Gender Differences in Food Choice: Effects of Superior Temporal Sulcus Stimulation
Frontiers in Human Neuroscience, 2017Co-Authors: Valerio Manippa, Laura N. Van Der Laan, Caterina Padulo, Alfredo BrancucciAbstract:The easy availability of food has caused a shift from eating for survival to hedonic eating. Women, compared to men, have shown to respond differently to food cues in the environment on a behavioral and a neural level, in particular to Energy rich (compared to Low Energy) Foods. It has been demonstrated that the right posterior superior temporal sulcus (STS) is the only region exhibiting greater activation for high versus Low calorie food choices. In order to test for a possible causal role of STS in food choice, we applied high frequency transcranial random noise stimulation (tRNS) on STS assuming a different response pattern between males and females. Our participants (18 females, 17 males) performed a forced choice task between food pairs matched for individual liking but differed in calorie, during the left STS, right STS stimulation and sham condition. Male participants showed a general preference for Low calorie Foods compared to females. In addition, we observed in males, but not in females, an increase of high calorie food choice during right STS tRNS compared to sham condition and left STS tRNS. Finally, we found an increase of missed choices during right STS stimulation compared to sham condition and left STS stimulation. In conclusion, thanks to tRNS evidence, we both confirm the involvement and suggest a causal role of right posterior STS in feeding behavior. Moreover, we suggest that gender differences exist in STS mechanisms underlying food choice.

Neural reactivity to visual food stimuli is reduced in some areas of the brain during evening hours compared to morning hours: an fMRI study in women
Brain Imaging and Behavior, 2016Co-Authors: Travis D. Masterson, C. Brock Kirwan, Lance E. Davidson, James D. LecheminantAbstract:The extent that neural responsiveness to visual food stimuli is influenced by time of day is not well examined. Using a crossover design, 15 healthy women were scanned using fMRI while presented with Low- and high-Energy pictures of food, once in the morning (6:30–8:30 am) and once in the evening (5:00–7:00 pm). Diets were identical on both days of the fMRI scans and were verified using weighed food records. Visual analog scales were used to record subjective perception of hunger and preoccupation with food prior to each fMRI scan. Six areas of the brain showed Lower activation in the evening to both high- and Low-Energy Foods, including structures in reward pathways ( P

Visual analog scales were used to record subjective perception of hunger and preoccupation with food prior to each fMRI scan. Six areas of the brain showed Lower activation in the evening to both high- and Low-Energy Foods, including structures in reward pathways (P < 0.05). Nine brain regions showed significantly higher activation for high-Energy Foods compared to Low-Energy Foods (P < 0.05). High-Energy food stimuli tended to produce greater fMRI responses than Low-Energy food stimuli in specific areas of the brain, regardless of time of day. However, evening scans showed a Lower response to both Low- and high-Energy food pictures in some areas of the brain. Subjectively, participants reported no difference in hunger by time of day (F = 1.84, P = 0.19), but reported they could eat more (F = 4.83, P = 0.04) and were more preoccupied with thoughts of food (F = 5.51, P = 0.03) in the evening compared to the morning. These data underscore the role that time of day may have on neural responses to food stimuli. These results may also have clinical implications for fMRI measurement in order to prevent a time of day bias.

Neural Reactivity to Visual Food Stimuli in the Morning and Evening: An fMRI Study in Women
2014Co-Authors: Travis D. MastersonAbstract:Neural Reactivity to Visual Food Stimuli in the Morning and Evening: an fMRI Study in Women Travis Masterson Department of Exercise Sciences, BYU Master of Science Background: Visual food stimuli have been shown to influence desire to eat and may influence overall Energy intake. The purpose of this study was to determine the influence, if any, that time of day has on the neural response to visual food stimuli, as measured by functional magnetic resonance imaging (fMRI). Methods: Using a crossover design, 15 healthy women were scanned using fMRI while presented with Lowand high-Energy pictures of food, once in the morning (6:30–8:30 am) and once in the evening (5:00–7:00 pm). Diets were identical on both days of the fMRI scans and were verified using weighed food records. Pictures used were based on the work of Sweet et al. (2012). Visual analog scales were used to record subjective perception of hunger and preoccupation with food prior to each fMRI scan. Results: Nine brain regions showed significantly higher activation for high Energy stimuli compared to Low Energy stimuli (p < 0.05). Six areas of the brain showed Lower activation in the evening to both high and Low Energy stimuli including parts of some reward pathways (p < 0.05). Subjectively, participants reported no difference in hunger by time of day (F(1, 14) = 1.84, p = 0.19), but felt they could eat more (F = 4.83, p = 0.04) and were more preoccupied with thoughts of food (F = 5.51, p = 0.03) in the evening compared to the morning. Conclusions: High Energy food stimuli tended to produce greater fMRI responses than Low Energy Foods in specific areas of the brain, regardless of time of day. However, evening scans showed a Lower response to both food categories in some areas of the brain compared to the morning. These data may have clinical implications for fMRI measurement and practical implications for sensitivity to food cues and eating behavior.

Women, compared to men, have shown to respond differently to food cues in the environment on a behavioral and a neural level, in particular to Energy rich (compared to Low Energy) Foods. It has been demonstrated that the right posterior superior temporal sulcus (STS) is the only region exhibiting greater activation for high vs. Low calorie food choices. In order to test for a possible causal role of STS in food choice, we applied high frequency transcranial random noise stimulation (tRNS) on STS assuming a different response pattern between males and females. Our participants (18 females, 17 males) performed a forced choice task between food pairs matched for individual liking but differed in calorie, during the left STS, right STS stimulation and sham condition. Male participants showed a general preference for Low calorie (LC) Foods compared to females. In addition, we observed in males, but not in females, an increase of high calorie (HC) food choice during right STS tRNS compared to sham condition and left STS tRNS. Finally, we found an increase of missed choices during right STS stimulation compared to sham condition and left STS stimulation. In conclusion, thanks to tRNS evidence, we both confirm the involvement and suggest a causal role of right posterior STS in feeding behavior. Moreover, we suggest that gender differences exist in STS mechanisms underlying food choice.

The influence of acute partial sleep deprivation on liking, choosing and consuming high- and Low-Energy Foods
Food Quality and Preference, 1Co-Authors: Jeroen S. Benjamins, Paul A.m. Smeets, Ignace T. C. Hooge, Christian Benedict, Laura N. Van Der LaanAbstract:Abstract A wealth of cross-sectional studies found a link between sleep deprivation and food-related outcomes like Energy intake and BMI. Recent experimental studies suggest that this link is causal. However, the mechanisms through which sleep deprivation influences intake remain unclear. Here, we tested two prevailing hypotheses: that sleep deprivation leads to 1) increased food reward sensitivity and 2) decreased food-related self-control. In a within-subject study (n = 60 normal-weight females), we compared outcome measures under normal sleep and partial sleep deprivation conditions. Our outcome measures were 1) proxies for food reward sensitivity – liking of high and Low Energy Foods, 2) binary food choices ranging in level of self-control conflict, and 3) intake of high and Low Energy Foods. Eye-movements during food choice were measured with an eye-tracker to gain insights in implicit food choice processes. Food reward sensitivity outcomes showed a Lower liking of Low Energy Foods after partial sleep deprivation. More high Energy Foods were chosen after partial sleep deprivation independent of the level of self-control conflict. Intake of high Energy Foods was higher in the partial sleep deprivation condition. Lastly, the number of gaze switches between high and Low Energy Foods, an implicit measure of conflict in choice, was Lower in the high-conflict trials after sleep deprivation than after a normal night sleep. To conclude, the increased intake of high Energy Foods after sleep deprivation may be driven by a decreased liking of Low Energy Foods, rather than an increased liking of high Energy Foods. Further, sleep deprivation may affect self-control conflict detection as indicated by a Lower number of gaze switches between food options.
