Midbrain dopamine neurons encode internal effort signal

Show abstract
Midbrain dopamine neurons of the ventral tegmental area (VTA) play a central role in both positive and negative motivation. As motivation and effort are intrinsically connected, we asked how the VTA dopamine neurons may also process internally driven effort signal. We designed two novel jumping tasks, the reward- and escape-motivated jumps, and revealed that the VTA dopamine neurons exhibit an effort-correlated activation during both jumping behaviors.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
