Angiotensin AT<sub>1</sub> receptors are implicated in behavioral and physiological processes associated with fear and stress. However, the precise role of AT<sub>1</sub> receptors in modulating fear-related behavior and its relation to their physiological effects remains unclear. Here, we examined innate and learned fear responses and their relationship to cardiovascular arousal in ... Read more >>

Estrogen may be involved in psychosis by an interaction with central dopaminergic activity. Aromatase knockout mice are unable to produce estrogen and have been shown to display altered behavioural responses and effects of the dopamine releaser, amphetamine. This study investigates the effect of gonadal status on amphetamine-induced c-fos expression in ... Read more >>

Prepulse inhibition (PPI) is a measure of sensorimotor gating and an endophenotype of schizophrenia. We have shown previously in rats that estrogen treatment prevents disruption of PPI by the 5-HT(1A)/5-HT(7) receptor agonist 8-hydroxy-2-dipropylaminotetralin (8-OH-DPAT). The aim of the present study was to examine the role of dopamine D(1) and D(2) ... Read more >>
