Schizophrenia affects about 1% of the population. A hallmark of the disorder is increased dopamine D2 receptor sensitivity in the brain.

We assessed effects of nicotine on behavior and brain plasticity in an adolescent rodent model of schizophrenia with the goal of identifying targets for smoking cessation.

The Boys' Republic, Jonas Mueller
Electronic Theses and Dissertations
The young men in The Boys’ Republic live in a world that is continually falling apart. Their houses collapse into sinkholes, forest fires carve out chunks of their towns, plague spreads through their communes, the money runs out on the construction project where they work. This decay mirrors their own collapsing identities, as they are forced to question their mastery of nature, their nostalgia for their youth, their relationships with others, and the value of masculinity itself. Drawing on the work of writers like Dennis Cooper, Flannery O’Connor, and Benjamin Percy, The Boys’ Republic depicts men in the midst of …
