Abstract:
Objective To determine the effect of thinking on intracranial blood flow velocities.Methods Transcranial Doppler(TCD)was used to measure the blood flow velocities of the cerebral arteries,when 10 normal persons were at rest and during thinking.Results The mean flow velocities(MFVs)of the cerebral arteries during thinking were significantly higher than those at rest,especially in the MCA and ACA.The MFVs were raised from between 10.3% to 14.3%.Conclusions Thinking can increase the blood flow velocities of cerebral arteries significantly.
