Analysing the electrical activity of the brain (the so-called language of the brain) can shed light to its underlying mechanisms. However, raw signal alone without analysis is not informative. Instead, quantitative frequency analysis using Fast Fourier Transformation (FFT) provides a useful tool to characterize the activity of the brain in detail. neoCateem, an EEG based neuroimaging software, translates the results of regional electrical activity into spectral colours and displays all frequency changes within one map, which corresponds mathematically to a 64 channel EEG. This processing results in enkephaloglyphs which represent spectral signatures of electrical brain activity under various recording conditions.
