Recent evidence shows that cannabis use can impair neurocognitive function among adolescent-onset cannabis users, with more persistent use associated with greater decline (e.g. Meier et al 2012 in PNAS). This project will use neuropsychological and Magnetic Resonance Imaging (MRI) techniques to examine cognitive and neurobiological function in a cohort of early onset cannabis users (regular cannabis use before fifteen years of age) relative to cannabis users that began regular use after eighteen years of the age, and a non-cannabis using control group.
Anxiety disorders are among the most prevalent of all psychiatric disorders. Difficulty concentrating is symptomatic of anxiety disorders because attention is often compromised by biases to negative information; a fundamental bias observed in anxiety disorders that contributes to symptomology. This proof-of-concept study aims to evaluate the feasibility of a real-time functional Magnetic Resonance Imaging neurofeedback […]
