Asymmetrical modulations of decision and movement speeds during self-paced foraging reveal the dorsal striatum selective contribution to effort sensitivity

How quickly humans and other animals take decisions and move often covary with the utility of their goals, suggesting the existence of a shared mechanism controlling the speeds of action selection and execution. To test this hypothesis, we developed a self-paced foraging task in which rats run back-and-forth across a motorized treadmill to collect drops of water, and separately manipulated reward and effort. We used simple models to 1) quantify changes in running speed and in the pause between runs (run and inter-run durations) and 2) explore algorithmic and neural principles controlling these
