WebD-waves are recorded from epidural or subdural electrodes placed by the surgeon after opening. The initial Direct (“D”) signal seen in cervical and upper thoracic regions corresponds to an initial propagating action potential within corticospinal tract axons. It is triggered in cortical motor neuron axons, probably at a subcortical level. how to search for multiple words using grep
