Assessing brain-wide outcomes of dopamine system activation in the living rodent brain
In a recent study, Haas, Bravo, and colleagues integrated optogenetic stimulation with simultaneous functional in vivo positron emission tomography (PET)/magnetic resonance imaging (MRI) measurements in rats. By activating the nigrostriatal pathway in the substantia nigra pars compacta (SNc), they observed concurrent metabolic and hemodynamic fluctuations associated with the dopaminergic pathway in living animals at the whole-brain level.
