Abstract

 In the project inter@FAŢA, the creative team developed various algorithms for the generation of music, starting from real time monitored EEG. Among the music generating algorithms, together with other models, an EEG alpha spectrum analysis software was used, which was based on the difference of valence of sensors AF3-AF4. The post-performance analysis signals the correlation of these valence changes (change of potential difference between the left and right brain hemispheres) with the most intense moments of the performance and, respectively, with the most marked alternations of performance styles. The use of music and of the background sound produced, based on the EEG, emphasizes, thus, a deep, stable structure of the performance, measurable and reproducible in a number of performances. The spectator’s emotional participation is thus removed from its shroud of invisibility, and it becomes an element of visible action, accessible to other spectators. This paper looks into the work stage of the project in 2014; at present, it is developed according to the conclusions described herein.

Alexandru BERCEANU, Associate Professor at UNATC Bucharest, e-mail: zberceanu@yahoo.com

ALEXANDRU BERCEANU: independent stage director. He staged more than 15 plays in independent and state theatres, which were awarded national and international prizes. Owing to his interest in new dramaturgy and in the extension of performing expression scopes, Alexandru Berceanu contributes to interdisciplinary projects of neurocognitive research of performing arts and in the visual field, such as 1958-1958 Subversive and Immersive Installation or in the graphic novel Mickey on the Danube published by Jumătatea Plină. Berceanu is a member of dramAcum, an NGO for the development of new dramaturgy. At present, he is a doctoral student at the Babes-Bolyai University, Faculty of Theatre, and his doctoral thesis is on Violence in Performing Arts, from Hypnotic Power to Social Responsibility, coordinator PhD Miruna Runcan; he is also associate professor at UNATC IL Caragiale, department of Stage Directing.

Cătălin CREȚU, Associate Instructor at the Electroacoustic Music and Multimedia Center of the National University of Music Bucharest, e-mail: catcretu@yahoo.com

CĂTĂLIN CREȚU: is a composer, researcher in the field of electroacoustic music, audio-video interactivity and multimedia at the Electroacoustic Music and Multimedia Center of the National University of Music Bucharest. Since 2012 he is Associate Instructor at the same university. His habilitation (2008) was published in 2015 under the title: “From the sinus sound to the anatomy of shadow.

Grigore BURLOIU, Faculty of Electronics-Telecommunications and IT of UPB, e-mail: gburloiu@gmail.com

GRIGORE BURLOIU has been a doctoral student at the Faculty of Electronics-Telecommunications and IT of UPB since October 2013, where he researches strategies of augmentation of music representations in real time. He went in a research stage at IRCAM, Paris, and he drew up a laboratory study programme, for MA level, which he has been coordinating since 2013. It focuses on the development of software for creative fields, with a focus on the music elements, by using languages such as Supercollider, C++/OpenFrameworks, and especially Max/MSP.

Dragoș CÂRNECI, PhD in psychology, specialized in affective and developmental neurosciences, e-mail: dragos.cirneci@brainperform.ro

DRAGOŞ CȊRNECI: PhD in psychology, specialized in affective and developmental neurosciences. In 2004, he wrote the first Romanian handbook of developmental neurosciences. He has also published the works Origin of the mind; From viruses to beliefs (2013) and Stresul din mintea noastră şi războiul din lumea celulelor (2014). Starting from 2010, he has been involved in the field of psycho-neuro-immunology, by studying the relationship between cytokines and some brain mechanisms. He is also interested in the development of cognitive training techniques with a role in brain optimization and the prevention of neurodegeneration and he is the author of the first Romanian portal of brain training.
