The brain is a distributed network (DIPS) of multiple agents specialized in solving specific tasks and joining efforts to handle complex cognitive activities as a time of efficient cortical columns assemblies (CA).

The column distinct cortical layers generate different slow and fast currents that sum up into a total columnar oscillatory current that is low and noisy. The increment of the input activity triggered by sensory stimulation or internal activity created by reasoning, entrains not only the intrinsic activity of each column but also the activity of a defined number of neighboring columns. This entrainment increases the value of the different columnar that sum up into a larger current whose value heavily depends on the number of the entrained columns.

The input and oscillatory activity of all cortical areas recruited to support a cognitive task is organized into a Cortical Oscillatory Modular Processing (COMP) that generates a event related activity that may be identified in the EEG recorded while the individual is solving the task. These are segmented into four waves of Wi components.

Here, the sLORETA software was used to identify he input and oscillatory sources activated by different cognitive processing. The analysis of the temporal and spatial distribution of these sources revealed that and activity contributes to generate the distinct Wi components of the distinct supporting the cortical modular processing of any cognitive task. The source movement during the distinct entrains and integrates the sequential cortical processing COMP to update and unify the cognitive activity related to a task to be solved.
