1. INTRODUCTION

1.1. The mesolimbic dopamine (ML-DA) system

The ML-DA system (Fig.1) has received considerable attention due to its involvement in a range of psychological processes and neuropsychiatric diseases.

In fact, after the development of a DA theory of schizophrenia (Carlsson, 1974; 1978; Snyder, 1972; Meltzer & Stahl, 1976), additional ML-DA hypotheses have

been proposed to explain addiction (Wise & Bozarth, 1981; 1987; Koob, 1992), attention deficit hyperactivity disorder (ADHD) (Oades, 1987; Levy, 1991; Russel,

2000), depression (Willner, 1983a, 1983b, Dailly et al., 2004) as well as global behavioral activation (Gray, 1995) ranging from response persistence to behavioral

compulsions (Salamone & Correa, 2002; Everitt & Robbins, 2005)...
