Modulation of physiological reflexes by pain: role of the locus coeruleus

open access: yesFrontiers in Integrative Neuroscience, 2012
The locus coeruleus is activated by noxious stimuli, and this activation leads to inhibition of perceived pain. As two physiological reflexes, the acoustic startle reflex and the pupillary light reflex, are sensitive to noxious stimuli, this sensitivity,

Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioning

open access: yesBMC Neuroscience, 2011
Background Autonomous reflexes enable animals to respond quickly to potential threats, prevent injury and mediate fight or flight responses. Intense acoustic stimuli with sudden onsets elicit a startle reflex while stimuli of similar intensity but with ...

Hypnotizability, hypnosis and prepulse inhibition of the startle reflex in healthy women: an ERP analysis. [PDF]

open access: yesPLoS ONE, 2013
A working model of the neurophysiology of hypnosis suggests that highly hypnotizable individuals (HHs) have more effective frontal attentional systems implementing control, monitoring performance, and inhibiting unwanted stimuli from conscious awareness,

Habituation of the startle reflex depends on attention in cannabis users

open access: yesBMC Psychology, 2016
Background Cannabis use is associated with an attention-dependent deficit in prepulse inhibition of the startle reflex (PPI). The aim of the current study was to investigate startle habituation in cannabis users and healthy controls during two ...

Slow cortical potential biofeedback and the startle reflex [PDF]

open access: yesBiofeedback and Self-Regulation, 1994
The negativity of slow cortical potentials (SCP) of the surface EEG is a measure of brain excitability, correlating with motor and cognitive preparation. Self-control of SCP positivity has been shown to reduce seizure activity. Following SCP biofeedback from a central EEG electrode position, subjects gained bidirectional control over their SCP.

Interactions between stretch and startle reflexes produce task-appropriate rapid postural reactions

open access: yesFrontiers in Integrative Neuroscience, 2015
Neural pathways underpinning startle reflex and limb stretch reflexes evolved independently and have served vastly different purposes. In their most basic form, the pathways responsible for these reflex responses are relatively simple processing units ...

Quantifying the Acoustic Startle Response in Mice Using Standard Digital Video

open access: yesFrontiers in Behavioral Neuroscience, 2020
The startle response is an unconditional reflex, characterized by the rapid contraction of facial and skeletal muscles, to a sudden and intense startling stimulus.

Shift work-like patterns effect on female and male mouse behavior

open access: yesNeurobiology of Sleep and Circadian Rhythms, 2022
Shift work (work outside of standard daylight hours) is common throughout the Western world. However, there are notable health consequences to shift work, including increased prevalence of mental health and sleep disorders in shift worker populations ...

THE HYPEREKPLEXIAS AND THEIR RELATIONSHIP TO THE NORMAL STARTLE REFLEX

open access: yesBrain, 1991
The startle response to unexpected auditory and somaesthetic stimulation was studied in 8 patients with hereditary or symptomatic hyperekplexia. It was abnormal in its resistance to habituation and in its exaggerated motor response. Both noise and taps to the face and head elicited a normal early blink response, separate from the subsequent true ...

THE EFFECTS OF LEFT VS. RIGHT EAR STIMULATION ON HUMAN STARTLE REFLEX MODULATION [PDF]

open access: yesActa Medica Iranica, 2005
It has been reported previously that modulatory effects of pleasant and unpleasant slides on the human acoustic reflex are observed only if startle probes are presented to the left ear or with binaural presentation. The present study examined the effects
