Noradrenaline and dopamine: sharing the Workload

Stan B Floresco. Trends Neurosci. 2015 Aug.

Abstract

Varazzani and colleagues explored how noradrenergic and dopaminergic neural activity relates to cost/benefit decisions involving effort. They show these systems may play complementary roles in resolving these decisions; dopamine encodes cost-discounted values of rewards, whereas noradrenergic cells modify activity in relation to the amount of effort required to obtain them.
