Gambling Project 2014-2015

One of the main research focuses of EMMA (see other contents under the INTERESTS Section / Areas Covered) is the process of (impulsive) decision making and (pathological) gambling, as well as the role of forebrain neurocircuitry in this process. 

This project, sponsored and founded by the DPA - Italian Premier Ministry, is aimed to validate innovative animal models for pathological gambling and proneness to risky choices. The project is closed (started March 1, 2014 -- ended December 31, 2015).




- epigenetic markers for development of gambling proneness / aversion on brain and blood cells;
 October 2014 - The experiment investigated the development of gambling proneness vs. aversion in rats; after development of either, brain areas and plasma white cells (PBMCs) were screened, to measure changes in gene expression and accompanying, epigenetic changes in gene promoters. The goal is identifying a biomarker of gambling exposure and vulnerability

- DAT knockout rats as a model of impulsive and gambling traits, replicating our pioneer work

2015 - The experiment has been run by the student Stefano CINQUE (see students' page for update).
- Influence of a social partner on gambling traits (including bystanding vs. belief of theft);
 2015 - The experiment has been run by the student Gabriele ODDI in collaboration with Elsa ADDESSI. First paper published! There is another planned paper.
