Heritability of acoustic startle magnitude, prepulse inhibition, and startle latency in schizophrenia and control families.
Prepulse inhibition (PPI) is an acoustic startle paradigm that has been used as an operational measure of sensorimotor gating. Many patients with schizophrenia have impaired PPI, and several lines of evidence suggest that PPI may represent a heritable endophenotype in this disease. We examined startle magnitude and latencies in 40 schizophrenia patients, 58 first-degree relatives of these patie...
متن کاملStartle disorders of man: hyperekplexia, jumping and startle epilepsy.
Startle is a basic alerting reaction common to all mammals. A rapid reflex not amenable to voluntary control, it was studied extensively by Strauss in 1929 [1], and is the subject of a monograph by Landis and Hunt [2] and a more recent study by Gogan [3]. In the human adult, except for minor interpersonal variations, a stereotyped motor pattern is seen consisting of eye blinking facial grimacin...
متن کاملAnger and cardiovascular startle reactivity in normotensive young males.
Anger has been implicated in the etiology of hypertensive disease. Trait anger has been linked to enhanced cardiovascular responsiveness. However, whether this association reflects differences in context appraisal or a general hyper-reactivity of the cardiovascular system remains unclear. We studied the cardiovascular response to acoustic startle probes in 76 healthy Caucasian males in differen...
متن کاملStartle cue-reactivity differentiates between light and heavy smokers.
AIMS It was assumed that the startle amplitude in smokers is reduced while viewing pictures of smoking, suggesting that smoking cues are appetitive. The goal of the present study was to investigate (i) whether smoking scenes induce appetitive cue effects in smokers, and (ii) whether smoking intensity is related to cue-reactivity. DESIGN Smokers and non-smokers participated in a single session...
متن کاملPhysiological reactivity of pregnant women to evoked fetal startle.
OBJECTIVE The bidirectional nature of mother-child interaction is widely acknowledged during infancy and childhood. Prevailing models during pregnancy focus on unidirectional influences exerted by the pregnant woman on the developing fetus. Prior work has indicated that the fetus also affects the pregnant woman. Our objective was to determine whether a maternal psychophysiological response to s...
