TL;DR: This highly powered collaborative effort showed subtle patterns of age-related structural brain abnormalities in MDD, and substantial within-group variance and overlap between groups were observed.

Neuroimaging effects of prenatal alcohol exposure on the developing human brain: a magnetic resonance imaging review
Kirsten A. Donald,Emma Eastman,Fleur M. Howells,Colleen M. Adnams,Edward P. Riley,Roger P. Woods,Katherine L. Narr,Dan J. Stein +7 more
TL;DR: There is a critical gap in the literature of MRI studies in alcohol-exposed children under 5 years of age across all MRI modalities, and the dynamic nature of brain maturation and appreciation of the effects of alcohol exposure on the developing trajectory of the structural and functional network argue for the prioritisation of studies that include a longitudinal approach.
Journal ArticleDOI
The neurobiology of methamphetamine induced psychosis.
TL;DR: The effects of methamphetamine on dopaminergic pathways are reviewed, with focus on its ability to increase glutamate release in the cortex and it is proposed that cortical GABAergic interneurons are particularly vulnerable to glutamate overflow as a result of subcellular location of NMDA receptors on interneerons in the cerebral cortex.
