Second-Order Olfactory-Mediated Fear-Potentiated Startle [PDF]
Learning & Memory, 2002 Recently, we reported that discrete (4-sec) olfactory cues paired with footshock serve as effective conditioned stimuli (CSs) for potentiating the acoustic startle response in rats using the fear-potentiated startle paradigm. Because odors are such salient cues for the rat, and because of the robust olfactory conditioning observed previously, the ...

Modification of Fear Memory by Pharmacological and Behavioural Interventions during Reconsolidation. [PDF]
PLoS ONE, 2016 Dysfunctional fear responses play a central role in many mental disorders. New insights in learning and memory suggest that pharmacological and behavioural interventions during the reconsolidation of reactivated fear memories may increase the efficacy of

Additive effects of threat-of-shock and picture valence on startle reflex modulation. [PDF]
PLoS ONE, 2013 The present study examined the effects of sustained anticipatory anxiety on the affective modulation of the eyeblink startle reflex. Towards this end, pleasant, neutral and unpleasant pictures were presented as a continuous stream during alternating ...

Frontiers in Behavioral Neuroscience, 2012 Recent advances in the field of fear learning have demonstrated that a single reminder exposure prior to extinction training can prevent the return of extinguished fear by disrupting the process of reconsolidation. These findings have however proven hard

Noradrenergic blockade of memory reconsolidation:A failure to reduce conditioned fear responding
Frontiers in Behavioral Neuroscience, 2014 Upon recall, a memory can enter a labile state in which it requires new protein synthesis to restabilize. This two-phased reconsolidation process raises the prospect to directly target excessive fear memory as opposed to the formation of inhibitory ...

Neural substrates of individual differences in human fear learning: evidence from concurrent fMRI, fear-potentiated startle, and US-expectancy data [PDF]
, 2012 To provide insight into individual differences in fear learning, we examined the emotional and cognitive expressions of discriminative fear conditioning in direct relation to its neural substrates.

Contextual control over expression of fear is affected by cortisol
Frontiers in Behavioral Neuroscience, 2012 At the core of anxiety disorders is the inability to use contextual information to modulate behavioral responses to potentially threatening events. Models of the pathogenesis of anxiety disorders incorporate stress and concomitant stress hormones as ...

Secure attachment priming protects against relapse of fear in Young adults
Translational Psychiatry, 2021 Previous studies have shown that activating the attachment system attenuates fear learning. This study aimed to explore whether attachment priming can also impact on fear extinction processes, which underpin the management of anxiety disorders.

Psychopathy and Fear-Potentiated Startle: P-Curving the Evidence
, 2021 The goal of the present study is to assess the evidential value present in published studies hypothesizing an attenuated fear-potentiated startle response among individuals high on interpersonal-affective (Factor 1) psychopathic traits.
