Reinforcement magnitude modulation of the rate-dependent effects of fluvoxamine is consistent with results in pigeons (Lamb and Ginsburg, 2008) and rats (Harper, 1999). In pigeons, rate-dependent effects of fluvoxamine diminished with increasing lengths of access to grain under a similar multiple fixed-interval schedule to the one used in this study (Lamb and Ginsburg, 2008). In rats, Harper (1999) reported that fluoxetine (which selectively inhibits serotonin reuptake like fluvoxamine) increased the response rate for the low-frequency reinforcement at a dose that had no effect on responding for the higher frequency reinforcement.
Sample text:```Quantitative geneticists have documented numerous cases of such interactions (Stuber et al. 1992; Ragot et al. 1995; Cockerham and Zeng 1996; Melchinger et al. 1998).```

Sample text:```Pre- and post-test1 both included measurements of the S-reflex, M-wave, and H-reflex, followed by an MVC. S-reflex testing was performed at 0 , as in the study by Avela et al. (1999).```

Sample text:```We used the stepwise multiple linear regression that accounts for repeated measurements in the same dog (4) first to test whether there was a difference among values for resistances and for elastances between control and emphysema at each mean Paw, considering the entire range of f and VT of forcing.```

Sample text:```Secondly, this effect was shown to be selectively due to CCK2 activation (Ladurelle et al. 1997) through mechanisms involving δ-opioid (Daugé et al. 1999) and D1-dopamine receptors (Ladurelle et al. 1993) that could be blocked by the selective antagonists naltrindole (a δ antagonist), and SCH23,390.```

Sample text:```The ¬¨¬µ-opioid receptor agonist morphine also induced inhibitory effects in both assays, in accordance with previous reports describing the opiate-mediated inhibition of the BSL evoked in mice by excitatory amino acids and neurokinins (Aanonsen et al. 1987; Takahasi et al. 1987; Wilcox 1988).```

Sample text:```The insertion of this time delay is critical because in previous work, it has been shown to allow the development of an inhibitory relationship between the outcome and the stimulus that follows; that is, it allows S1 to predict the absence of subsequent O1 delivery and S2 to predict the absence of subsequent O2 delivery; that is, stimuli trained in such manner exhibit properties (such as retardation) identical to those display by other conditioned inhibitors (Rescorla, 1969; Maier et al., 1976; Delamater et al., 2003).```

Sample text:```Indeed, strong correlations between inhibitions at different ISIs have been reported previously (Roshan et al. 2003) which would be consistent with this idea.```
