Why neurofeedback? Prof Katya Rubia explains that traditional neuropharamacological interventions have specific limitations (drug abuse anyone?) that NF could address. Both EEG and fMRI NF have been tried with ADHD children each presenting different advantages and disadvantages. Cognitive performance ina ADHD- relevant tasks show improvement with NF treatment that can be directly compared to traditional therapies.

Dr. Klaus Mathias deals with issues like the transition from the image to the feedback signal and social feedback. 

Smile acts as a reward and brain activity regulates that smile, while social feedback improves learning. Cognitive reappraisal is an effective strategy for emotion regulation and frequently used in cognitive-behavioral treatment. However, PTSD patients often have difficulties reappraising negative stimuli. Neurofeedback based on real-time functional magnetic resonance imaging (rt-fMRI) enhances cognitive reappraisal and the regulation of amygdala involvement.

Dr Klados presented the effect of crystalized IQ in cerebellum’s functional network. Small world properties were examined and the concept of the Minimum Spanning Tree was employed in order to overcome graph comparison issues. The presented analysis linked the lower SWN-ness in high IQ females, in relation to low-IQ females and in relation to men, to a more efficient network organization in women, thereby reflecting different hemispheric organization between the two sexes.

Maria Karagianni, presented the "Insights into affective word processing and geriatric depression through the compination of Event-Related Potentials with Cortical Brain Network Analysis". It was an interesting speech about the way visual emotional stimuli effect cortical ERP activity and brain networks in comparison with healthy elderly and elderly with geriatric depression.
