Experiencing Effects of Cocaine and Speed with Self-Regulation Therapy.
2015
AbstractThis study demonstrates the efficacy of Self-Regulation Therapy (SRT) to induce effects of cocaine and speed in a single session. SRT is a suggestion procedure of sensorial recall exercises (salivation, feeling of weight, tension, etc.) that increases the capacity to reproduce all sensation types and those that drugs produce. The Self-Regulation Scale (SRS) measures this capacity. Four groups participated, formed according to drug use: Group 1 (uses no illegal drugs); Group 2 (experimentally uses cannabis only); Group 3 (moderate drug users); Group 4 (regular drug users, especially stimulants). All four groups participated in an SRT session to induce relaxation. No differences in th…
Serotonin, the Prefrontal Cortex, and the Antidepressant-Like Effect of Cannabinoids
2007
Preclinical and clinical studies show that cannabis modulates mood and possesses antidepressant-like properties, mediated by the agonistic activity of cannabinoids on central CB1 receptors (CB1Rs). The action of CB1R agonists on the serotonin (5-HT) system, the major transmitter system involved in mood control and implicated in the mechanism of action of antidepressants, remains however poorly understood. In this study, we demonstrated that, at low doses, the CB1R agonist WIN55,212-2 [R(+)-[2,3-dihydro-5-methyl-3-[(morpholinyl)]pyrrolo[1,2,3-de]-1,4-benzoxazinyl]-(1-naphthalenyl) methanone mesylate] exerts potent antidepressant-like properties in the rat forced-swim test (FST). This effect …
Lack of effects of anabolic-androgenic steroids on locomotor activity in intact male mice.
1999
Anabolic-androgenic steroid abusers have reported hyperactivity euphoria, and decreased fatigue, among other behavioral effects. It has been suggested that the effects of these substances on the central nervous system are similar to those of psychostimulants; however, the influence of steroids on general locomotor activity in laboratory animals is not well understood, especially how noncastrated male rodents are affected. In this study, spontaneous locomotor activity displayed by gonadally intact male mice submitted to several experimental conditions was analyzed. Different housing conditions (individual or cohabiting with a female), diverse steroids (testosterone propionate, nandrolone de…
Exercise-induced euphoria and anxiolysis do not depend on endogenous opioids in humans
2021
Abstract A runner's high describes a sense of well-being during endurance exercise characterized by euphoria and anxiolysis. It has been a widespread belief that the release of endogenous opioids, such as endorphins, underlie a runner's high. However, exercise leads to the release of two classes of rewarding molecules, endocannabinoids (eCBs) and opioids. In mice, we have shown that core features of a runner's high depend on cannabinoid receptors but not opioid receptors. In the present study, we aimed to corroborate in humans that endorphins do not play a significant role in the underlying mechanism of a runner's high. Thus, we investigated whether the development of two core features of a…
