Prepulse inhibition deficit as a transdiagnostic process in neuropsychiatric disorders: A systematic review
(BioMed Central, 2023)
Background Psychopathological research is moving from a specific approach towards transdiagnosis through the analysis of processes that appear transversally to multiple pathologies. A phenomenon disrupted in several ...

Startle response and prepulse inhibition modulation by positive- and negative-induced affect
(Elsevier, 2014)
The startle response, a set of reflex behaviours intended to prepare the organism to face a potentially threatening stimulus, can be modulated by several factors as, for example, changes in affective state, or previous ...

Different effects of unexpected changes in environmental conditions on prepulse inhibition in rats and humans
(Elsevier, 2012)
The reduction of the startle response to an auditory stimulus caused by the presentation of another stimulus of lower intensity closely preceding it, a phenomenon known as prepulse inhibition (PPI), can be modulated by ...

Animal models of maladaptive traits: disorders in sensorimotor gating and attentional quantifiable responses as possible endophenotypes
(Frontiers Media, 2016)
Traditional diagnostic scales are based on a number of symptoms to evaluate and classify mental diseases. In many cases, this process becomes subjective, since the patient must calibrate the magnitude of his/her symptoms ...

Reduced Prepulse Inhibition as a Biomarker of Schizophrenia
(Frontiers, 2016-10-18)
The startle response is composed by a set of reflex behaviors intended to prepare the organism to face a potentially relevant stimulus. This response can be modulated by several factors as, for example, repeated presentations ...

Prepulse inhibition modulation by contextual conditioning of dopaminergic activity
(Elsevier, 2013)
When a neutral stimulus is repeatedly paired with a drug, an association is established between them that can induce two different responses: either an opponent response that counteracts the effect of the drug, or a ...

Effect of stress and attention on startle response and prepulse inhibition
(Elsevier, 2016)
The startle reflex magnitude can be modulated when a weak stimulus is presented before the onset of the startle stimulus, a phenomenon termed prepulse inhibition (PPI). Previous research has demonstrated that emotional ...
Artículo
Stressing out! Effects of acute stress on prepulse inhibition and working memory
(Wiley, 2024)
Prepulse inhibition (PPI) of the startle reflex serves as a pre- cognitive marker of sensorimotor gating, and its deficit may predict cognitive impairments. Startle reflex is modulated by many factors. Among them, ...
