Decoupling motor plans from perceptual decisions to investigate whether and when decisions are embodied.

Decision making is a crucial part of our life: we sense information from the environment and perform our motor response. However, "whether" and "when" decisions are embodied still needs to be fully elucidated. Neuroimaging data obtained by the disentanglement of perceptual decision from motor preparation revealed an increase in connectivity between inferior frontal cortex and sensory regions, a...

Decoupling speed and accuracy in an urgent decision-making task reveals multiple contributions to their trade-off

A key goal in the study of decision making is determining how neural networks involved in perception and motor planning interact to generate a given choice, but this is complicated due to the internal trade-off between speed and accuracy, which confounds their individual contributions. Urgent decisions, however, are special: they may range between random and fully informed, depending on the amo...

Buildup of Choice-Predictive Activity in Human Motor Cortex during Perceptual Decision Making

Simple perceptual decisions are ideally suited for studying the sensorimotor transformations underlying flexible behavior. During perceptual detection, a noisy sensory signal is converted into a behavioral report of the presence or absence of a perceptual experience. Here, we used magnetoencephalography (MEG) to link the dynamics of neural population activity in human motor cortex to perceptual...
