Newest firstIntroduction Cannabinoid receptor type 1 (CB1) is extensively distributed across brain regions that are crucial for emotional processing, social cognition, and anxiety, including the prefrontal cortex, amygdala, and hippocampus. Dysregulation of CB1 receptors (CB1Rs) has been associated with several disorders characterized by impaired empathy, social behavior, and anxiety. Accordingly, this study investigates the…
Open article record in new tab ↗Growing evidence indicates that adolescent substance abuse is now an alarming concern that imposes a considerable socio-economic burden on societies. On the other hand, numerous studies have shown that due to specific neurophysiological features, the brain is more vulnerable to the adverse effects of psychoactive drugs at an early age. Unfortunately, these negative effects are not limited to the period of drug use…
Open article record in new tab ↗Introduction Transcranial direct current stimulation (tDCS) has been studied as an adjunctive treatment option for substance use disorders (SUDs). Alterations in brain structure following SUD may change tDCS-induced electric field (EF) and subsequent responses; however, group-level differences between healthy controls (HC) and participants with SUDs in terms of EF and its association with cortical architecture hav…
Open article record in new tab ↗Introduction Several neuropsychiatric disorders, such as addiction, have indicated variations in the levels of neurotrophic factors. As an extremely addictive stimulant, methamphetamine (METH) is associated with rising levels of abuse worldwide. We have recently demonstrated that repeated intracerebroventricular (ICV) of cannabidiol (CBD), the most important non-psychotomimetic compound, can lead to diminished imp…
Introduction Prenatal exposure to Marijuana (MJN) has been associated with various brain deficits. The main activity in marijuana, Δ9-Tetrahydrocannabinol (THC), crosses the placenta and affects fetal brain development. Despite this, marijuana remains a commonly abused substance among pregnant women. The current study examined the histological and biochemical changes in the Superior Colliculus (SC) and Lateral Gen…
Open article record in new tab ↗Introduction For centuries, cannabinoids are known to be effective in pain relief. Itch is an unpleasant sensation that provokes a desire to scratch. Since itch and pain are two sensations sharing a lot in common, we aimed to investigate whether the cannabinoid agonist WIN 55,212-2 reduces serotonin-induced scratching behavior and also observe whether modulation of Nitric Oxide (NO) production mediates the antipru…
Open article record in new tab ↗Introduction Previous studies have shown that the cannabinoid system is involved in anxiety. In addition, transient receptor potential vanilloid type-1 (TRPV1) channels are new targets for the development of anxiolytics. The present study investigated the possible interaction between the cannabinoid and vanilloid systems on anxiety-like behavior in rats. Methods Four different groups of male Wistar rats received i…
Open article record in new tab ↗Introduction This study investigates the effects of cannabinoid agonist WIN55-212-2 on acquisition and consolidation phases of the fear memory extinction and also on anxiety and motor activity. Methods In this study, we used SPS & S model to induce post-traumatic stress disorder. One week after SPS, to establish a conditioned fear memory, rats received an electric foot shock within shock chamber. After 24 h, for e…
Open article record in new tab ↗Introduction Anxiety is among the most common and treatable mental disorders. Adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. The elevated plus-maze (EPM) has broadly been used to investigate anxiolytic and anxiogenic compounds. The present study investigated the effects of intraperitoneal (IP) injection of cannabinoid CB1 receptor antagonist (AM251) in the presence of alp…
