Neural Correlates of Attentional Modulation of Prepulse Inhibition [PDF]
Frontiers in Human Neuroscience, 2021 Prepulse inhibition (PPI) refers to the suppression of the startle reflex when the intense startling stimulus is shortly (20–500 ms) preceded by a weak non-startling stimulus (prepulse).

Short-latency prepulse inhibition of the trigeminal blink reflex [PDF]
Frontiers in NeurosciencePrepulse inhibition (PPI) is a well-established phenomenon wherein a weak sensory stimulus attenuates the startle reflex triggered by a subsequent strong stimulus.

Prepulse Inhibition in Cocaine Addiction and Dual Pathologies [PDF]
Brain Sciences, 2021 Cocaine addiction is frequently associated with different psychiatric disorders, especially schizophrenia and antisocial personality disorder. A small number of studies have used prepulse inhibition (PPI) as a discriminating factor between these ...

Prepulse inhibition predicts subjective hearing in rats [PDF]
Scientific Reports, 2021 Auditory studies in animals benefit from quick and accurate audiometry. The auditory brainstem response (ABR) and prepulse inhibition (PPI) have been widely used for hearing assessment in animals, but how well these assessments predict subjective ...

The Effects of Attention on the Syllable-Induced Prepulse Inhibition of the Startle Reflex and Cortical EEG Responses against Energetic or Informational Masking in Humans [PDF]
Brain Sciences, 2022 Prepulse inhibition (PPI) is the reduction in the acoustic startle reflex (ASR) when the startling stimulus (pulse) is preceded by a weaker, non-starting stimulus.

Effects of Magnitude of Leading Stimulus on Prepulse Inhibition of Auditory Evoked Cerebral Responses: An Exploratory Study [PDF]
Life, 2021 An abrupt change in a sound feature (test stimulus) elicits a specific cerebral response, which is attenuated by a weaker sound feature change (prepulse) preceding the test stimulus.

Assessing the Cntnap2 knockout rat prepulse inhibition deficit through prepulse scaling of the baseline startle response curve [PDF]
Translational Psychiatry, 2023 Many neurodevelopmental disorders, including autism spectrum disorder (ASD), are associated with changes in sensory processing and sensorimotor gating. The acoustic startle response and prepulse inhibition (PPI) of startle are widely used translational ...

Looming Effects on Attentional Modulation of Prepulse Inhibition Paradigm [PDF]
Frontiers in Psychology, 2021 In a hazardous environment, it is fundamentally important to successfully evaluate the motion of sounds. Previous studies demonstrated “auditory looming bias” in both macaques and humans, as looming sounds that increased in intensity were processed ...

A Computational Model for the Simulation of Prepulse Inhibition and Its Modulation by Cortical and Subcortical Units [PDF]
Brain SciencesThe sensorimotor gating is a nervous system function that modulates the acoustic startle response (ASR). Prepulse inhibition (PPI) phenomenon is an operational measure of sensorimotor gating, defined as the reduction of ASR when a high intensity sound ...
