Temporal Dynamics of Brain Activity Predicting Sense of Agency over Muscle Movements

JP Veillette, P Lopes, HC Nusbaum - Journal of Neuroscience, 2023 - Soc Neuroscience
Our muscles are the primary means through which we affect the external world, and the
sense of agency (SoA) over the action through those muscles is fundamental to our self …

Scale invariance in fNIRS as a measurement of cognitive load
