RATIONALE Although 5-HT2 receptors seem to play an important role in anxiety, results from numerous studies are still highly variable. Moreover, little is known about the behavioral effects of centrally administered 5-HT2 compounds in animal models of anxiety. OBJECTIVE The current study was performed to: (1) further investigate the effects of 5-HT2(More)
Recent years have seen growing interest in the development of genetic animal models to investigate the bidirectional relationship between trait anxiety and defensive reactions. The present study further analyzed behavioral correlates of two novel breeding lines of rats, Carioca high-and low-conditioned freezing (CHF and CLF), based on defensive freezing(More)
Intra-aortic balloon pump (IABP) is commonly used as mechanical support after cardiac surgery or cardiac shock. Although its benefits for cardiac function have been well documented, its effects on cerebral circulation are still controversial. We hypothesized that transfer function analysis (TFA) and continuous estimates of dynamic cerebral autoregulation(More)
