Effect of Thirst on the Acoustic Startle Reflex
Psychological Reports, 1985Eight rats were tested for acoustic startle, using a within-subjects design, while they were under either 0 or 21 hr. water deprivation. The startle stimulus was a percussive, non-tonal sound. No significant effect of thirst on startle was found.

The acoustic startle reflex in ischemic stroke
Neurology, 2004The authors recorded the acoustic startle response in 32 patients with stroke, 6 patients with incomplete cervical cord lesions, and 26 controls. Increased startle occurred in about one quarter of both stroke and spinal cord injury patients. The response in biceps demonstrated the greatest deviation from normal, with less marked changes in tibialis ...

Biomedical Radioelectronics
Observation and registration of the behavior of laboratory animals in response to a sound stimulus (Acoustic Startle Reflex - ASR) is one of the methods of experimental physiological research. The manifestation of this reflex is a startle - a rapid muscle twitching caused by a sudden and intense acoustic signal.

AUDIOGENIC STARTLE REFLEX OF MAN AND ITS RELATIONSHIP TO STARTLE SYNDROMES
Brain, 1986The normal human audiogenic startle reflex is defined from a review of the literature, substantiated by a current investigation of normal subjects, and clarified pathophysiologically by a discussion of animal experimentation. The basic information is used to evaluate critically a variety of syndromes loosely termed 'startle' in the past.

Emotion, attention, and the startle reflex.
Psychological Review, 1990This theoretical model of emotion is based on research using the startle-probe methodology. It explains inconsistencies in probe studies of attention and fear conditioning and provides a new approach to emotional perception, imagery, and memory. Emotions are organized biphasically, as appetitive or aversive (defensive).

Modulation of the startle reflex by pleasant and unpleasant music
International Journal of Psychophysiology, 2009The issue of emotional feelings to music is the object of a classic debate in music psychology. Emotivists argue that emotions are really felt in response to music, whereas cognitivists believe that music is only representative of emotions. Psychophysiological recordings of emotional feelings to music might help to resolve the debate, but past studies ...

Effects of ethanol on the acoustic startle reflex in humans
Psychopharmacology, 1994The effect of ethanol on human sensorimotor reactivity was assessed by examining the acoustic startle response. Twelve healthy normal subjects participated in a startle reflex experiment in which placebo or ethanol were given on separate days. Three types of startle probes were used.

Attention and schizophrenia: Impaired modulation of the startle reflex.
Journal of Abnormal Psychology, 1993The startle reflex (SR) elicited by abrupt stimuli can be modified by attention to nonstartling stimuli that shortly precede the startle-eliciting stimulus. The present study of 15 recent-onset, relatively asymptomatic schizophrenic outpatients and 14 demographically matched normal control subjects demonstrated that attentional modulation of SR is ...

Habituation of the startle reflex in rats with septal lesions
Behavioral Biology, 1974The habituation rate of the startle reflex in rats with sep tat lesions was compared to the rate in control rats when pairs of septal and control rats were matched according to the initial response amplitude. The lesions were mainly restricted to the dorsal part of the septal nuclei.

Psychopharmacology, 2002
IntroductionA large body of experimental literature indicates that the startle reflex is a sensitive measure of fear and anxiety. In both humans and animals, the startlereflex is increased when the startle-eliciting stimulus is presented in the presence of a cue that signals an aversive event, such as a shock (Davis andAstrachan 1978; Grillon et al ...
