The paper identifies synthetic plastics in human brain microvascular deposits using fluorescence and chemical analysis, suggesting potential links to microvascular pathology.

This study shows that CRF1 antagonist R121919 and naltrexone restore prefrontal cortex functional connectivity during alcohol withdrawal through distinct mechanisms involving modularity and connectivity changes.

The paper investigates how cholinergic systems contribute to changes in brain functional connectivity during nicotine withdrawal in male mice, identifying two distinct long-range cholinergic networks and associated genes.

The paper uses single-cell whole-brain imaging to analyze how psychostimulant withdrawal alters brain functional architecture, finding reduced modularity as a common feature across drugs.

The paper validates the three-stage theory of addiction using single-cell whole-brain imaging in a mouse model, showing abstinence reduces brain modularity and clusters regions corresponding to each stage.
