TL;DR: System-level insights are provided into the weaker tract strength of frontostriatal circuits in male smokers and their potential roles as neuroimaging markers for abstinence-induced craving and risk of lapse.

TL;DR: The higher dynamic range of the lFCD hubs is consistent with their role in the complex orchestration of interacting brain networks, particularly in medial occipitoparietal regions.

TL;DR: The test-retest reproducibility in regional brain metabolic responses was measured, and although the global and regional metabolic values were significantly lower for the repeated evaluation, the response to lorazepam was highly reproducible.

TL;DR: This article focuses on advances in the development of the radiotracers involved in neurotransmission, amino acid transport, protein synthesis, and DNA synthesis and concludes with a summary of some of the scientific and infrastructure needs that would expedite the development and introduction of new radiot Racers into biomedical research and the practice of medicine.

TL;DR: Findings suggest that the contrasting effects of alcohol in basal ganglia versus the insula are involved in the perception of 'feeling drunk' and that its contrasting effects in cerebellum versus those in frontal and parietal cortices are involvement in its motor incoordinating effects.
