    Notes: Abstract Stimulation of muscarinic cholinergic receptors with the highly potent and selective receptor agonist oxotremorine produced hypothermia in rats. Alaproclate, a purported selective serotonergic reuptake inhibitor, potentiated this response. Destruction of central presynaptic serotonergic terminals with the potent cytotoxin p-chloroamphetamine (PCA) failed to attenuate the hypothermic response to oxotremorine in alaproclate-pretreated animals. These results could be taken to suggest that alaproclate may act, at least in part, via a non-serotonergic mechanism to potentiate the oxotremorine-induced hypothermic response.

    Enhancement of the memory of a previously learned aversive habit following pre-test administration of a variety of serotonergic antagonists in mice (1986)

    Notes: Abstract The present study examined the effects of pre-test administration of a number of serotonergic receptor antagonists on the retrieval of a previously learned aversive habit in the mouse. All of the receptor antagonists (pirenperone, ketanserin, mianserin, methysergide and metergoline) produced a dose-dependent increase in the latency to complete 5 s of drinking 48 h after training. This suppression of drinking could not be attributed to nonspecific effects of the drugs on behavior (e.g., illness, reduced thirst, or activity), as non-contingently trained mice failed to exhibit similar elevations in their test scores. These results are, therefore, further support for an important role for serotonin in the processes underlying learning and memory.

    MR/Har and MNRA/Har Maudsley rat strains: Differences in acoustic startle habituation (1988)
    Springer
    Behavior genetics 18 (1988), S. 663-669

    Notes: Abstract Female Maudsley Reactive (MR/Har) and Nonreactive (MNRA/Har) rats were tested for initial acoustic startle reactivity and within-session startle habituation. Subjects were exposed in each of five weekly sessions to 12 acoustic startle noise bursts at a 20-s interstimulus interval, a procedure in which genetically heterogeneous Sprague Dawley rats have been shown to exhibit robust within-session habituation. Although initial startle reactivity was comparable in the two strains, significant differences in withinssession habituation were observed. Specifically, MR/Har rats were observed to exhibit substantial within-session habituation to these acoustic stimuli, while rats of the MNRA/Har strain exhibited little, if any, habituation to these repeated acoustic stimuli. The basis for this dramatic difference in within-session startle habituation in these Maudsley rats is at present unexplained and under investigation.
