In this thesis, three studies investigating the impact of stress on the protective startle eye blink reflex are reported. In the first study a decrease in prepulse inhibition of the startle reflex was observed after intravenous low dose cortisol application. In the second study a decrease in reflex magnitude of the startle reflex was observed after pharmacological suppression of endogenous cortisol production. In the third study, a higher reflex magnitude of the startle reflex was observed at reduced arterial and central venous blood pressure. These results can be interpreted in terms of an adaption to hostile environments.
