Projects

PsiConnect Study

• Status: Complete, with multiple outputs under review.
• Scientific Lead on Australia’s first psychedelic imaging trial, investigating interactions between psilocybin, brain connectivity, context and behaviour in healthy adults.
• World’s largest fMRI dataset collected under psychedelics to date by sample size (N = 65).
• Extensive baseline imaging and imaging under the effects of 19 mg psilocybin using both MRI and EEG, with before and longitudinal after behavioural measures.
• Large supportive interdisciplinary team including Leonardo Novelli, Moein Khajehnejad, and Adeel Razi.
• This research reveals a subject-level signature of the transformative psychedelic state and advanced how we understand context-dependent reorganisation of brain networks during the psychedelic state.

Keio University Psilocybin Trial

Lead investigators: Professor Hiroyuki Uchida and Keisuke Kusudo

• Japan’s first serotonergic psychedelic clinical trial, evaluating safety and efficacy of psilocybin in treatment-resistant depression, with low (10 mg) and high (25 mg) doses across multiple sessions.
