The insight phenomenon and the digital visualization of the human brain activity

The problem of the transition of unconscious of neurophysiological mechanisms into conscious ones, is crucial problem for cognitive science. Methods of digital synthesis and image processing have been used to analyze the activity of large-scale neural networks of the human brain in threshold recognition conditions. Activity of large-scale neural networks in subthreshold, threshold and above-threshold conditions in the case of observing synthesized dynamic images is shown. Particular attention is paid to comparing images reflecting the state of brain activity (by measuring the oscillations of the BOLD signal) in subthreshold, threshold and above-threshold conditions among themselves and with respect to images of the distribution of activity of neural networks at rest. The presence of the maximum value of the BOLD signal, when the threshold was reached, was found in some areas of the brain and the activity of neural networks in other areas of the brain decreased.
