Adverse psychiatric symptoms caused by cannabis are a significant concern, and Δ9-tetrahydrocannabinol (THC) has been identified as a key contributor to these symptoms. THC binds to cannabinoid type 1 receptors (CB1Rs), which are abundant in the brain and associated with cognition. The prefrontal cortex (PFC) is crucial for cognitive functions. However, the functions of CB1Rs in the PFC in...
3,4-Methylenedioxymethamphetamine (MDMA) is known to induce dependence and psychosis in humans. Brain-derived neurotrophic factor (BDNF) is involved in the synaptic plasticity and neurotrophy in midbrain dopaminergic neurons. This study aimed to investigate the role of BDNF in MDMA-induced dependence and psychosis. A single dose of MDMA (10mg/kg) induced BDNF mRNA expression in the prefrontal...
