In daily life, action selection and decision-making are constantly biased by implicit value signals. When choosing a place for dinner on a Friday night, the estimated value of each restaurant will not only depend on a deliberate inspection of the menus but also on less conscious cues such as the atmosphere in the restaurant. Despite the crucial impact of implicit value cues on daily living choices, the exact contribution of the primary motor cortex to the encoding of this source of information remains obscure. In this talk, I will present the results of a recently published study (Derosiere et al., 2017, NeuroImage) in which we show that the human primary motor cortex is involved in the encoding of implicit value information during motor decisions. A thorough description of the dynamics of this encoding during reinforcement learning and decision-making will be provided.
