- Our work, out at Cell, shows that the brain’s dopamine signals teach each individual a unique learning trajectory. Collaborative experiment-theory effort, led by Sam Liebana in the lab. The first experiment my lab started just shy of 6y ago & v excited to see it out: www.cell.com/cell/fulltex...
- We show that in learning to make decisions from naïve to expert, i)Individuals form diverse yet systematic learning trajectories. ii)Dopamine in select striatal regions acts as a teaching signal shaping the trajectories. iii)A deep RL model with heterogenous teaching signals accounts for the data.
- Bonus points i) We made the (big) data and codes publicly available (follow the links in the paper). ii) The paper is open access, thanks to our funders. So enjoy reading it in the train, in a beer garden or while cooking :)
