Sexual satiety modifies methamphetamine-induced locomotor and rewarding effects and dopamine-related protein levels in the striatum of male rats. Psychopharmacology (Berl) 2023; 240:797-812. [PMID: 36745226 DOI: 10.1007/s00213-023-06322-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 01/18/2023] [Indexed: 02/07/2023]
Abstract
RATIONALE Drug and natural rewarding stimuli activate the mesolimbic dopaminergic system. Both methamphetamine (Meth) and copulation to satiety importantly increase dopamine (DA) release in the nucleus accumbens (NAc), but with differences in magnitude. This paper analyzes the interaction between Meth administration and the intense sexual activity associated with sexual satiety. OBJECTIVES To evaluate possible changes in Meth-induced behavioral effects and striatal DA-related protein expression due to sexual satiety. METHODS Meth-induced locomotor activity and conditioned place preference (CPP) were tested in sexually experienced male rats that copulated to satiety (S-S) or ejaculated once (1E) the day before or displayed no sexual activity (control group; C). DA receptors and DA transporter expression were determined by western blot in the striatum of animals of all sexual conditions treated with specific Meth doses. RESULTS Meth's locomotor and rewarding effects were exacerbated in S-S animals, while in 1E rats, only locomotor effects were enhanced. Sexual activity, by itself, modified DA-related protein expression in the NAc core and in the caudate-putamen (CPu), while Meth treatment alone changed their expression only in the NAc shell. Meth-induced changes in the NAc shell turned in the opposite direction when animals had sexual activity, and additional changes appeared in the NAc core and CPu of S-S rats. CONCLUSION Sexual satiety sensitizes rats to Meth's behavioral effects and the Meth-induced striatal DA-related protein adaptations are modified by sexual activity, evidencing cross-sensitization between both stimuli.

Abstract
The concept of “social homeostasis”, introduced by Matthews and Tye in 2019, has provided a framework with which to consider our changing individual needs for social interaction, and the neurobiology underlying this system. This model was conceived as including detector systems, a control center with a setpoint, and effectors which allow us to seek out or avoid additional social contact. In this article, we review and theorize about the many different factors that might contribute to the setpoint of a person or animal, including individual, social, cultural, and other environmental factors. We conclude with a consideration of the empirical challenges of this exciting new model.

Abstract
Adolescence is known for its high level of risk-taking, and neurobiological alterations during this period may predispose to psychoactive drug initiation and progression into more severe use patterns. Stress is a risk factor for drug consumption, and post-weaning social isolation increases drug self-administration in rodents. This review aimed to provide an overview of the effects of adolescent social isolation on cocaine, amphetamine and nicotine use-related behaviours, highlighting the specific period when animals were submitted to stress and these drugs. We wondered if there was a specific period during adolescence that isolation stress would increase drug use vulnerability. A total of 323 publications from the Scopus, Web of Science and PubMed (Medline) electronic databases were identified using the words "social isolation" and "adolescence" and "drug" or "cocaine" or "amphetamine" or "nicotine", resulting in 24 articles after analyses criteria following the PRISMA statement. The main points raised were social isolation during adolescence increased cocaine self-administration, amphetamine and nicotine locomotor activity. We did not observe a pattern of a specific moment during the adolescent period that could lead to an increased vulnerability to drug use. The precise conditions under which adolescent social stress alters drug use parameters are complex and likely depend on several factors.

Abstract
In animals, personality variations in response to stress and energy demands have been established. Cognitive processing of negative stimuli correlates with stress response patterns. Still, the relative contribution of cognitive appraisal or physiological demands to the behavioural output needs to be clarified. In this study we utilized reactive (high-responsive, HR) and proactive (low-responsive, LR) rainbow trout strains to investigate how contrasting reactions to hypoxia are related to individual variation in metabolism and/or cognition. The HR-LR strains did not differ in standard metabolic rate or hypoxia tolerance. HR trout displayed more pronounced avoidance to a signal cue after being conditioned with hypoxia, suggesting that they experienced this stimulus more aversive than LR trout. Together with differences in forebrain c-fos activation patterns in dorsomedial pallium, these results suggest cognitive differences between the strains. These results demonstrate that differences in personality/stress coping style can be related to contrasts in cognition, which are independent of metabolic differences.

Pildervasser JVN, Abrahao KP, Souza-Formigoni MLO. Distinct behavioral phenotypes in ethanol-induced place preference are associated with different extinction and reinstatement but not behavioral sensitization responses. Front Behav Neurosci 2014; 8:267.

Abstract
Conditioned place preference (CPP) is a model to study the role of drug conditioning properties. In outbred strains, individual variability may affect some behavioral measures. However, there are few studies focusing on understanding how different phenotypes of ethanol conditioned behavior may influence its extinction, reinstatement, and behavioral adaptation measures. We used male Swiss Webster mice to study different phenotypes related to ethanol conditioning strength, reinstatement and behavioral sensitization. Mice went through a CPP procedure with ethanol (2.2 g/kg, i.p.). After that, one group of mice was submitted to repeated extinction sessions, while another group remained in their home cages without any drug treatment. Mice went through environmental and ethanol priming (1.0 g/kg, i.p.) reinstatement tests. Ethanol priming test reinstated the conditioned behavior only in the animals kept in the home-cage during the abstinence period. Besides, the ethanol conditioned behavior strength was positively correlated with the time required to be extinguished. In the second set of experiments, some mice went through a CPP protocol followed by behavioral sensitization (five i.p. administrations of ethanol 2.2 g/kg or saline per week, for 3 weeks) and another group of mice went through sensitization followed by CPP. No positive correlation was observed between ethanol CPP strength and the intensity of behavioral sensitization. Considering that different phenotypes observed in CPP strength predicted the variability in other CPP measures, we developed a statistics-based method to classify mice according to CPP strength to be used in the evaluation of ethanol conditioning properties.

Abstract
RATIONALE Disruption of acquired drug-cue associations can effectively decrease relapse. The benefits of extinction training as opposed to abstinence have been reported. Timing of extinction trials is an important variable. Finding an effective extinction regimen can optimize addiction therapies. OBJECTIVE To determine the effects of different drug-free periods on cocaine-conditioned place preference (CPP) in rats that either did or did not receive non-reinforced exposure to drug-associated stimuli. MATERIALS AND METHODS Male adolescent rats were trained for cocaine-CPP (5, 10, or 15 mg/kg, i.p.) in a biased manner for 8 days and then tested following different intervals. RESULTS Rats treated with 15 mg/kg cocaine displayed high and equal CPP on the first test, performed 1, 4, 7, or 14 days following conditioning. Expression of CPP during the test performed 1 day after conditioning was equal in the groups conditioned with 5, 10, or 15 mg/kg cocaine. When the interval before the first test was extended to 14 days, the group treated with 5 mg/kg did not show CPP. Rats treated with the three doses and tested repeatedly at 1, 7, and 14 days did not display CPP on the third test. CPP after treatment with 10 or 15 mg/kg cocaine was already extinguished in the second test but only for an interval of 1-14 days. CONCLUSIONS Maintenance of CPP was evident at least 2 weeks after forced abstinence. Extinguished CPP can be obtained after a single extinction trial, performed close to original training and followed by prolonged abstinence. However, with low doses of cocaine, abstinence alone may be sufficient to disrupt drug-cue associations.

Abstract
The use of a virtual reality environment (VRE) enables behavioral scientists to create different spatial contexts in which human participants behave freely, while still confined to the laboratory. In this article, VRE was used to study conditioned place preference (CPP) and aversion (CPA). In Experiment 1, half of the participants were asked to visit a house for 2 min with consonant music and then they were asked to visit an alternate house with static noise for 2 min, whereas the remaining participants did the visits in reverse order. In Experiment 2, we used the same design as Experiment 1, except for replacing consonant music with dissonant music. After conditioning in both experiments, the participants were given a choice between spending time in the two houses. In Experiment 1, participants spent more time in the house associated with the consonant music, thus showing a CPP toward that house. In Experiment 2, participants spent less time in the house associated with the dissonant music, thus showing a CPA for that house. These results support VRE as a tool to extend research on CPP/CPA in humans.
