Strain-specific effects of amphetamine on prepulse inhibition and patterns of locomotor behavior in mice.
Several reports describe substantive behavioral differences between strains of mice both at baseline and in response to pharmacological manipulations. For example, mouse strain differences have been reported in prepulse inhibition (PPI) and patterns of locomotor activity, two behavioral processes that are altered by dopamine (DA) agonists such as amphetamine. Here, we characterized acoustic and...
متن کاملEffects of aberrant gamma frequency oscillations on prepulse inhibition.
Emerging literature implicates abnormalities in gamma frequency oscillations in the pathophysiology of schizophrenia, with hypofunction of N-methyl-D-aspartate (NMDA) receptors implicated as a key factor. Prepulse inhibition (PPI) is a behavioural measure of sensorimotor gating, which is disrupted in schizophrenia. We studied relationships between ongoing and sensory-evoked gamma oscillations a...
متن کاملEffects of early acoustic stimulation on prepulse inhibition in mice
The purpose of this study was to determine the effects of an atypical pattern of early acoustic stimulation on auditory development. Previous human research suggests that the acoustic environment of pre-term human infants in the Neonatal Intensive Care Unit (NICU) negatively affects some aspects of auditory development. Animal research suggests that premature auditory stimulation interrupts aud...
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: ...
متن کاملLinking Stress and Schizophrenia: A Focus on Prepulse Inhibition
Schizophrenia affects about 0.5-1.0% of people worldwide, occurring roughly equally in both men and women. The exact causes of schizophrenia are not fully understood, although the consensus of current research is that schizophrenia is a developmental disorder, caused by a genetic liability interacting with environmental and psychosocial stress. However, the possible neurobiological mechanisms u...
