Examination of a social-learning program implemented in a maximum-security state hospital setting.

The present study examines the extent to which clients with serious mental illnesses (SMI) enrolled in a social-learning program (SLP) within a maximum-security state hospital were able to achieve discharge to less restrictive settings without requiring a return to maximum security. Retrospective analyses were undertaken to examine several time periods of the SLP's operation within maximum security. From 1988 to 2019, 248 clients were discharged from the SLP.

The role of nucleus accumbens adenosine-opioid interaction in mediating palatable food intake.

Nucleus accumbens micro-opioid stimulation leads to robust increases in the intake of highly palatable foods, such as a high-fat diet. While interactions between opioids and certain striatal neurotransmitters underlying this phenomenon have been explored, many potential interactions have not. Striatal adenosine has been shown to have a significant influence on striatal neurotransmission and locomotor activity behavior, however the interaction between opioids and adenosine on feeding behaviors has received less attention.
