After The above analysis shows that after recogniton the cerebral blood flow chart shows an increase in wave amplitude values, a decrease in peak angle, and an ' improvement in the echo wave. The arm blood flow chart shows a decrease in the wave amplitude value, an increase in the peak angle, and a decrease in the echo wave. This demonstrates an increased elasticity in the cerebral blood vessels after recognition, a decrease in impedence, and an increase in the pulse flow. -37- Approved For Release 2001/03/07 : CIA-RDP96-00792R000300330001-8
