Objective: To compare the electrocortical processing of food pictures in participants with anorexia nervosa (n = 21), bulimia nervosa (n = 22), and healthy controls (HCs) (n = 32) by measuring the early posterior negativity, an event-related potential that reflects stimulus salience and selective attention. Methods: We exposed these three groups to a rapid stream of high- and low-calorie food pictures, as well as standard emotional and neutral pictures. Results: Event-related potentials in the…

Mood-induced changes in the cortical processing of food images in bulimia nervosa.
Neural processing of food and erotic cues in bulimia nervosa.
TLDR
The findings provide objective evidence that bulimia nervosa is characterized by dysregulated emotional processing that is not limited to food cues, and are discussed within a transdiagnostic perspective on food-related disorders.
Attention towards food: Conflicting mechanisms in anorexia nervosa
Motivational processing of food cues in anorexia nervosa: a pilot study
TLDR
Investigating the processing of food stimuli between patients diagnosed for anorexia nervosa (AN) and healthy controls by means of electroencephalography found food stimuli seem to be more motivationally relevant for AN patients than for healthy controls.
Enhanced Early Neuronal Processing of Food Pictures in Anorexia Nervosa: A Magnetoencephalography Study
TLDR
Analysis in source space and behavioral data suggested enhanced attention and cognitive control processes in response to food stimuli in AN, which may enable avoidance of salient food stimuli and maintenance of dietary restraint in AN.
Increased early motivational response to food in adolescent anorexia nervosa revealed by magnetoencephalography.
TLDR
MEG results speak against an overall reduced motivational response to food in anorexia nervosa, and relative increased early food processing in the visual cortex suggests greater motivated attention.
Eat your troubles away: Electrocortical and experiential correlates of food image processing are related to emotional eating style and emotional state
Altered Food-Cue Processing in Chronically Ill and Recovered Women with Anorexia Nervosa
TLDR
Despite weight recovery, neural processing of food cues is also altered in recovered AN patients, and evidence for increased TD control in AN and REC is found.
Event-Related Potentials During Recognition of Semantic and Pictorial Food Stimuli in Patients With Anorexia Nervosa and Healthy Controls With Varying Internal States of Hunger
TLDR
Evidence is provided for a midline parietal P3b amplitude reduction in patients with AN, which might point to reduced network activation in AN even during satiety.
Brain responses to body image stimuli but not food are altered in women with bulimia nervosa
TLDR
Exposure to food and body image stimuli increased self-reported levels of anxiety, but not craving, in women with BN, and this study suggests that womenwith BN differ from HCs in the way they process body image,but not in the how they process food stimuli.

Differential motivational responses to food and pleasurable cues in anorexia and bulimia nervosa: a startle reflex paradigm
TLDR
These preliminary results suggest that BN patients demonstrated an exaggerated appetitive response to food but not to standardized positive cues, whereas SEM in AN patients points to a generalized failure to activate the appetitive motivational system.
Cerebral processing of food-related stimuli: Effects of fasting and gender
Deprivation selectively modulates brain potentials to food pictures.
TLDR
Results show that the ERPs to food pictures in a hungry, rather than satiated, state were associated with enlarged positive potentials over posterior sensor sites in a time window of 170-310 ms poststimulus, which suggests the enhanced processing of food cues primarily in occipito-temporo-parietal regions.

Brain dynamics in spider-phobic individuals exposed to phobia-relevant and other emotional stimuli.
TLDR
A temporal unfolding in perceptual processing from unspecific vigilance (P1) to preferential responding (EPN and LPP) to phobia-relevant materials in the spider phobia group is demonstrated, which is related to emotional relevance of the stimulus cues rather than reflecting a fear-specific response.
Attentional bias in eating disorders
TLDR
B biases were found for negative eating and neutral weight pictures, and for positive eating pictures in women with eating disorders; these biases were greater than those found in anxious and normal controls.
Hunger selectively modulates corticolimbic activation to food stimuli in humans.
TLDR
The hypothesis that the amygdala and associated inferotemporal regions are involved in the integration of subjective interoceptive states with relevant sensory cues processed along the ventral visual stream is supported.
Stimulus novelty and emotion perception: the near absence of habituation in the visual cortex
TLDR
Findings suggest the near absence of habituation in differential emotion processing during perceptual processing after stimulus repetition in rapid serial visual presentation of pictures.
