title: [The effect of visual deafferentation on changes in the cerebral blood flow during photic stimulation].
abstract: With the aid of transcranial dopplerography, linear velocity of the blood flow was recorded in major cerebral vessels in resting and in photostimulation in 18 healthy subjects and 7 patients with unilateral lesion of visual pathway and exclusion of one half of the field of vision. The photostimulation accelerated the blood flow in middle cerebral arteries by 4.3% and in posterior cerebral arteries by 26.3% in healthy subjects. No acceleration of the blood flow occurred in posterior cerebral artery on the side of unilateral lesion of visual pathways.
