Example Sentences:
(1) These later results suggest that dopamine agonists increase sensorimotor reactivity measured with acoustic startle by acting on sensory rather than motor parts of the reflex arc.
(2) The hypothesis that the standard acoustic startle habituation paradigm contains the elements of Pavlovian fear conditioning was tested.
(3) But that promise was beginning to startle the markets, which admire Monti’s appetite for austerity and fear the free spending and anti-European views of some Italian politicians.
(4) Both startle amplitude and onset latency showed significantly greater facilitation in the preschool children than in the 8-year-olds and adults.
(5) flexion, stretch, rolling, startle, jumping (stepping), and writhing.
(6) Three response patterns were scored: (1) no startle, (2) startle without response decrement, and (3) response decrement by 12 stimuli.
(7) More importantly, motor and cardiovascular responses to startle may be separated through discrimination of afferent stimuli suggesting either differences in neural pathways for acoustic and tactile stimuli or a differential dependency of the various responses on stimulus characteristics.
(8) The startle-elicited increase in blood pressure was significantly elevated in SHRs and at the same time the acoustic startle response was depressed as compared to WKY rats.
(9) A placebo effect could not definitely be ruled out, but the startling changes seen in patients who had been followed for years with other forms of therapy suggest strongly that this improvement was genuine.
(10) In general, conditions that affect the amplitude of the acoustic startle reflex similarly influence the disruptive effect of a noise burst on motor performance, but the two measures are not correlated in the detail necessary to suggest a causative relationship.
(11) The results are compared to other drugs known to affect the startle reflex.
(12) In awake rats the latency of auditory startle recorded electromyographically in the neck is about 5 ms, suggesting that the primary component of this brainstem reflex is mediated by a neural circuit with only a few synapses.
(13) A series of seven experiments related amplitude and latency of the pigeon's startle response, elicited by an intense visual stimulus, to antecedent auditory and visual events in the sensory environment.
(14) The acoustic startle response (ASR) of male rats was measured during several sessions over a 24-hr period in both a light-dark cycle and a constant-dark condition.

(18) In the present work no significant differences were found between the behaviour of FG7142-kindled rats and vehicle-treated controls in social interaction test, elevated plus maze, or the Vogel conflict test of anxiety or in tests of home cage aggression or startle responses.
(19) The first attempted to determine a sonic boom level below which startle would not occurr.
(20) It is able to (1) sample startle responses from 5 animals simultaneously during a specific time band after the eliciting stimulus; (2) convert the analogue startle amplitudes into 2-digit numbers; (3) print the digital results of each startle in each animal; (4) add up the startle amplitudes for each rat over a preset number of stimuli and print the totals; (5) print the interstimulus interval and (6) code for up to six diferent types of trials.
