IntroductionDespite the well-established evidence supporting the restorative potential of nature exposure, the neurophysiological underpinnings of the restorative cognitive/emotional effect of nature are not yet fully understood. The main purpose of the current study was to investigate the association between exposure to nature and electroencephalography (EEG) functional connectivity in the distress network.MethodsFifty-three individuals (11 men and 42 women; mean age 21.38 ± 1.54 years) were randomly assigned to two groups: (i) a green group and (ii) a gray group. A slideshow consisting of images depicting natural and urban scenarios were, respectively, presented to the green and the gray group. Before and after the slideshow, 5 min resting state (RS) EEG recordings were performed. The exact low-resolution electromagnetic tomography (eLORETA) software was used to execute all EEG analyses.ResultsCompared to the gray group, the green group showed a significant increase in positive emotions (F1; 50 = 9.50 p = 0.003) and in the subjective experience of being full of energy and alive (F1; 50 = 4.72 p = 0.035). Furthermore, as compared to urban pictures, the exposure to natural images was associated with a decrease of delta functional connectivity in the distress network, specifically between the left insula and left subgenual anterior cingulate cortex (T = −3.70, p = 0.023).DiscussionOur results would seem to be in accordance with previous neurophysiological studies suggesting that experiencing natural environments is associated with brain functional dynamics linked to emotional restorative processes.

Purpose Studies have shown significant associations of dissociative symptoms with both eating and addictive disorders; however, the different forms of dissociation have been relatively understudied in relation to food addiction (FA). The main aim of this study was to investigate the association of certain forms of dissociative experiences (i.e., absorption, detachment and compartmentalization) with FA symptoms in a nonclinical sample. Methods Participants (N = 755; 543 women; age range: 18–65; mean age: 28.22 ± 9.99 years) were evaluated using self‐report measures of FA, dissociation, eating disturbances, and general psychopathology. Results Compartmentalization experiences (defined as pathological over-segregation of higher mental functions) were independently associated with FA symptoms (β = 0.174; p = 0.013; CI = [0.008; 0.064]) even when confounding factors were controlled for. Conclusion This finding suggests that compartmentalization symptoms can have a role in the conceptualization of FA, with such two phenomena possibly sharing common pathogenic processes. Level of evidence: Level V, cross-sectional descriptive study.
