From molecules… to behavior

2013_06_06_souriscity_0026rDopamine (DA) projections from the midbrain (including ventral tegmental area and substantia nigra) to striatum and frontal cortex play a major role in behavioral actions controlled by reward and in the formation of habits. The dopaminergic system is also involved in drug addiction. Using a combination of behavioral analysis, in vivo and in vitro electrophysiological recordings, genetic tools and optogenetics, we analyze the modifications of DA network dynamics in the different steps leading to nicotine addiction, including genetic and environmental factors, and the consequences of these modifications on decision making.
