Twenty-three healthy adults participated in two sessions usingfunctional magnetic resonance imaging (fMRI), one after a normalnight's sleep and a second after a night of sleep deprivation. Inboth sessions, participants rated how much they wanted various fooditems shown to them while they were inside the scanner. "Our goal was to see if specific regions of the brainassociated with food processing were disrupted by sleepdeprivation," said lead author Stephanie Greer, a graduatestudent at the Sleep and Neuroimaging Laboratory at the Universityof California, Berkeley. Results show that sleep deprivation significantly impaired brainactivity in the frontal lobe, a region critical for controllingbehavior and making complex choices, such as the selection of foodto eat. The study suggests that sleep loss may prevent the higherbrain functions normally critical for making appropriate foodchoices, rather than necessarily changing activity in deeper brainstructures that react to basic desire. "We did not find significant differences following sleepdeprivation in brain areas traditionally associated with basicreward reactivity," Greer said. "Instead, it seems to beabout the regions higher up in the brain, specifically within thefrontal lobe, failing to integrate all the different signals thathelp us normally make wise choices about what we should eat." She added that this failure of the frontal lobe to optimally gatherthe information needed to decide on the right types of foods to eat-- such as how healthy relative to how tasty an item may be -- mayrepresent one brain mechanism explaining the link between sleeploss and obesity. "These results shed light on how the brain becomes impaired bysleep deprivation, leading to improper food choices," Greersaid.
