Abstract The aim of this research was to investigate the role of brain-behavioral systems, emotional schemas and deficits in executive functioning in prediction of obsessive beliefs in Students. using the correlation method, 152 Undergraduate students of kharazmi University of karaj (81 girl students and 71 boy students) of the age range of 18 to 22 years were selected through available non-...
In this study we provide a comprehensive analysis of the hypothalamic activation pattern during exposure to a live predator or an environment previously associated with a predator. Our results support the view that hypothalamic processing of the actual and the contextual predatory threats share the same circuit, in which the dorsal premammillary nucleus (PMd) plays a pivotal role in amplifying ...
Activity within the social behavior neural network is modulated by the neuropeptide arginine vasotocin (AVT) and its mammalian homologue arginine vasopressin (AVP). However, central AVT/AVP release causes different behavioral effects across species and social environments. These differences may be due to the activation of different neuronal AVT/AVP populations or to similar activity patterns ca...
introduction: Depression is one of the most common psychological disorders that comorbids with substance use disorders. depression is not only the factor that predisposes persons to abuse substanses but also the factor resulting in relapse. The aim of this study was to determine effectiveness of group behavioral activation treatment in reducing depressive symptoms and effects of this treatment ...
Background and purpose: Identifying the nature of social anxiety through its causative factors can provide valuable information for the health system. The purpose of this study was to evaluate a structural model for creating and maintaining factors causing social anxiety disorder in students in a medical sciences university. Materials and methods: A descriptive-correlational study was perform...
The temperamental style of behavioral inhibition has been characterized by exaggerated behavioral and neural responses to cues signaling threat. Virtually no work, however, has addressed whether behavioral inhibition may also confer heightened brain activation in response to positively valenced incentives. We used event-related functional MRI (fMRI) and a monetary incentive delay task to examin...
The activities of many neuronal proteins are modulated by ethanol, but the fundamental mechanisms underlying behavioral effects of ethanol remain unclear. To identify mechanisms responsible for intoxication, we screened for Caenorhabditis elegans mutants with altered behavioral responses to ethanol. We found that slo-1 mutants, which were previously recognized as having slightly uncoordinated m...
Peripheral immune activation can have profound physiological and behavioral effects including induction of fever and sickness behavior. One mechanism through which immune activation or immunomodulation may affect physiology and behavior is via actions on brainstem neuromodulatory systems, such as serotonergic systems. We have found that peripheral immune activation with antigens derived from th...
