The trip of a lifetime: hallucinogen persisting perceptual disorder

Australasian Psychiatry February 1, 2018 Lauren Anderson, Hannah Lake, Mark Walterfang

We describe the resurgence of visual pseudo-hallucinations in...

Mindfulness and dynamic functional neural connectivity in children and adolescents.

Behavioural Brain Research January 15, 2018 Hilary A Marusak, Farrah Elrahal, Craig A Peters et al.

Interventions that promote mindfulness consistently show salutary effects on cognition and emotional wellbeing in adults, and more recently, in children and adolescents. However, we lack understanding of the neurobiological mechanisms underlying mindfulness in youth that should allow for more judicious application of these interventions in clinical and educational settings. Using multi-echo...
