Pancreatic polypeptide and its central Y4 receptors are essential for cued fear extinction and permanent suppression of fear
BACKGROUND AND PURPOSE Avoiding danger and finding food are closely related behaviours that are essential for surviving in a natural environment. Growing evidence supports an important role of gut-brain peptides in modulating energy homeostasis and emotional-affective behaviour. For instance, postprandial release of pancreatic polypeptide (PP) reduced food intake and altered stress-induced moto...
متن کاملImpairment in Extinction of Contextual and Cued Fear Following Post-Training Whole-Body Irradiation
Because of the use of radiation in cancer therapy, the risk of nuclear contamination from power plants, military conflicts, and terrorism, there is a compelling scientific and public health interest in the effects of environmental radiation exposure on brain function, in particular hippocampal function and learning and memory. Previous studies have emphasized changes in learning and memory foll...
متن کاملEffects of postretrieval-extinction learning on return of contextually controlled cued fear.
Reactivation of an already consolidated memory makes it labile for a period of several hrs, which are required for its reconsolidation. Evidence suggests that the return of conditioned fear through spontaneous recovery, reinstatement, or renewal can be prevented by blockading this reconsolidation process using pharmacological or behavioral interventions. Postretrieval-extinction learning has be...
متن کاملSleep supports cued fear extinction memory consolidation independent of circadian phase.
Sleep promotes memory, particularly for declarative learning. However, its role in non-declarative, emotional memories is less well understood. Some studies suggest that sleep may influence fear-related memories, and thus may be an important factor determining the outcome of treatments for emotional disorders such as post-traumatic stress disorder. Here, we investigated the effect of sleep depr...
متن کاملThe Class I HDAC inhibitor RGFP963 enhances consolidation of cued fear extinction.
Evidence indicates that broad, nonspecific histone deacetylase (HDAC) inhibition enhances learning and memory, however, the contribution of the various HDACs to specific forms of learning is incompletely understood. Here, we show that the Class I HDAC inhibitor, RGFP963, enhances consolidation of cued fear extinction. However, RGFP966, a strong inhibitor of HDAC3, does not significantly enhance...
