1. Virtual reality exposure therapy for spider phobia
Sammanfattning : Exposure therapy for specific phobia involving systematic and repeated presentation of an aversive stimuli or situation is a highly effective treatment for reducing fear and anxiety. Dissemination of this evidence-based treatment has proved challenging, however, and for over 20 years an alternative method of delivery using virtual reality technology has been explored with positive results.

2. Fearful attention : Investigating event-related potentials in spider phobia
Sammanfattning : Previous studies showed that emotional pictures capture attention. Further, this effect was decreased by manipulating spatial attention. In contrast, studies produced mixed findings for effects of perceptual load on attention to emotional pictures. Emotional pictures can be phobic or nonphobic. LÄS MER
3. The Amygdala, Fear and Reconsolidation : Neural and Behavioral Effects of Retrieval-Extinction in Fear Conditioning and Spider Phobia
Sammanfattning : The amygdala is crucially involved in the acquisition and retention of fear memories. Experimental research on fear conditioning has shown that memory retrieval shortly followed by pharmacological manipulations or extinction, thereby interfering with memory reconsolidation, decreases later fear expression.

4. Positron Emission Tomography (PET) Studies in Anxiety Disorders
Sammanfattning : Anxiety disorders are very common and the primary feature is abnormal or inappropriate anxiety. Fear and anxiety is often mediated by the amygdala, a brain structure rich in substance P (SP) and neurokinin 1 (NK1) receptors. LÄS MER
5. The Amygdala, Arousal and Memory: From Lesions to Neuroimaging
Sammanfattning : Emotional events are better remembered than neutral events. But what are the mechanisms behind this memory enhancing effect? It seems that they depend on the arousal level at the moment we experience the event to be remembered. LÄS MER
