Two previous studies in which we recorded slow brain potential shifts over the scalp revealed performance-dependent effects that sustained one prominent model of timing mechanisms. These effects seemed to be derived from the supplementary motor area (SMA). Event-related functional magnetic resonance imagery (fMRI) was used to check this hypothesis. Brain activations were contrasted in Time production and (control) Force production tasks involving left-hand responding. These tasks, presented in… CONTINUE READING
