Generalization of Fear-potentiated Startle in the Presence of Auditory Cues: A Parametric Analysis [PDF]
Intense fear responses observed in trauma-, stressor-, and anxiety-related disorders can be elicited by a wide range of stimuli similar to those that were present during the traumatic event. The present study investigated the experimental utility of fear-

Beyond Extinction: Prolonged Conditioning and Repeated Threat Exposure Abolish Contextual Renewal of Fear-Potentiated Startle Discrimination but Leave Expectancy Ratings Intact [PDF]
Extinction treatments decrease fear via repeated exposures to the conditioned stimulus (CS) and are associated with a return of fear. Alternatively, fear can be reduced via reductions in the perceived intensity of the unconditioned stimulus (US), e.g ...

Prospective Associations between Emotion Dysregulation and Fear-Potentiated Startle: The Moderating Effect of Respiratory Sinus Arrhythmia [PDF]
Background: Emotion dysregulation has been implicated in the negative outcomes following trauma exposure. A proposed biomarker of emotion dysregulation, respiratory sinus arrhythmia (RSA), has demonstrated associations with trauma-related phenomena, such

No impact of deep brain stimulation on fear-potentiated startle in obsessive-compulsive disorder [PDF]
Deep brain stimulation (DBS) of the ventral internal capsule is effective in treating therapy refractory obsessive-compulsive disorder (OCD). Given the close proximity of the stimulation site to the stria terminalis (BNST), we hypothesized that the ...

The effects of spaced versus massed extinction training on extinction retention of conditioned fear learning in male rats [PDF]
IntroductionExtinction learning of conditioned fear behavior has been used as a translational model to study human fear-, anxiety-, trauma-, and stressor-related disorders and their underlying neurobiology in animal models because the underlying neural ...

The role of fear learning in the development of psychosis: an EEG study utilizing a differential fear conditioning paradigm in people with psychotic vulnerability [PDF]
By studying how individuals in an “at-risk” state of psychosis learn about threat and safety cues – specifically, how they develop and unlearn fear responses to neutral cues – we might better understand the mechanisms leading to heightened arousal and ...

Characterizing the Prevalence of Psychiatric Conditions and Fear-Potentiated Startle Response in Civilians with a History of Trauma and Seizures [PDF]
Background Depression, posttraumatic stress disorder (PTSD), and suicidality are more prevalent among people with seizures, but few studies exist in low-resourced minoritized populations.

Anxiety, fear extinction, and threat-related amygdala reactivity in children exposed to urban trauma
Introduction Childhood trauma is strongly associated with fear-related psychopathology, like anxiety and posttraumatic stress disorder (PTSD). Atypical fear extinction and neural responses to social threat (i.e., negative emotional faces) may serve as ...
