Stretch-Evoked Motor Responses in the Brainstem are Modulated by Task Instructions

Rebecca C. Nikonowicz, Neha A. Reddy, Michelle C. Medina…·Fabrizio Sergi

The paper shows that task instructions modulate stretch-evoked motor responses in the human brainstem, as evidenced by changes in reticulospinal activation during fMRI.
