This study employed a passive avoidance task to examine the impact of acute mild stress and equivalent doses of exogenous corticosterone on fear memory retrieval and extinction in male mice. Subsequently, we investigated the potential therapeutic effects of Ginkgo biloba extract, EGb 761, on memory impairments induced by stress and corticosterone. Corticosterone was administered systemically 30 min before memory reactivation to model glucocorticoid activity during retrieval. Mild acute stress, like the stress levels typically experienced before an exam, was induced through 20-min restraint immediately before reactivation in separate groups. EGb 761 was injected 30 min before corticosterone or stress exposure. Results demonstrated that both corticosterone and acute stress impaired context-specific fear memory retrieval and enhanced subsequent extinction. Pretreatment with EGb 761 inhibited these impairing effects of acute stress and corticosterone on avoidance memory retrieval and extinction. Our findings suggest that the glucocorticoid system and acute stress markedly influence avoidance memory retrieval and extinction. Ginkgo biloba may possess therapeutic and memory-enhancing effects, particularly in stressful situations.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":"97-106"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142667228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Access to a wheel for voluntary running abolished this effect in male rats, suggesting an attenuating effect of physical exercise on the negative affect induced by reward downshift and its consequences on drug intake. The present study analyzed this effect in female rats. Sixty-four food-deprived female Wistar rats received 32% sucrose [4% (Experiment 1) or 2% (Experiment 2) in controls] during 10, 5-min preshift sessions followed by 4% (Experiment 1) or 2% (Experiment 2) sucrose during 5 postshift sessions. Immediately after each consummatory session, animals were exposed to a 2-h, two-bottle preference test involving 32% alcohol vs. water. Half of the animals also had access to a running wheel during the preference test. The results showed (a) lower sucrose consumption in the downshifted groups (32-4% and 32-2%) compared to the unshifted controls (4-4% and 2-2%, respectively); (b) higher alcohol preference in downshifted groups without access to a wheel compared with downshifted groups with access to the wheel (Experiments 1 and 2); and (c) increased alcohol intake (g/kg) after experiencing reward downshift in animals without access to the wheel (Experiment 1). Voluntary wheel running thus reduced alcohol intake in female rats experiencing reward downshift. These findings are comparable to previous results reported in male rats and support the usefulness of physical exercise to prevent alcohol self-medication induced by frustrative nonreward.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":"144-155"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142725334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal dose of hesperidin (10 mg/kg) for the antidepressant potential was determined after 7 consecutive days of treatments, demonstrating decreased latency to eat and increased food consumption in novelty suppressed feeding, and decreased immobility time in tail suspension test (TST). Moreover, the optimal dose also reversed the depressive phenotypes of Institute of Cancer Research mice exposed to chronic unpredictable mild stress (CUMS), including reduced immobility time in the TST and increased sucrose preference in the sucrose preference test. In addition, hesperidin increased the expression of AMPA receptor protein (Glur1) and synaptic proteins (BDNF, PSD95, synapsin1) in the hippocampus of CUMS-exposed mice. Furthermore, inhibition of AMPA receptor activity by NBQX blocked the effect of hesperidin in reversing the depressive phenotypes, upregulated the expression of synaptic proteins (BDNF, PSD95, synapsin1) and cFOS-positive cells in the hippocampus, and increased the number of Ki67-positive cells in the dentate gyrus of the hippocampus of CUMS-exposed mice.

In adult male mice, both monlunabant and rimonabant reduced appetite and antagonized CB 1 agonist-induced hypothermia. Monlunabant was consistently less potent than rimonabant in both appetite suppression and blocking hypothermia. The cannabinoid agonist HU-210 produced profound hypothermia, which was significantly attenuated by 10 mg/kg of either drug and by 3 mg/kg of rimonabant. Similarly, both drugs reduced appetite in food-deprived mice with limited access to preferred food at the same doses that were effective in the hypothermia assay. Lower doses of monlunabant, which likely saturated peripheral receptors, had no effect on appetite. These findings suggest that monlunabant suppresses appetite mainly through antagonism of central CB 1 receptors. Consequently, monlunabant and other second-generation CB 1 antagonists being developed for obesity may carry a similar risk of adverse psychiatric effects, as previously observed with rimonabant.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":"156-160"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of our study was to profile behavioral performance upon oral administration of methylphenidate (2.5 mg/kg) and modafinil (64 mg/kg) - two popular cognitive enhancers - and upon their discontinuation. We modeled cognitively demanding challenges in neurotypical individuals using a behavioral task where Wistar - Lewis rats had to withhold responses for a specified time to obtain food rewards. This task allowed us to extract several measures of behavioral performance associated with clinically meaningful indices, such as compulsive-like responding, incapacity to wait (impulsivity), time estimation (precision and accuracy), and attentional lapses. Our study design involved examining these behavioral indices in subjects administered either methylphenidate, modafinil, or vehicle. We found that subjects administered modafinil obtained fewer rewards and were less efficient in reward pursuing than the vehicle group; this result was likely due to a drug-induced inability to wait. Upon modafinil discontinuation, subjects earned more rewards but did not entirely catch up with the vehicle group. As for methylphenidate, neither favorable nor unfavorable effects were found in our main analyses. However, an exploratory analysis of changes in behavioral performance within sessions suggested that methylphenidate fostered favorable, yet short-lived, effects. We discuss our results in terms of the risks and cost-benefits of doses above or below the effective dose of cognitive enhancement drugs.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":"76-96"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143063388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leptin, an adiposity hormone known for its role in energy homeostasis, has been shown to improve insulin sensitivity and regulate blood glucose levels in diabetic populations. Beyond its metabolic effects, leptin also has the potential to mitigate psychiatric complications such as depression and anxiety. Notably, leptin receptors are predominantly expressed on dopamine (DA) neurons in the brain, hinting that leptin may orchestrate DA activity by serving as its endogenous modulator. This review examines the role of leptin as a potential common link between type-2 diabetes and mood disorders, particularly through its effects on DA function. This article proposes defective leptin signaling as a vital mechanism contributing to psychiatric complications and compromised DA functions in type-2 diabetes, highlighting leptin as a promising therapeutic target for addressing metabolic and psychiatric comorbidities.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143623293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guanfacine, a selective alpha-2A adrenergic receptor agonist, has been used to treat stress-related disorders characterised by impaired prefrontal cortex function. By acting on both presynaptic inhibitory autoreceptors and postsynaptic heteroreceptors, guanfacine attenuates stress reactivity and enhances cognition. However, its effectiveness in treating trauma-related anxiety and risk-taking behaviour remains unclear. Leveraging the advantages of zebrafish (Danio rerio ) as a sensitive and efficient preclinical model which is ideal for stress research, we explored the impact of traumatic stress exposure combined with varying concentrations of guanfacine in adult zebrafish. Zebrafish were evaluated for trauma-related anxiety using both the novel tank test (NTT) and a novel version of the open-field test (nOFT), the latter which was also used to investigate risk-taking behaviour. We found that (1) traumatic stress exposure led to heightened risk-taking behaviour in the nOFT, and (2) low-to-moderate concentrations of guanfacine (3-20 µg/L) attenuated anxiety-like, but not risk-taking behaviour, with the highest concentration (40 µg/L), showing no effect. These results highlight the complex role of NA in modulating dysregulated behaviours during traumatic events and indicate the potential of guanfacine for improving trauma-related anxiety and risk-taking behaviour.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":"47-59"},"PeriodicalIF":1.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
