The acoustic startle response (ASR), prepulse inhibition (PPI) of the ASR and the effects of haloperidol on the ASR and PPI were examined in C57BL/6J (B6) and DBA/2 (D2) inbred mouse strains and their F1 and F2 progeny. The startle stimulus was a 60-ms, 110-dB, 10-kHz tone; the prepulse stimuli were 20-ms white noise bursts at 56, 68 and 80 dB against a(More)
A two-stage strategy was used to identify and confirm quantitative trait loci (QTLs) associated with the changes in locomotor activity induced by a 1.5 gm/kg ethanol challenge. For stage 1, putative QTLs were identified by analysis of the strain means for 25 strains of the BXD recombinant inbred (RI) series (males only). QTLs were identified on chromosomes(More)
The effect of ethanol on the number of Fos-like immunoreactive (Fos-li) neurons was previously studied in the C57BL/6J (B6) and DBA/2J (D2) inbred mouse strains (Hitzemann and Hitzemann, Alcohol. Clin. Exp. Res. 21:1497-1507, 1997). The data obtained suggested that the locomotor activation response to ethanol found in the D2 but not the B6 strain was(More)
Moderate doses of ethanol (1–2 g/kg) markedly increase locomotor activity in some inbred mouse strains, for example, the DBA/2J (D2), but have relatively little effect in other strains, for example, the C57BL/6J (B6). In the present study, we conducted a genome-wide search in a B6D2 F2 intercross (N = 925) for quantitative trait loci (QTLs) associated with(More)
