Bilateral transcranial Doppler ultrasound measures of blood flow velocities in the middle cerebral artery of college students were taken during three 90‐second memory tasks: generating and maintaining images, remembering letters, and answering general knowledge questions. Blood flow velocities in the middle cerebral artery during each task increased significantly over their respective 30‐second baseline period. Differences in blood flow velocities due to the kind of memory task, the middle cerebral artery sampled (right or left), or subject gender were not significant.
