NCT02480179

Brief Summary

The investigators plan to evaluate H.E.G. (Hematoencephalography) modality in brain modulation of appetite and food craving in a randomized controlled study. The H.E.G. will serve as the neurofeedback modality while the functional brain imaging will enable assessment and hopefully validation of changes brain activity related to food craving and self-control. H.E.G. is a relatively new neurofeedback technique which similar to fMRI, is based on changes in blood oxygenation level as a result of regional brain activation. The unique advantage of this technology regarding our enterprise is that it inheritably samples the two brain areas that are in our focus of interest: the superior orbito-frontal cortex (OFC) which Involved in self-control and reward processing, and the anterior cingulate cortex (ACC) which processes cognitive and emotional information. The investigators will combine HRV (Heart rate variability) biofeedback, which is a well-established treatment form in the investigators therapeutic sessions and will correlate functional neuroimaging with behavioral, anthropometric and laboratory data. The intervention name is: Measurements of blood flow changes within the brain and online visual feedback to the participant by a H.E.R. (Hematoencephalography) N.I,R (Near Infra Red sensor) sensor made by MindMedia, The Netherlands and a NEXUX4 Hardware, Bluetooth unit, Bio Trace Plus software made by MindMedia, The Netherlands. Hypothesis: The neurofeedback practice sessions are expected to facilitate improved control of blood flow to frontal brain areas, as a marker of brain activity in these areas

EXPERIMENTAL

Hematoencephalography bio/neurofeedback for Brain neural activity modulation. H.E.G. (hematoencephalography) based neurofeedback program. No drug use.

Device: H.E.G. (hematoencephalography) based neurofeedback

Interventions

H.E.G. is a relatively new neurofeedback technique which, similar to fMRI is based on differential oxygenated blood supply according to regional brain activity.
