Intolerance of uncertainty predicts fear extinction in amygdala-ventromedial prefrontal cortical circuitry

Jayne Morriss, Anastasia Christakou, Carien M. van Reekum
2015 Biology of Mood & Anxiety Disorders

A translational bridge between mouse and human models of learned safety

Daniela D. Pollak, Michael T. Rogan, Tobias Egner, David L. Perez, Ted K. Yanagihara, Joy Hirsch
2010 Annals of Medicine  
We present a translational bridge between mouse and human models of learned safety in which cellular and molecular insights from animal experiments are extended to the human neural circuitry.  ...  Learned safety is established by negatively correlating the occurrence of a neutral stimulus and a noxious stimulus, which renders the previously neutral stimulus a 'safety signal'.  ...  Pollak Declaration of interest: The authors report no biomedical fi nancial interests or other confl icts of interest.  ...

Reappraising fear: is up-regulation more efficient than down-regulation?

Julian Wiemer, Milena M. Rauner, Yannik Stegmann, Paul Pauli
2021 Motivation and Emotion  
Valence and arousal ratings indicated successful up- and down-regulation of the emotional experience, while heart rate and pupil dilation increased during up-regulation, but showed no reduction in down-regulation  ...  State and trait anxiety correlated with evaluations of safety but not threat stimuli, which supports the role of deficient safety learning in anxiety. Reappraisal did not modulate this effect.  ...  Acknowledgements We acknowledge the assistance of Maria A. M. Hoffmann in preparing the manuscript. Funding Open Access funding enabled and organized by Projekt DEAL.  ...

A pupil size response model to assess fear learning

Christoph W. Korn, Matthias Staib, Athina Tzovara, Giuseppe Castegnetti, Dominik R. Bach
2016 Psychophysiology  
Current approaches to assess fear learning from pupil responses rely on ad hoc specifications.  ...  Finally, we used our previously developed luminance-related pupil responses to infer the timing of the likely neural input into the pupillary system.  ...  Fear learning, in this approach, is quantified by the amplitude of a cognitive input into the pupil system.  ...

During the dichotic listening task, presentation of fear-conditioned stimuli reinstated the acquired fear response, as reflected in pupil and EEG alpha-beta-band responses.  ...  Critically, pupil dilation to CS+ was correlated with stronger EEG alpha-beta desynchronization, suggesting a common dependence on NE release.

2021 International Journal of Psychophysiology  
We present a single case who can change pupil size on command with dilation of pupil diameter of around 0.8 mm, and constriction of around 2.4 mm.  ...  It still remains open where these neural signals enter the final pathway, either innervating the pupil's dilator directly, or more indirectly by inhibiting the parasympathetically innervated antagonistic  ...  We would like to thank Sascha Malz for his great support running the optometric testing of the participant.  ...
