文摘

A device to measure reward value of liquids in humans was validated. Time spent sipping was longer after 21-h than 1-h of food deprivation. Time spent sipping, and pressure exerted, were higher for sweet than non-sweet drinks. Sweet-non-sweet differences in pressure exerted, and in “wanting”, were correlated. Sleep-restricted subjects worked less for sweet reward, despite increased desire.
