(a) the volume flow rate in an artery supplying the brain is 3.4 x 10-6 m3/s. if the radius of the artery is 5.6 mm, determine the average blood speed.(b) find the average blood speed as a constriction in the artery if the constriction reduces the radius by a factor of 2. assume that the volume flow rate is the same as that in part (a).

a) speed = 3.45 × 10^-2 m/s

b) speed = 1.38 × 10^-1 m/s

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
