Dopamine D2-like receptors modulate unconditioned fear: role of the inferior colliculus. [PDF]
PLoS ONE, 2014 BACKGROUND: A reduction of dopamine release or D2 receptor blockade in the terminal fields of the mesolimbic system clearly reduces conditioned fear.

Blood pressure variations real-time reflect the conditioned fear learning and memory. [PDF]
PLoS ONE, 2012 The conditioned fear learning and memory occurs when a neutral conditioned stimulus (CS) is paired with an aversive unconditioned stimulus (US). This process is critically dependent on the amygdala and inevitably involves blood pressure (BP) alterations.

Conditioned fear extinction and reinstatement in a human fear-potentiated startle paradigm [PDF]
Learning & Memory, 2006 The purpose of this study was to analyze fear extinction and reinstatement in humans using fear-potentiated startle. Participants were fear conditioned using a simple discrimination procedure with colored lights as the conditioned stimuli (CSs) and an airblast to the throat as the unconditioned stimulus (US).

Expression of freezing and fear‐potentiated startle during sustained fear in mice [PDF]
Genes, Brain and Behavior, 2015 Fear‐potentiated acoustic startle paradigms have been used to investigate phasic and sustained components of conditioned fear in rats and humans. This study describes a novel training protocol to assess phasic and sustained fear in freely behaving C57BL/6J mice, using freezing and/or fear‐potentiated startle as measures of fear, thereby, if needed ...

Predicting Fear Extinction in Posttraumatic Stress Disorder
Brain Sciences, 2023 Fear extinction is the basis of exposure therapies for posttraumatic stress disorder (PTSD), but half of patients do not improve. Predicting fear extinction in individuals with PTSD may inform personalized exposure therapy development.

Stress Resilience Assessment Based on Physiological Features in Selection of Air Traffic Controllers
IEEE Access, 2019 Stress resilience is recognized as an important occupational prerequisite for air traffic controllers (ATCs). A system for input/output multimodal stress resilience assessment based on physiological features has been developed and applied in the ATC ...

Loop diuretics have anxiolytic effects in rat models of conditioned anxiety. [PDF]
PLoS ONE, 2012 A number of antiepileptic medications that modulate GABA(A) mediated synaptic transmission are anxiolytic. The loop diuretics furosemide (Lasix) and bumetanide (Bumex) are thought to have antiepileptic properties.
