This protocol forms the basis for a functional TCD experiment because almost all functional TCD experiments require placement of a fixation device to record a stable signal over an extended period of time. The main advantage of functional TCD is i

Functional transcranial Doppler ultrasound complements other functional imaging modalities, with its high temporal resolution measurement of stimulus-induced changes in cerebral blood flow within the basal cerebral arteries. This Methods paper gives step-by-step instructions for using functional transcranial Doppler ultrasound to perform a functional imaging experiment.
