“…A recent study using EEG showed that overweight and obese women, compared to healthy weight women, showed greater right parietal ERP P200 amplitude (early attentional processes) and shorter right parietal ERP P300 (enhanced maintenance of attentional processes; Hume, Howells, Rauch, Kroff, & Lambert, 2015). Imaging research, using fMRI, suggests that obese individuals, compared to lean individuals, show increased responsiveness in the gustatory (insula, frontal operculum), reward valuation regions (amgydala, ventralmedial prefrontal cortex, striatum) and cognitive control regions (orbitofrontal cortex) in response to images of palatable food (Bruce et al, 2010; Martin et al, 2010; Nummenmaa et al, 2012; Rothemund et al, 2007; Stice, Yokum, Blum, & Bohon, 2010; Stoeckel et al, 2009), cues that predict delivery of food (Stice, Spoor, Bohon, Veldhuizen, & Small, 2008), and to palatable food receipt (Boutelle et al, 2014; Ng, Stice, Yokum, & Bohon, 2011; Stice, Spoor, Bohon, Veldhuizen, et al, 2008).…”

Childhood obesity is associated with medical and psychological comorbidities, and interventions targeting overeating could be pragmatic and have a significant impact on weight. Calorically dense foods are easily available, variable, and tasty which allows for effective opportunities to learn to associate behaviors and cues in the environment with food through fundamental conditioning processes, resulting in measurable psychological and physiological food cue reactivity in vulnerable children. Basic research suggests that initial learning is difficult to erase, and that it is vulnerable to a number of phenomena that will allow the original learning to re-emerge after it is suppressed or replaced. These processes may help explain why it may be difficult to change food cue reactivity and overeating over the long term. Extinction theory may be used to develop effective cue-exposure treatments to decrease food cue reactivity through inhibitory learning, although these processes are complex and require an integral understanding of the theory and individual differences. Additionally, learning theory can be used to develop other interventions that may prove to be useful. Through an integration of learning theory, basic and translational research, it may be possible to develop interventions that can decrease the urges to overeat, and improve the weight status of children.

“…In an analysis of particular EEG correlates of dysfunctional eating behaviour, Tammela et al () found EEG beta activity to be associated with disinhibition in female binge eaters. Similarly, Hume, Howells, Rauch, Kroff, and Lambert () showed excess EEG beta activity after food cue exposure in overweight women. Thus, states of tense arousal marked by elevated EEG beta activity may contribute to binge eating behaviours.…”

Neurofeedback Against Binge Eating: A Randomized Controlled Trial in a Female Subclinical Threshold Sample

Brain-directed treatment techniques, such as neurofeedback, have recently been proposed as adjuncts in the treatment of eating disorders to improve therapeutic outcomes. In line with this recommendation, a cue exposure EEG-neurofeedback protocol was developed. The present study aimed at the evaluation of the specific efficacy of neurofeedback to reduce subjective binge eating in a female subthreshold sample. A total of 75 subjects were randomized to EEG-neurofeedback, mental imagery with a comparable treatment set-up or a waitlist group. At post-treatment, only EEG-neurofeedback led to a reduced frequency of binge eating (p = .015, g = 0.65). The effects remained stable to a 3-month follow-up. EEG-neurofeedback further showed particular beneficial effects on perceived stress and dietary self-efficacy. Differences in outcomes did not arise from divergent treatment expectations. Because EEG-neurofeedback showed a specific efficacy, it may be a promising brain-directed approach that should be tested as a treatment adjunct in clinical groups with binge eating.
