The effects of memantine on prepulse inhibition. [PDF]

open access: yes, 2009
Reduced prepulse inhibition (PPI) of startle provides evidence of deficient sensorimotor gating in several disorders, including schizophrenia. The role of NMDA neurotransmission in the regulation of PPI is unclear, due to cross-species differences in the

The startle reflex as an indicator of psychopathic personality from childhood to adulthood: A systematic review

open access: yesActa Psychologica, 2021
The startle reflex has been suggested to operate as a psychophysiological marker of psychopathic personality, based on findings from studies using a range of different methodologies and participant samples.

Startle-triggered responses indicate reticulospinal drive is larger for voluntary shoulder versus finger movements

open access: yesScientific Reports, 2023
Recent primate studies have implicated a substantial role of reticulospinal pathways in the production of various voluntary movements. A novel way to assess the relative reticulospinal contributions in humans is through the use of a “StartReact” paradigm

Psychophysiological correlates of peritraumatic dissociative responses in survivors of life-threatening cardiac events [PDF]

open access: yes, 2002
The psychophysiological startle response pattern associated with peritraumatic dissociation (DISS) was studied in 103 survivors of a life-threatening cardiac event (mean age 61.0 years, SD 13.95).

Removal of GABAA receptor γ2 subunits from parvalbumin neurons causes wide-ranging behavioral alterations [PDF]

open access: yes, 2011
We investigated the behavioral significance of fast synaptic inhibition by αβγ2-type GABA(A) receptors on parvalbumin (Pv) cells. The GABA(A) receptor γ2 subunit gene was selectively inactivated in Pv-positive neurons by Cre/loxP recombination.

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,

Emotion ownership: different effects on explicit ratings and implicit responses [PDF]

open access: yes, 2013
This study is based on the idea that emotion-related processing happens on various different levels. Common methods that are used to measure different aspects of emotion-related processing exhibit specific sensitivities to one or the other of these ...

Targeting the Stress System During Gestation: Is Early Handling a Protective Strategy for the Offspring? [PDF]

open access: yes, 2020
The perinatal window is a critical developmental time when abnormal gestational stimuli may alter the development of the stress system that, in turn, influences behavioral and physiological responses in the newborns.

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]

open access: yes, 2013
Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that
