We imaged motivational processes, implemented in a paradigm that varied the amount and reportability of monetary rewards for which subjects exerted physical effort. We show that, even when subjects cannot report how much money is at stake, they nevertheless deploy more force for higher amounts. Such a motivational effect is underpinned by engagement of a specific basal forebrain region. Our findings thus reveal this region as a key node in brain circuitry that enables expected rewards to energize behavior, without the need for the subjects`awareness. 10.1126/science.1140459 How the Brain Translates Money into Force: A Neuroimaging Study of Subliminal Motivation Mathias Pessiglione Liane Schmidt Bogdan Draganski Raffael Kalisch Hakwan Lau Ray Dolan Chris Frith doi:10.1126/science.1140459 Science, Vol. 316, No. 5826.
