Nitrous oxide (N2O) has recently emerged as a potential fast-acting antidepressant but the cerebral mechanisms involved in this effect remain speculative. We hypothesized that the antidepressant response to an Equimolar Mixture of Oxygen and Nitrous Oxide (EMONO) would be associated with changes in cerebral connectivity and brain tissue pulsations (BTP). Thirty participants (20 with a major...
We investigated several aspects of the dopaminergic and serotonergic functions throughout brain development in rats prenatally exposed to MDMA ("ecstasy"). Pregnant rats were treated with MDMA (10 mg/kg s.c.) or saline from the 13th to the 20th day of gestation and studies were conducted on the progeny from both groups: (i) quantification of whole brain contents of DA, 5-HT and metabolites from...
