors of antidepressant potential, vehicle-treated adult KO or… (More)

The impact of anxiety upon cognition: perspectives from human threat of shock studies

• Oliver J. Robinson, Katherine Vytal, Brian R. Cornwell, Christian Grillon
• Front. Hum. Neurosci.
• 2013

Anxiety disorders constitute a sizeable worldwide health burden with profound social and economic consequences. The symptoms are wide-ranging; from hyperarousal to difficulties with concentrating.… (More)

The adaptive threat bias in anxiety: Amygdala–dorsomedial prefrontal cortex coupling and aversive amplification

• Oliver J. Robinson, Danielle R. Charney, Cassie Overstreet, Katherine Vytal, Christian Grillon
• NeuroImage
• 2012

Functionally, anxiety serves to increase vigilance towards aversive stimuli and improve the ability to detect and avoid danger. We have recently shown, for instance, that anxiety increases the… (More)

The complex interaction between anxiety and cognition: insight from spatial and verbal working memory

• Katherine Vytal, Brian R. Cornwell, Allison M. Letkiewicz, Nicole E. Arkin, Christian Grillon
• Front. Hum. Neurosci.
• 2013

Anxiety can be distracting, disruptive, and incapacitating. Despite problems with empirical replication of this phenomenon, one fruitful avenue of study has emerged from working memory (WM)… (More)

Sustained anxiety increases amygdala-dorsomedial prefrontal coupling: a mechanism for maintaining an anxious state in healthy adults.

• Katherine Vytal, Cassie Overstreet, Danielle R. Charney, Oliver J. Robinson, Christian Grillon
• Journal of psychiatry & neuroscience : JPN
• 2014

BACKGROUND Neuroimaging research has traditionally explored fear and anxiety in response to discrete threat cues (e.g., during fear conditioning). However, anxiety is a sustained aversive state that… (More)

Stress increases aversive prediction error signal in the ventral striatum.

• Oliver J. Robinson, Cassie Overstreet, Danielle R. Charney, Katherine Vytal, Christian Grillon
• Proceedings of the National Academy of Sciences…
• 2013

From job interviews to the heat of battle, it is evident that people think and learn differently when stressed. In fact, learning under stress may have long-term consequences; stress facilitates… (More)

Interaction of threat and verbal working memory in adolescents.

• Nilam H. Patel, Katherine Vytal, +4 authors Monique Ernst
• Psychophysiology
• 2016

Threat induces a state of sustained anxiety that can disrupt cognitive processing, and, reciprocally, cognitive processing can modulate an anxiety response to threat. These effects depend on the… (More)

Towards a mechanistic understanding of pathological anxiety: the dorsal medial prefrontal-amygdala 'aversive amplification' circuit in unmedicated generalized and social anxiety disorders.

• Oliver J. Robinson, Marissa Krimsky, Lynne Lieberman, Phillip S Allen, Katherine Vytal, Christian Grillon
• The lancet. Psychiatry
• 2014

BACKGROUND We have delineated, across four prior studies, the role of positive dorsal medial prefrontal/anterior cingulate cortex (dmPFC/ACC)-amygdala circuit coupling during aversive processing in… (More)
