Differences between three rat strains in sensitivity to prepulse inhibition of an acoustic startle response: influence of apomorphine and phencyclidine pretreatment

In the present study we have examined the effect of varying three prepulse parameters (prepulse intensity, prepulse duration, prepulse-pulse interval) on the level of prepulse inhibition (PPI) in Lister hooded, Wistar and Sprague-Dawley rats. The results indicate that each strain showed subtle di…
