Locus coeruleus neuromodulation of memories encoded during negative or unexpected action outcomes.
When people experience surprising or sub-optimal performance outcomes, an increase in autonomic arousal helps allocate cognitive resources to adjust behavior accordingly. The locus-coeruleus-norepinephrine (LC-NE) system regulates a central orienting response to behaviorally relevant events, and might therefore signal the need to attend to and learn from performance feedback. Memories of such e...
متن کاملThe role of left and right Locus Coeruleus in formalin test in rats
Introduction: Pain as a complex process in the CNS has been extensively studied by many researchers. It has been found that pain is controlled by certain pathways in the CNS, one of most important of which is the descending noradrenergic system. The pathway begins with Locus Coeruleus (LC) nucleus and ends in the spinal cord. In this study, formalin test was used as a chemical and tonic pain...
متن کاملOrganization of the Locus Coeruleus-Norepinephrine System
The release of the neurotransmitter norepinephrine throughout the mammalian brain is important for modulating attention, arousal, and cognition during many behaviors. Furthermore, disruption of norepinephrine-mediated signaling is strongly associated with several psychiatric and neurodegenerative disorders in humans, emphasizing the clinical importance of this system. Most of the norepinephrine...
متن کاملEffects of bilateral lesion of the locus coeruleus on the sleep-wake cycle in the rat
Introduction: Noradrenergic cells in LC participate in the process of cortical activation and behavioral arousal. The evidence suggests that locus ceoruleus (LC) plays an important role in the sleep-wake cycle. The aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the LC. Materials and Methods: Male Wistar rats we...
متن کاملThe role of locus coeruleus nucleus TRPV1 receptors in the development and expression of morphine dependence
Objective(s): This study investigated the role of locus coeruleus (LC) nucleus TRPV1 receptors (TRPV1r) in the expression and development of morphine physical dependence by intra-LC administration of AMG9810 (selective TRPV1r antagonist) in male Wistar rats. Materials and Methods: For assessing the development of morphine dependence, AMG9810 (0.0...
