Szczegółowe poznanie, w jaki sposób pracuje mózg ludzki, otwiera szerokie możliwości w konstrukcji interfejsów bezpośredniej komunikacji pomiędzy człowiekiem a komputerem (brain-computer interface - BCI). Badania nad interfejsami mózg-komputer to rozwijająca się dynamicznie od około 15 lat tematyka, powstała na pograniczu wielu dziedzin naukowych. Celem było stworzenie prostego interfejsu BCI, opartego na wykrywaniu fali alfa, który umożliwi użytkownikowi sterowanie (włączanie/wyłączanie) urządzeniem elektrycznym. W tym celu wykorzystano kolejkę elektryczną, poruszającą się jedynie w przypadku wykrycia fali alfa w sygnale EEG.

Detailed knowledge of changes in electroencephalography signal (EEG) which occur during various human activities gives enormous possibilities to create brain-computer interfaces (BCI). The BCI research is progressively expanding and extremely important field in biomedical engineering. These brain-computer interfaces give hope to people with severe disabilities for improving their quality of life. There is also a wide range of BCI applications in the field of virtual reality and mind-controlled games. The aim of our project was to create a simple game using a railway toy, which is able to move by conscious changes in brain activity of players. The EEG signal is acquired using a set of electrodes placed on the heads of the players and it is processed in real time by dedicated algorithms. This project has been performed for the educational and cognitive purposes.

As a method of training neurofeedback has proved to be effective in education and therapy of children (e.g., with ADHD, autism spectrum or specific learning disorders). However, there are no neurofeedback training protocols targeting individuals with a mild intellectual disability. Therefore, I designed a neurofeedback procedure for children with this disability; it focuses on attention span training. In this study I presented the pre-planned procedure to the child’s parent to determine whether the proposed method is feasible for work with a child with a mild intellectual disability. After learning the parents’ opinion, I indicate the possible further stages of developing a neurofeedback strategy for working with children with a mild intellectual disability. Finally, I demonstrate the future directions of research and planning of neurofeedback procedures for individuals with special needs.

The aim of this article is to present art & science projects involving electroencephalography (EEG), and study them in terms of relationships between artistic narratives and medical procedures. Discussed are the works by pioneers of EEG applications in art (David Rosenboom, Alvin Lucier) and by contemporary artists (Lisa Park, Amy Karle), who are mainly interested in performances and relational installations. The author of the text analyses the projects with reference to the concept she introduces – biomediation (derived from Eugene Thacker’s theory of biomedia and a concept of mediation developed by Joanna Zylinska and Sarah Kember), pointing to the post- and transhumanist strategies used by the artists. She ponders on the extent to which the parameterisation and processing of bioelectric work of human brain may serve as a tool to expand the capacity of the human body-mind and thus create connections with ‘non-human’ constructs.

W artykule przedstawiono aplikację do samodzielnego treningu umysłu z wykorzystaniem neurofeedbacku. Aplikacja została stworzona w środowisku LabVIEW, z użyciem otwartej platformy BCI2000. Najważniejsze części aplikacji to: moduł zbierania danych oraz moduł przetwarzania sygnału EEG przy użyciu szybkiego przekształcenia Fouriera. Kluczowym elementem systemu jest moduł, który dla określonej przez użytkownika częstotliwości, dokonuje pomiaru energii sygnału. Wyniki wyświetlane są na panelu aplikacji użytkownika, zapewniając pożądane sprzężenie zwrotne.

This paper presents an application for self-training of the mind with the use of neurofeedback. The application was developed in LabVIEW environment, using the open BCI2000 platform. The most important parts of the application are data acquisition module and EEG signal processing module implementing Fast Fourier Transform. The key element of the system is the module that, for a user-specified frequency, measures signal energy. The results are then displayed to provide the desired feedback.

The present paper argues that the development of a new methodology in studying the brain has resulted in a change of our views on the way it works, has seen the emergence of new ideas, and a considerable modification of traditionally accepted theories. The most significant are neuroplasticity, negative activity network (NAT), the nature of aphasic disorders, and the approach to the localization of brain functions. New brain imaging techniques have confirmed also the ability to change the neuronal circuits by mental force. Moreover, new techniques have brought about a rise in new methods for both the diagnosis and rehabilitation of individuals with various brain disorders. Most valuable in this respect has proved to be neurofeedback. We have concentrated on the most important contributions of Prof. Pąchalska in the implementation and development of these new ideas on brain functioning. We also emphasize the fact that her theoretical considerations are firmly based upon her extensive (forty years) work with brain damaged patients.
