Abstract
There is now evidence from multiple Phase II clinical trials that psychedelic drugs can exert long-lasting anxiolytic, anti-depressant, and anti-drug abuse (nicotine and ethanol) effects in patients. Despite these benefits, the hallucinogenic actions of these drugs at the serotonin 2A receptor (5-HT2AR) limit their clinical use in diverse settings. Activation of the 5-HT2AR can stimulate both G protein and β-arrestin (βArr) -mediated signaling. Lisuride is a G protein biased agonist at the 5-HT2AR and, unlike the structurally-related lysergic acid diethylamide (LSD), the drug does not typically produce hallucinations in normal subjects at routine doses. Here, we examined behavioral responses to lisuride, in wild-type (WT), βArr1-knockout (KO), and βArr2-KO mice. In the open field, lisuride reduced locomotor and rearing activities, but produced a U-shaped function for stereotypies in both βArr lines of mice. Locomotion was decreased overall in βArr1-KOs and βArr2-KOs relative to wild-type controls. Incidences of head twitches and retrograde walking to lisuride were low in all genotypes. Grooming was decreased in βArr1 mice, but was increased then decreased in βArr2 animals with lisuride. Serotonin syndrome-associated responses were present at all lisuride doses in WTs, but they were reduced especially in βArr2-KO mice. Prepulse inhibition (PPI) was unaffected in βArr2 mice, whereas 0.5 mg/kg lisuride disrupted PPI in βArr1 animals. The 5-HT2AR antagonist MDL100907 failed to restore PPI in βArr1 mice, whereas the dopamine D2/D3 antagonist raclopride normalized PPI in WTs but not in βArr1-KOs. Clozapine, SCH23390, and GR127935 restored PPI in both βArr1 genotypes. Using vesicular monoamine transporter 2 mice, lisuride reduced immobility times in tail suspension and promoted a preference for sucrose that lasted up to 2 days. Together, it appears βArr1 and βArr2 play minor roles in lisuride's actions on many behaviors, while this drug exerts anti-depressant drug-like responses without hallucinogenic-like activities.

Abstract
MDMA or 'ecstasy' (3,4-methylenedioxymethamphetamine) is a commonly used psychoactive drug that has unusual and distinctive behavioral effects in both humans and animals. In rodents, MDMA administration produces a unique locomotor activity pattern, with high activity characterized by smooth locomotor paths and perseverative thigmotaxis. Although considerable evidence supports a major role for serotonin release in MDMA-induced locomotor activity, dopamine (DA) receptor antagonists have recently been shown to attenuate these effects. Here, we tested the hypothesis that DA D1, D2, and D3 receptors contribute to MDMA-induced alterations in locomotor activity and motor patterns. DA D1, D2, or D3 receptor knockout (KO) and wild-type (WT) mice received vehicle or (+/-)-MDMA and were tested for 60 min in the behavioral pattern monitor (BPM). D1 KO mice exhibited significant increases in MDMA-induced hyperactivity in the late testing phase as well as an overall increase in straight path movements. In contrast, D2 KO mice exhibited reductions in MDMA-induced hyperactivity in the late testing phase, and exhibited significantly less sensitivity to MDMA-induced perseverative thigmotaxis. At baseline, D2 KO mice also exhibited reduced activity and more circumscribed movements compared to WT mice. Female D3 KO mice showed a slight reduction in MDMA-induced hyperactivity. These results confirm differential modulatory roles for D1 and D2 and perhaps D3 receptors in MDMA-induced hyperactivity. More specifically, D1 receptor activation appears to modify the type of activity (linear vs circumscribed), whereas D2 receptor activation appears to contribute to the repetitive circling behavior produced by MDMA.

Abstract
Lesions were produced in the median and the dorsal raphe nuclei of the rat, and the effects of these injuries on various behaviors were studied. The median raphe lesions had facilitatory effects on the male rat sexual behavior, as evidenced by a decrease in the number of intromissions prior to ejaculation, as well as shortening of the ejaculation latency and the postejaculatory interval. No effects were seen on the masculine sexual behavior after lesions in the dorsal raphe nucleus. The median raphe lesions drastically increased the locomotory activity whereas the dorsal raphe lesions did not. Treatment with FG5893, a 5-HT1A agonist/5-HT2A receptor antagonist, increased the locomotor activity of the dorsal-raphe-lesioned rats but did not affect the median-raphe-lesioned animals. These results suggest that the dorsal and the median raphe nuclei play different roles in the neural regulation of the sexual behavior and locomotor activity of the male rat. The median raphe nucleus appears to exert a modulatory influence upon these behaviors, which probably is mediated by serotonergic neural pathways.

Abstract
The maintenance of intravenous (i.v.) cocaine self-administration appears to depend upon activation of dopamine terminals within mesocorticolimbic areas. Since the nonaddictive ergot derivative lisuride is a direct dopamine receptor agonist, the present study was designed to investigate whether administration of lisuride to rats trained to lever-press for IV self-administration of cocaine could affect the intake of cocaine. IP administration of several doses of lisuride reduced, in a dose-dependent manner, cocaine self-administration. In a control experiment, lisuride did not increase the psychomotor-activating properties of cocaine as measured by locomotor activity, suggesting that lisuride did not simply potentiate the activating effects of cocaine. The present results show that lisuride reduced IV cocaine self-administration in rats; the possibility of a new therapeutic approach to the treatment of cocaine abuse in humans using lisuride may therefore deserve clinical attention.

Abstract
The open-field test was used to study the involvement of dopaminergic and serotonergic mechanisms in the effects of 2-bromolisuride on locomotor activity in the rat. 2-Bromolisuride produced a dose-dependent inhibition of spontaneous locomotor activity. This is most likely due to an antagonistic action at postsynaptic dopamine receptors. Low doses of 2-bromolisuride potentiated apomorphine-induced hypermotility. This potentiating effect was not mediated by a blockade of presynaptic dopamine receptors, because it was not prevented by 6-OHDA lesion of the nucleus accumbens. The potentiating effect of 2-bromolisuride was completely blocked by the serotonin antagonists cyproheptadine and ritanserin. It is suggested that 2-bromolisuride possesses dopamine antagonistic and serotonin agonistic properties.

Abstract
The effect of lisuride (0.1 and 0.2 mg/kg IP) on the sexual behavior was studied in the adult, ovariectomized and chronically estradiol-primed female rats. The behavioral tests were done under dyadic interaction with males 60 min before and 30, 120 and 360 min after lisuride or saline injection. Lisuride induced a prompt, short-termed and dose-dependent loss of the precopulatory patterns (darting, hopping, presenting posture) while the effect on the copulatory (lordosis) behavior was weaker. A partial restoration of the precopulatory behavior was observed in the 120th min, the full restoration of the original precopulatory states was found in the 360th min. The inhibitory effect of lisuride on feminine sexual behavior is in contrast with its facilitatory effect on masculine sexual behavior in rats. The results suggest that the serotonergic system participates in the mediation of both copulatory (receptive) behavior and precopulatory (proceptive) behavioral patterns.

Abstract
B-HT920 is known to be a selective alpha 2-adrenoceptor agonist, and has been used in a study on morphine-withdrawal in rats. In accordance with other alpha 2-agonists B-HT920 was found to potentiate "jumping" and to reduce "body shakes." However, B-HT920 did not suppress body weight loss. Furthermore, it induced strong salivation and prevented ptosis (described for the alpha 1-adrenergic agonist ST-587). Rearing and locomotor activity appeared to be enhanced, an effect shared by dopamine-agonist lisurid. The effects of B-HT920 have been specified using the alpha-adrenergic antagonists yohimbine and prazosin and the dopamine antagonist haloperidol. Yohimbine could not antagonize any of the actions of B-HT920. However the increase in rearing and locomotion was blocked by haloperidol. The induction of salivation was prevented by prazosin. Pretreatment with prazosin showed a decrease in the loss of body weight caused by B-HT920, while pretreatment with yohimbine showed that B-HT920 induced an increased loss in body weight. These data suggest that B-HT920 under certain conditions exerts dopamine-agonistic actions in stimulating locomotor activity and alpha 1-adrenergic actions in inducing salivation and enhanced loss of body weight.
