Modulation of the startle reflex by pleasant and unpleasant music

International Journal of Psychophysiology, 2009
The 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, 1994
The 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, 1993
The 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, 1974
The 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.

Startle and blink reflex in high functioning autism

Neurophysiologie Clinique/Clinical Neurophysiology, 2016
An important clinical feature of autism is the presence of atypical responses to sensory stimuli. In this study, we investigated if high functioning autistic patients had abnormalities in the blink reflex and the startle reaction to auditory or somatosensory stimuli. Fourteen patients aged between 7 and 16 years were included in the study.

Emotion, novelty, and the startle reflex: Habituation in humans.

Behavioral Neuroscience, 1993
Previous research with both animal and human subjects has shown that startle reflex magnitude is potentiated in an aversive stimulus context, relative to responses elicited in a neutral or appetitive context. In the present experiment, the same pleasant, unpleasant, and neutral picture stimuli were repeatedly presented to human subjects. Startle reflex

MORO REFLEX AND STARTLE PATTERN

Archives of Neurology And Psychiatry, 1938
The Moro reflex, reported by Moro 1 in 1918, is a complex response in which the arms are extended at the sides to approximate an arch and then slowly brought together one over the other in front of the body. The legs execute a similar movement. It is found only in very young infants and has usually disappeared by the end of the fourth month.

Caffeine and prepulse inhibition of the acoustic startle reflex

Psychopharmacology, 1999
A stimulus presented immediately prior to a startle reflex-eliciting stimulus inhibits the startle reflex. This is termed prepulse inhibition (PPI) and is postulated to index automatic and controlled attentional processing of the prepulse.Two experiments investigated the effect of 0, 2, and 4 mg/kg oral caffeine on PPI of the acoustic startle eyeblink ...

Winter is coming: Seasonality and the acoustic startle reflex

Physiology & Behavior, 2017
Circannual rhythms and seasonality have long been in the interest of research. In humans, seasonal changes in mood have been extensively investigated since a substantial part of the population experiences worsening of mood during winter. Questions remain regarding accompanying physiological phenomena.

Accelerometric startle reflex detector

Biomedical Radioelectronics
Problem statement. The innate reflex of startling in response to a short unexpected sound stimulus (acoustic startle reflex – ASR) is characteristic of both experimental animals and humans. Among the ASR parameters, the amplitude of muscle contraction in response to a strong stimulus and the degree of its suppression by a previous weak stimulus ...
