“…The traditions of Aquinas were followed by Brentano [ 25 ], describing the creation of meaning in spiritual experiences; see also [ 26 , 27 ]. Considering the unity of brain, mind, and body, the energy consumption of the brain during the creation of meaning becomes an important research area [ 28 , 29 ]. Freeman’s pioneering experimental studies on spatio-temporal oscillations in brains produced several key findings, including the identification of sequences of metastable amplitude-modulated activity patterns (wave packets), which are associated with the meaning of the sensory experiences and produce consecutive meaningful decisions and actions [ 30 , 31 , 32 ].…”

It is of great interest to develop advanced sensory technologies allowing non-invasive monitoring of neural correlates of cognitive processing in people performing everyday tasks. A lot of progress has been reported in recent years in this research area using scalp EEG arrays, but the high level of noise in the electrode signals poses a lot of challenges. This study presents results of detailed statistical analysis of experimental data on the cycle of creation of knowledge and meaning in human brains under multiple cognitive modalities. We measure brain dynamics using a HydroCel Geodesic Sensor Net, 128-electrode dense-array electroencephalography (EEG). We compute a pragmatic information (PI) index derived from analytic amplitude and phase, by Hilbert transforming the EEG signals of 20 participants in six modalities, which combine various audiovisual stimuli, leading to different mental states, including relaxed and cognitively engaged conditions. We derive several relevant measures to classify different brain states based on the PI indices. We demonstrate significant differences between engaged brain states that require sensory information processing to create meaning and knowledge for intentional action, and relaxed-meditative brain states with less demand on psychophysiological resources. We also point out that different kinds of meanings may lead to different brain dynamics and behavioral responses.
