- Аннотация: One of the approaches to quantifying the complexity of systems is integrated information theory, as a mathematically complicated measure of how much “integrated information” a system possesses; it has been initially proposed to calculate how much consciousness a neural system has. In this study, we used this approach to assess whether there are any differences in hippocampal neural activity during skill acquisition of various degrees of difficulty. It was found that the value of the integrated information index, Φ, increased with the progress in the task. Moreover, Φ changed with an interval of 3–4 days until the animal was able to perform the skill. The results we obtained indicate that temporary abnormal neural activity (the temporary disorganization of the system state) is an essential stage in reorganization of neural activity that contributes to the achievement of a goal for the entire body.
