Dopamine release in human associative striatum during reversal learning

F. Grill, M. Guitart-masip, et al.

Simultaneous [11C]Raclopride PET-fMRI reveals dopamine release in associative striatum when reward contingencies flip, with peak receptor occupancy linked to reward prediction errors and sensitivity to mistakes, and overlapping fMRI signals for perseverance errors. This research was conducted by Filip Grill, Marc Guitart-Masip, Jarkko Johansson, Lars Stiernman, Jan Axelsson, Lars Nyberg, and Anna Rieckmann.
