The brain circuits that create our sense of fear rely on ancient 'hard-wired' components of the limbic system, but also use sensory processing to determine what we become afraid of. A new study shows that, when viewing of simple oriented line stimuli is coupled with aversive experiences, neurons in primary visual cortex rapidly alter their responses in a manner that indicates the line stimuli become a source of fear.

During the last 10 years, a large body of studies have used fear conditioning paradigms to study the role of sleep in the consolidation of fear and safety learning. This line of research could allow u...
Sight is often considered to be the sense most valued by the general public, but there are limited empirical data to support this. This study provides empirical evidence for frequent assertions made b...
During a threatening encounter, people can learn to associate the aversive event with a discrete preceding cue or with the context in which the event took place, corresponding to cue-dependent and con...
Pavlovian fear conditioning paradigms are valuable to investigate fear learning and the return of extinguished fear in the lab. However, their validity is limited, because the aversive stimuli (e.g., ...
Eye-hand span, i.e., the distance between a performer's fixation and execution of a note, has been regarded as a decisive indicator of performers' competence in sight-reading. However, integrated pers...
Since the 2000s, the experiences of children and especially their fear during a consultation, a treatment or examination is food for thought in our establishment. There is no tool validate...
This study investigates whether a one-session exposure treatment for spider-related stimuli can lead to a generalization of extinguished fear to height-related stimuli in individuals with ...
Investigation of the effectiveness and acceptability and usability of a VR height exposure App in individuals with fear of heights.
The current study will investigate the ability of people with and without fear symptoms after trauma to inhibit fear in an experimental situation.
This study aims to test whether aerobic exercise performed after fear extinction learning improves the consolidation and subsequent recall of the learned safety memories (i.e., fear extinc...
Anxiety disorders in which the essential feature is persistent and irrational fear of a specific object, activity, or situation that the individual feels compelled to avoid. The individual recognizes the fear as excessive or unreasonable.
The turning inward of the lines of sight toward each other.
A type of anxiety disorder characterized by unexpected panic attacks that last minutes or, rarely, hours. Panic attacks begin with intense apprehension, fear or terror and, often, a feeling of impending doom. Symptoms experienced during a panic attack include dyspnea or sensations of being smothered; dizziness, loss of balance or faintness; choking sensations; palpitations or accelerated heart rate; shakiness; sweating; nausea or other form of abdominal distress; depersonalization or derealization; paresthesias; hot flashes or chills; chest discomfort or pain; fear of dying and fear of not being in control of oneself or going crazy. Agoraphobia may also develop. Similar to other anxiety disorders, it may be inherited as an autosomal dominant trait.
