Abstract
This presentation describes the development and use of the art of encephalography in a new and more advanced way, whereby this qualitative tool where large quantities of brain data images are processed and converted into brain dynamics movie and then displayed for the purpose of visual discrimination associated with the different brain cognitive states, as well as the different stages of cognitive processes related to the cycle of creation of knowledge and meaning. The methodology we present is inspired by the art of encephalography, where this art is enhanced from the mere plotting of brain signals in the time domain to spatio-temporal frames that when presented in a sequence of plots, produces a brain dynamics movie which allows to visualize different patterns of behavior in different conditions produced by different stimuli based on experimental data. By careful observation of each of these movies, we learn to identify different structures and visual patterns where large-scale synchronizations and de-synchronizations are observed across different frequency bands. These movies also allow us to explore the temporal evolution of these spatial brain patterns where we can identify the different stages in the manifestation of the hypothesized cycle of creation of knowledge and meaning. We conjecture that movie viewing, will allow a better understanding of learning and adaptation. In summary, we can say that viewing brain dynamics movies will allow a significant impression of: Brain events for different measurement; brain events across bands and; the different stages of the cycle of creation of knowledge and meaning. The research team at The Embassy of Peace in Whitianga, New Zealand accomplished this work in close collaboration with Walter J. Freeman and Robert Kozma.
