Whole-Body Prepulse Inhibition Protocol to Test Sensorymotor Gating Mechanisms in Monkeys
Prepulse inhibition (PPI) is the decrease of startle reflex amplitude when a slight stimulus is previously generated. This paradigm may provide valuable information about sensorimotor gating functionality. Here we aimed at determining the inhibited and uninhibited startle response of capuchin monkeys (Sapajus spp.), and to evaluate the role of the superior colliculus in PPI. Capuchin monkeys we...
متن کاملSensorimotor gating and anxiety: prepulse inhibition following acute exercise.
This investigation examined whether gating related deficits among individuals with high trait anxiety could be moderated by an acute bout of exercise. Low (LA) and high (HA) trait anxious participants engaged in either a quiet rest or an exercise session on separate occasions. Replicating previous findings, HA participants exhibited significantly reduced PPI at lead intervals of 30 and 60 ms re...
متن کاملIn Silico Whole Genome Association Scan for Murine Prepulse Inhibition
BACKGROUND The complex trait of prepulse inhibition (PPI) is a sensory gating measure related to schizophrenia and can be measured in mice. Large-scale public repositories of inbred mouse strain genotypes and phenotypes such as PPI can be used to detect Quantitative Trait Loci (QTLs) in silico. However, the method has been criticized for issues including insufficient number of strains, not cont...
متن کاملSensory gating in rats: lack of correlation between auditory evoked potential gating and prepulse inhibition.
This study was designed to evaluate the possible similarities between two paradigms designed to measure sensory gating: (1) an auditory evoked potential (AEP), called the P50 gating paradigm; and (2) an acoustic startle (ASR), called the prepulse inhibition paradigm. These paradigms show a number of methodological, pharmacological, and neurobiological similarities, and they are both disturbed i...
متن کاملPrepulse-elicited startle in prepulse inhibition.
BACKGROUND Prepulse inhibition (PPI) has become a major experimental paradigm in the study of psychiatric disorders. In this study, a potential confound in measurement and interpretation of PPI, namely startle reactions to so-called "nonstartling" prepulses, was examined. METHODS Prepulses of 80, 85, and 90 dB(A) were presented on their own or followed by a pulse of 115 dB(A) (lead interval: ...
