ASSESSMENT OF NEUROTENSIN RECEPTOR AGONIST EFFECTS ON FEAR-POTENTIATED STARTLE
… in both male and female C57BL/J6 mice using the fear-potentiated startle (FPS) paradigm. Startle chambers were equipped with a shock-grid floor, fluorescent light, and an acoustic startle speaker. Conditioning took place between the light and floor shock, and test sessions measured startle to a …

5,7-dihydroxytryptamine lesions of the rat amygdala increase learned fear behavior.
… of the amygdala (LA) plays a key role in learned fear and anxiety, while dysfunctional LA circuitry is implicated in fear and anxiety psychopathologies. The LA is under inhibitory modulation and prone to hyperexcitation with inhibitory release. This hyperexcitation can result in enhanced fear and …

Prenatal stress alters fear-conditioned behaviors and the response to serotonergic drugs
… stressed (PS) rats, most notably the acoustic startle response and behavioral inhibition (i.e. freezing). PS rats do not differ in baseline peak startle responding, or in the habituation of the peak startle response when compared to the non-prenatally stressed (CON) rats. However, PS rats have …

A move towards studying both pavlovian & instrumental contributions to conditioning abnormalities in the anxiety disorders
Fear-conditioning experiments in clinical anxiety have focused almost exclusively on passive- emotional, Pavlovian conditioning, rather than active-behavioral, instrumental conditioning. Paradigms capable of eliciting both Pavlovian and instrumental conditioning are thus needed to experimentally …

Attention-Emotion Interactions in Psychopathy
… traits. Event-related brain potentials and startle reflex magnitude were collected while participants heard blink eliciting noise probes and viewed unpleasant and neutral pictures matched on visual complexity from the International Affective Picture System (Lang et al., 2005). These …
