Description

The overall goal of this protocol is to study synaptic density in two psychiatric disorders (namely schizophrenia and other psychotic disorders, and cannabis use disorder) with this exciting new PET tracer. Secondary outcomes will include electroencephalography (EEG). A battery of EEG paradigms assessing sensory, perceptual, and cognitive functions will also be administered. The primary dependent measures will be traditional event related potentials (ERPs; e.g. latency and amplitude) as well as time X frequency analysis (inter-trial coherence and spectral power).
