“…Forty-eight colorful images each of high-calorie foods (e.g., hamburger, doughnuts, and fried chicken wings) and low-calorie foods (e.g., tomatoes, carrots) were used. All images were taken from a set previously used in our studies (Lyu and Jackson, 2016; Lyu et al, 2016, 2017), and edited to be homogeneous with respect to background color.…”

Previous research demonstrated the associations between cognitive biases toward food cues and binge eating (BE) behavior. To determine the characteristics of conflict monitoring to food cues in women who binge eat and non-eating disordered controls, a flanker task featured high-caloric food and low-caloric food images was used to examine conflict monitoring with measures of accuracy and reaction time. Women who binge eat displayed longer reaction times (RTs) to incongruent trials (i.e., flanked by pictures from the different category) than to congruent trials (i.e., flanked by pictures from the same category), while controls showed no such difference. This finding demonstrated women who binge eat displayed a general flanker effect toward food-related stimuli compared to controls. Faster reaction times in response to high-caloric food images disturbed by low-caloric food images predicted lower self-reported motor impulsiveness in the women who binge eat, but not in controls. These data suggest a relative conflict monitoring deficit in women with BE pathology.

“…One food-specific go/no-go adaptation was used to examine reaction times and task performance in women with and without binge eating and isolate food-specific inhibitory control deficits [113]. This task included images of both low and high-calorie foods and images of household items.…”

“…This task included images of both low and high-calorie foods and images of household items. Across six runs, the task examined go responses to high-calorie foods compared with no-go responses to household items, go responses to low-calorie foods compared with no-go responses to household items, go responses to household items compared with no-go responses to high-calorie foods, go responses to household items compared with no-go responses to low-calorie foods, go responses to high-calorie foods compared with no-go responses to low-calorie foods, and go responses to low-calorie foods compared with no-go responses to high-calorie foods [113]. Teslovich and colleagues [114] developed a similar go/no-go task that included control images of toys instead of household items and did not include the two runs that directly contrasted high-calorie go cues versus low-calorie no-go cues and vice-versa.…”

“…All food and non-food images used in the first study were matched on a variety of dimensions, including brightness, complexity, and color composition [113], but whether participants perceived the food and non-food images as equally pleasant or rewarding is unknown. In the second study, an independent sample rated all stimuli for valence and arousal to ensure food and non-food stimuli were matched on these parameters [114], but the images were not matched on visual characteristics like complexity and color.…”

Recurrent binge eating, or overeating accompanied by a sense of loss of control, is a major public health concern. Identifying similarities and differences among individuals with binge eating and those with other psychiatric symptoms and characterizing the deficits that uniquely predispose individuals to eating problems are essential to improving treatment. Research suggests that altered reward and control-related processes may contribute to dysregulated eating and other impulsive behaviors in binge-eating populations, but the best methods for reliably assessing the contributions of these processes to binge eating are unclear. In this review, we summarize standard neurocognitive and neuroimaging tasks that assess reward and control-related processes, describe adaptations of these tasks used to study eating and food-specific responsivity and deficits, and consider the advantages and limitations of these tasks. Future studies integrating both general and food-specific tasks with neuroimaging will improve understanding of the neurocognitive processes and neural circuits that contribute to binge eating and could inform novel interventions that more directly target or prevent this transdiagnostic behavior.

“…BED patients have displayed stronger inhibitory deficits on the Go/No-go task compared with obese individuals ( 4 , 9 ). On the other hand, in both BED ( 10 ) and obesity ( 11 ), a diminished ability to inhibit responses related to food on the Go/No-go task compared with lean controls has been evidenced. These data suggest that the poor decision-making and the uncontrolled impulse may be facilitated, having as a consequence overeating in both groups.…”

Longer Cortical Silent Period Length Is Associated to Binge Eating Disorder: An Exploratory Study

et al. 2020

Introduction: Although binge eating disorder (BED) is an eating disorder and obesity is a clinical disease, it is known that both conditions present overlapped symptoms related to, at least partially, the disruption of homeostatic and hedonistic eating behavior pathways. Therefore, the understanding of neural substrates, such as the motor cortex excitability assessed by transcranial magnetic stimulation (TMS), might provide new insights into the pathophysiology of BED and obesity. Objectives: (i) To compare, among BED, obesity, ex-obese, and HC (healthy control) subjects, the cortical excitability indexed by TMS measures, such as CSP (cortical silent period; primary outcome), SICI (intracortical inhibition), and ICF (intracortical facilitation; secondary outcome). (ii) To explore the relationship of the CSP, eating behavior (e.g., restraint, disinhibition, and hunger), depressive symptoms, and sleep quality among the four groups (BED, obesity, ex-obese, and HC). Methods: Fifty-nine women [BED ( n = 13), obese ( n = 20), ex-obese ( n = 12), and HC ( n = 14)] comprise the total sample for this study. Assessments: cortical excitability measures (CSP, SICI, and ICF), inhibition response task by the Go/No-go paradigm, and instruments to assess the eating psychopathology (Three-Factor Eating Questionnaire, Eating Disorder Examination Questionnaire, and Binge Eating Scale) were used. Results: A MANCOVA analysis revealed that the mean of CSP was longer in the BED group compared with other three groups: 24.10% longer than the obesity group, 25.98% longer than the HC group, and 25.41% longer than the ex-obese group. Pearson's correlations evidenced that CSP was positively associated with both eating concern and binge eating scores. Conclusion: The findings point out that BED patients present longer CSP, which might suggest an upregulation of intracortical inhibition. Additionally, CSP was positively correlated with Binge Eating Scale and eating concern scores. Further studies are needed.
