Disruptions in effort-based decision-making following acute optogenetic stimulation of ventral tegmental area dopamine cells

Benjamin R. Fry, Nathan Pence, Andrew McLocklin, Alexander W. Johnson

This study shows that acute optogenetic stimulation of VTA dopamine cells disrupts effort-based decision-making in mice, with effects persisting even after stimulation stops.
