We found that decreasing [ ( 3 ) H ] - ( + ) - PHNO dose from 5 . 6nmol / kg ( our previous dose ) to 0 . 6nmol / kg caused a > 60 % increase in [ ( 3 ) H ] - ( + ) - PHNO binding to D3 receptors in cerebellar lobes 9 and 10 , indicating that our previous study was indeed conducted under non - tracer dose conditions .
 Chemical: [ ( 3 ) H ] - ( + ) - PHNO; Chemical: [ ( 3 ) H ] - ( + ) - PHNO
