The metabolic requirement that necessary for the function of neurons is provided by increase of regional cerebral blood flow. The most frequently, visual stimulation is used for measurement of reactivity. In the present study, we assessed the change of blood flow velocities during simple and complex stimulation at posterior cerebral arteries coupling to neuronal activity at occipital cortex. The 12 healthy individual were included study. The blood flow velocity changes acquired by TCD to complex visual stimulations (44,8±13,3 cm/s) were significantly higher than those of simple visual stimulation (30,0±10,3 cm/s)(p<0,001). Transcranial Doppler Sonography is noninvasive and low-priced cerebral hemodynamic assessment method, and gives information about cerebral perfusion with recording blood flow velocities of cerebral arteries.
