in addition , our model predicted a ratio of forward-to-reverse glucose flux across the blood-brain barrier ( bbr ) ( 1.37 plus or minus 0.23 sd ) , the brain-to-bloodglucose concentration ratio across the bbb ( 0.633 plus or minus 0.14 ) , the relative tissue free-glucose space ( 17 plus or minus 7 % ) , the brain free-glucose concentration ( 13.6plus or minus 8.5 mg/100 g of tissue ) , and the brain free-glucose turnover time ( 2.96 plus or minus 1.98 min ) .
