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 ...

Conditioned increase of locomotor activity induced by haloperidol
(PLOS, 2018)
Dopamine antagonist drugs have profound effects on locomotor activity. In particular, the administration of the D2 antagonist haloperidol produces a state that is similar to catalepsy. In order to confirm whether the ...

Disentangling the effects of context change and context familiarity on Latent Inhibition with a Conditioned Taste Aversion procedure
(Elsevier, 2013)
Contextual specificity of Latent Inhibition (LI) has been demonstrated using an ample range of experimental procedures. Context dependence has not been consistently obtained, however, when LI has been induced using a ...

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 ...

Reward devaluation disrupts latent inhibition in fear conditioning
(Springer US, 2018)
Three experiments explored the link between reward shifts and latent inhibition (LI). Using consummatory procedures, rewards were either downshifted from 32% to 4% sucrose (Experiments 1–2), or upshifted from 4% to 32% ...

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 ...
