The observed downward recruitment of muscles responses further support the idea that startle
reflex forms part of the neuromuscular responses to a rear-end collision.
2008), we used a set of cues-pictures pairings as learning (non-probed) trials during the first half of the task, followed by a second set of pairings where auditory probes were delivered to examine the effects of emotional valence and arousal over anticipatory startle
reflex modulation--likewise prior investigation focused on anticipation of affective material.
Initially, twelve stimulus presentations were required to produce habituation of the startle
reflex; to produce habituation of the startle
reflex that had undergone apparent spontaneous recovery, only six stimulus presentations were required.
Pynoos said to meeting attendees, "If I give you a second startle
noise right after the first, your response will be greatly inhibited.
Fast and Singular Muscle Responses Initiate the Startle
Response of Pantodon buchholzi (Osteoglossomorpha).
The data of one subject were unavailable for startle
blink reflex (n = 44), heart-rate data of one subject were discarded from statistical analysis due to intractable recording artifacts (n = 44), and SCR data of one subject were discarded due to a low rate of responses (< 2; n = 44).
The researchers concluded that the mirror neuron system is involved in emotional processing since the startle
reflex was modulated by primes of emotionally congruent biological motion.
Across a variety of studies we see big startle
differences in people with PTSD versus those who don't have the disorder," Dr.
Ritzmann, a Case Western Reserve neurobiologist who studies startle
response and works with Beer on this project.
According to David Johnson, general manager at startle
online, the company went through an extensive tender process with the leading suppliers before selecting Informix's Media360 media asset management solution.
probe was presented during the cue and during the postcue recovery period as investigators measured the fear-potentiated startle
response--increases in electromyographic signals from the eyeblink reflex.
Psychopaths show decreased startle
responses compared with nonpsychopaths when viewing aversive photographs, Edward M.
