Neurofeedback

Functions, Applications and Effects presents a number of possible applications for neurofeedback in offender treatment, including perpetuators of domestic violence and various other forms of violent and anti-social behavior, certain forms of sexually abusive behavior, and criminal behavior of an obsessive–compulsive nature. A global description of this method is presented, followed by a brief overview of the empirical evidence of its efficacy in specific relevant treatment areas. To accomplish a targeted impact of neurofeedback on specific cortical functions, EEG-based local brain activity neurofeedback training was developed by Bauer et al. (2011). With this approach, an implemented algorithm automatically identifies and localizes EEG-sources in successive sLORETA solutions. Based on this information, the feedback is exclusively controlled by EEG-generating sources within a selected cortical region of training. In order to individually and precisely locate and define the region of training, the use of evoked potentials of known local origin is recommended. The authors investigate the effect of neurofeedback training on the motor performance and conscious motor processing of skilled dart players. Additionally, the authors investigate the effect of one session of neurofeedback training on the motor performance of elite and non-elite volleyball players. In the penultimate study, this collection proposes that prefrontal neurofeedback training would be accompanied by changes in the relative power of EEG bands and ratios of individual bands with increased effectiveness at higher numbers of sessions. Outcome measures included EEG and behavioral ratings by parents/caregivers.
