GAAN is an active participant in a plethora of national and international projects in collaboration with several healthcare institutions, industries and enterprises. It demonstrates strong management capacity having coordinated a large number of EU grants in, FP7, and INTERREG programs. The GAAN group succeeded in recruiting a community cohort of nearly 400 individuals (18-90 years old) who underwent intensive neuroimaging (EEG/MEG) and cognitive assessment. Following are the group’s main projects.


This project aims in composing pervasive human-centered systems able to understand the human state (identity, emotions and behavior) in assistive environments using audiovisual and biological signals.


The purpose of this project is to investigate the effect of the intracranial light induction in the human brain, and its effectiveness in treating depression. The intervention effect will be investigated by comparing depressed to non-depressed adults.

MUSICPLAST, a general index of audiovisual incongruencies of abstract rules

The aim of this project is to differentiate the uni- and multi-sensory elements underpinning multisensory judgments of magnitude within and across the borders of the cognitive domain of non-symbolic numerosity using electroencephalographic and behavioral measurements. The mechanism supporting training induced plasticity in this process is investigated by comparing musicians to non-musicians.

Long Lasting Memories

Our affiliate group ASOSS coordinated the LLM project. The aim of this project was to engage seniors into computerized interventions of physical exercise occurring in the context of cognitive challenges. The effect of the intervention was investigated between 5 groups; 3 experimental groups engaged in an eight week cognitive and/or physical training, and 2 control groups: active and passive. The participants were cognitively intact individuals as well as seniors meeting the clinical criteria of Mild Cognitive Impairment (MCI) and Alzheimer’s disease (AD). By using EEG, the participants’ electrical potentials were recorded before and after the intervention at rest state and while passively viewing affective stimuli (pictures and words) rated along arousal and valence.


This was a collaborative project between the Medical School of the Aristotle University of Thessaloniki, Greece, and the Brain Science Institute of RIKEN, Japan. The purpose was to enable multi-channel physiological sensing for direct adaptation of computer user interfaces in affective interaction paradigms. By using MEG and EEG, the magnetic fields and electrical potentials respectively were recorded from healthy adults while passively viewing affective stimuli (pictures and words) rated along arousal and valence.
