Interested in how we make preference-driven decisions, and how this is implemented in the brain?
We report that neural correlates of evidence accumulation (CPP, Mu/Beta) are also observed during value-based decisions.

Tracing the neural trajectories of evidence accumulation and motor preparation processes during voluntary decisions
Voluntary decisions have previously been described by where they arise in the brain and how actions corresponding to one's choice are prepared. However, the processes by which these internally guided ...

There's a movement in neuroscience suggesting we should be pursuing bigger bets with larger teams. I think there's a case for doing a bit of this, but I think it's a bad idea to prioritise it for two reasons, and a good case for saying we should be moving in the exact opposite direction. 🧠🧪
