Neural substrates of fear conditioning, extinction, and spontaneous recovery in passive avoidance learning: a c-fos study in rats.
Extinguishing fear conditioning and preventing the return of fear are the goal in the treatment of anxiety disorders. However, the neural substrates that mediate fear conditioning, extinction, and spontaneous recovery (i.e., the return of fear) remain uncertain. We utilized the aversive passive avoidance learning paradigm and Fos-like immunoreactivity to elucidate this issue. Exception for naïv...
متن کاملIs "fear of passive movement" a distinctive component of the Fear-Avoidance Model in whiplash?
OBJECTIVES Modify the Tampa Scale for Kinesiophobia (TSK) for 'fear of passive motion' beliefs. METHODS With permission, a 14-item modification, the TSK-PM (passive movement), was created. Test-retest reliability was tested first. Construct validity was tested in chronic whiplash patients by comparing the TSK-PM with the TSK, the Neck Disability Index (NDI) and cervical ranges of motion. RE...
متن کاملThe amygdala modulates memory consolidation of fear-motivated inhibitory avoidance learning but not classical fear conditioning.
Although the lateral and basal nuclei of the amygdala are believed to be essential for the acquisition of Pavlovian fear conditioning, studies using post-training manipulations of the amygdala in the inhibitory avoidance learning paradigm have recently called this view into question. We used the GABA(A) agonist muscimol to functionally inactivate these nuclei immediately after single-trial Pavl...
متن کاملAnterograde effects of a single electroconvulsive shock on inhibitory avoidance and on cued fear conditioning.
A single electroconvulsive shock (ECS) or a sham ECS was administered to male 3-4-month-old Wistar rats 1, 2, and 4 h before training in an inhibitory avoidance test and in cued classical fear conditioning (measured by means of freezing time in a new environment). ECS impaired inhibitory avoidance at all times and, at 1 or 2 h before training, reduced freezing time before and after re-presentat...
متن کاملTraining discrimination diminishes maladaptive avoidance of innocuous stimuli in a fear conditioning paradigm
Anxiety disorders are the most common mental disorder worldwide. Although anxiety disorders differ in the nature of feared objects or situations, they share a common mechanism by which fear generalizes to related but innocuous objects, eliciting avoidance of objects and situations that pose no objective risk. This overgeneralization appears to be a crucial mechanism in the persistence of anxiet...
