Mice attempt to retrieve pellets
Inhibiting or exciting D1 or D2 neurons had different impacts on the mouse. The first clip shows a mouse with both D1 and D2 neurons working as normal successfully retrieving the reward. The second clip shows a mouse whose D1 neurons have been excited failing to retrieve the reward due to an initial error. The third clip shows a mouse whose D2 neurons have been excited failing to retrieve the reward due to a final error. The video clips were published in the research paper in Cell Reports.
