Significats de acoustic startle en anglès

The acoustic startle response and prepulse inhibition were also unaffected in both strains.

In addition, mutants showed heightened acoustic startle reactivity as well as impaired social discrimination memory.

Testing at graded stimulus intensities indicated an increase in the gain of the acoustic startle reflex.

The surface-recorded electromyographic pattern of audiogenic muscle jerks was identical to that of the normal acoustic startle reflex.

We examined whether the acoustic startle reflex (ASR) was sensitive to lesions induced by focal cerebral ischemia.

Conclusion: With thorough oversight and QA procedures, measures of acoustic startle PPI can be acquired reliably across multiple testing sites.

To test this hypothesis we utilized the acoustic startle reflex, a standard un-conditioned reflex elicited by a sudden loud noise.

The acoustic startle reflex captures activation of these motivational processes and affords a unique measure of reactivity to drug cues.

Rats were tested for acoustic startle and PPI at 3, 5 and 7 weeks postweaning.

Electrical stimulation of peripheral nerves elicited a pattern of generalized muscle jerks that was similar to that of the acoustic startle reflex.

Prepulse inhibition (PPI) of the acoustic startle reflex is an operational measure of sensorimotor gating that is amenable to cross-species comparisons.

Hypothalamic-pituitary-adrenal axis hypofunction, physiologic markers of increased arousal, and increased acoustic startle response are all potential PTSD-associated traits that might be susceptible to genetic analysis.

The results indicate that schizophrenic patients have extensive deficits in both intramodal and cross-modal sensorimotor gating and a trend to show acoustic startle habituation deficits.

Male Wistar rats were tested in acoustic startle sessions in which some startle-eliciting stimuli were presented alone, and others were preceded by a weak prepulse.

Methods: Electromyographic responses to acoustic startle stimuli (pulse alone and prepulse-pulse trials) were recorded in 23 currently abstinent ecstasy users and 20 matched control subjects.

Acoustic startle probes were presented at short and long lead intervals after the onset of tones and occasionally during the intertone interval.
