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) experiments where a translational method of anxiety induction (risk of shock) has been shown to disrupt spatial and verbal WM performance. Performance declines when resources (e.g., spatial attention, execut...

The fear of arousal sensations characterizes some anxiety disorders and is a core feature of an established risk factor for anxiety and related disorders (i.e. anxiety sensitivity; Taylor, 1999). Anxiety sensitivity (AS) refers to a fear of anxiety-related bodily sensations stemming from beliefs that these have catastrophic consequences. Interoceptive exposure (IE; repeated exposure to feared a...

Background There is increasing evidence suggesting that the Locus Coeruleus plays a role in pain-related anxiety. Indeed, we previously found that prolonged arthritis produces anxiety-like behavior in rats, along with enhanced expression of phosphorylated extracellular signal-regulated kinase 1/2 (a marker of plasticity) in the Locus Coeruleus. However, it is unknown how this effect correlates ...

patients and methods sixty children aged between 2 and 12 years, and scheduled for on-pump surgery due to a congenital heart disease were randomly assigned into two groups. oral midazolam (0.5 mg/kg up to 15 mg per patient) and dexmedetomidine (2 µg/kg) were administered 45 minutes pre-anesthesia. children’s anxiety, mask acceptance behavior, hemodynamic measures, and cardiopulmonary outcomes w...

The inhibitor of monoaminooxydase isatin and the ligand of B-receptors cholecystokinin-4 play a significant role in the suppression and induction of depressive and anxiety states. We induced the formation of auto-antibodies to these compounds against their conjugates with antigen-carrier by immunization of white rats. The result was long-term (more than 2 months) stimulation of depressive and a...

The rapid progress in knee implants technology and operational techniques go together with more and more modem medical programs, designed to optimize the patients' care and shorten their stay in hospital. However, this does not guarantee any elimination ofperioperative stress in patients. Anxiety is a negative emotional state arising from stressful circumstances accompanied by activation of the...

Imagine you are being gazed at by multiple individuals simultaneously. Is the provoked anxiety a learned social-specific response or related to a pathological disorder known as trypophobia? A previous study revealed that spectral properties of images induced aversive reactions in observers with trypophobia. However, it is not clear whether individual differences such as social anxiety traits ar...

Is the provoked anxiety a 2 learned social-specific response or related to a hole-specific pathological disorder known as 3 trypophobia? A previous study revealed that spectral properties of images induced aversive 4 reactions in observers with trypophobia. However, it is not clear whether individual differences 5 such as ...

Tetratricopeptide repeat domain 9A (TTC9A) expression is abundantly expressed in the brain. Previous studies in TTC9A knockout (TTC9A-/-) mice have indicated that TTC9A negatively regulates the action of estrogen. In this study we investigated the role of TTC9A on anxiety-like behavior through its functional interaction with estrogen using the TTC9A-/- mice model. A battery of tests on anxiety-...
